-And now for the most boring daemon ever written!
-
-We will use the Ubuntu image to run a simple hello world daemon that
-will just print hello world to standard out every second. It will
-continue to do this until we stop it.
-
-**Steps:**
-
-    $ container_id=$(sudo docker run -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done")
-
-We are going to run a simple hello world daemon in a new container made
-from the `ubuntu` image.
-
- - **"sudo docker run -d "** run a command in a new container. We pass
-   "-d" so it runs as a daemon.
- - **"ubuntu"** is the image we want to run the command inside of.
- - **"/bin/sh -c"** is the command we want to run in the container
- - **"while true; do echo hello world; sleep 1; done"** is the mini
-   script we want to run, that will just print hello world once a
-   second until we stop it.
- - **$container_id** the output of the run command will return a
-   container id, we can use in future commands to see what is going on
-   with this process.

-While using Dockerfiles is the preferred way to create maintainable and

-then commit your live changes to an image.
-
-The goal of this example is to show you how you can modify your own
-Docker images by making changes to a running container, and then saving
-the results as a new image. We will do that by making a simple `hello
-world` Flask web application image.
-
-## Download the initial image
-
-Download the `shykes/pybuilder` Docker image from the `http://index.docker.io`
-registry.
-
-This image contains a `buildapp` script to download
-the web app and then `pip install` any required
-modules, and a `runapp` script that finds the
-`app.py` and runs it.
-
-    $ sudo docker pull shykes/pybuilder
-
-> **Note**: 
-> This container was built with a very old version of docker (May 2013 -
-> see [shykes/pybuilder](https://github.com/shykes/pybuilder) ), when the
-> Dockerfile format was different, but the image can
-> still be used now.
-
-## Interactively make some modifications
-
-We then start a new container running interactively using the image.
-First, we set a `URL` variable that points to a
-tarball of a simple helloflask web app, and then we run a command
-contained in the image called `buildapp`, passing it
-the `$URL` variable. The container is given a name
-`pybuilder_run` which we will use in the next steps.
-
-While this example is simple, you could run any number of interactive
-commands, try things out, and then exit when you're done.
-
-    $ sudo docker run -i -t --name pybuilder_run shykes/pybuilder bash
-
-    $$ URL=http://github.com/shykes/helloflask/archive/master.tar.gz
-    $$ /usr/local/bin/buildapp $URL
-    [...]
-    $$ exit
-
-## Commit the container to create a new image
-
-Save the changes we just made in the container to a new image called
-`/builds/github.com/shykes/helloflask/master`. You
-now have 3 different ways to refer to the container: name
-`pybuilder_run`, short-id `c8b2e8228f11`, or long-id
-`c8b2e8228f11b8b3e492cbf9a49923ae66496230056d61e07880dc74c5f495f9`.
-

-    c8b2e8228f11b8b3e492cbf9a49923ae66496230056d61e07880dc74c5f495f9
-
-## Run the new image to start the web worker
-
-Use the new image to create a new container with network port 5000
-mapped to a local port
-
-    $ sudo docker run -d -p 5000 --name web_worker /builds/github.com/shykes/helloflask/master /usr/local/bin/runapp
-
- - **"docker run -d "** run a command in a new container. We pass "-d"
-   so it runs as a daemon.
- - **"-p 5000"** the web app is going to listen on this port, so it
-   must be mapped from the container to the host system.
- - **/usr/local/bin/runapp** is the command which starts the web app.
-
-## View the container logs
-
-View the logs for the new `web_worker` container and
-if everything worked as planned you should see the line
-`Running on http://0.0.0.0:5000/` in the log output.
-
-To exit the view without stopping the container, hit Ctrl-C, or open
-another terminal and continue with the example while watching the result
-in the logs.
-
-    $ sudo docker logs -f web_worker
-    * Running on http://0.0.0.0:5000/
-
-## See the webapp output
-
-Look up the public-facing port which is NAT-ed. Find the private port
-used by the container and store it inside of the `WEB_PORT`
-variable.
-
-Access the web app using the `curl` binary. If
-everything worked as planned you should see the line
-`Hello world!` inside of your console.
-
-    $ WEB_PORT=$(sudo docker port web_worker 5000 | awk -F: '{ print $2 }')
-
-    # install curl if necessary, then ...
-    $ curl http://127.0.0.1:$WEB_PORT
-    Hello world!
-
-## Clean up example containers and images
-
-    $ sudo docker ps --all
-
-List `--all` the Docker containers. If this
-container had already finished running, it will still be listed here
-with a status of `Exit 0`.
-
-    $ sudo docker stop web_worker
-    $ sudo docker rm web_worker pybuilder_run
-    $ sudo docker rmi /builds/github.com/shykes/helloflask/master shykes/pybuilder:latest

-And now stop the running web worker, and delete the containers, so that
-we can then delete the images that we used.

-# An Introduction to working with Docker
-
-**Getting started with Docker**
-
-> **Note:** 
-> If you would like to see how a specific command
-> works, check out the glossary of all available client
-> commands on our [Commands Reference](/reference/commandline/cli).
-
-## Introduction
-
-In the [Understanding Docker](understanding-docker.md) section we
-covered the components that make up Docker, learned about the underlying
-technology and saw *how* everything works.
-
-Now, let's get an introduction to the basics of interacting with Docker.
-
-> **Note:** 
-> This page assumes you have a host with a running Docker
-> daemon and access to a Docker client. To see how to install Docker on
-> a variety of platforms see the [installation
-> section](/installation/#installation).
-
-## How to use the client
-
-The client provides you a command-line interface to Docker. It is
-accessed by running the `docker` binary.
-
-> **Tip:** 
-> The below instructions can be considered a summary of our
-> [interactive tutorial](https://www.docker.io/gettingstarted). If you
-> prefer a more hands-on approach without installing anything, why not
-> give that a shot and check out the
-> [tutorial](https://www.docker.io/gettingstarted).
-
-The `docker` client usage is pretty simple. Each action you can take
-with Docker is a command and each command can take a series of
-flags and arguments.
-
-    # Usage:  [sudo] docker [flags] [command] [arguments] ..
-    # Example:
-    $ docker run -i -t ubuntu /bin/bash
-
-## Using the Docker client
-
-Let's get started with the Docker client by running our first Docker
-command. We're going to use the `docker version` command to return
-version information on the currently installed Docker client and daemon.
-
-    # Usage: [sudo] docker version
-    # Example:
-    $ docker version
-
-This command will not only provide you the version of Docker client and
-daemon you are using, but also the version of Go (the programming
-language powering Docker).
-
-    Client version: 0.8.0
-    Go version (client): go1.2
-
-    Git commit (client): cc3a8c8
-    Server version: 0.8.0
-
-    Git commit (server): cc3a8c8
-    Go version (server): go1.2
-
-    Last stable version: 0.8.0
-
-### Seeing what the Docker client can do
-
-We can see all of the commands available to us with the Docker client by
-running the `docker` binary without any options.
-
-    # Usage: [sudo] docker
-    # Example:
-    $ docker
-
-You will see a list of all currently available commands.
-
-    Commands:
-         attach    Attach to a running container
-         build     Build an image from a Dockerfile
-         commit    Create a new image from a container's changes
-    . . .
-
-### Seeing Docker command usage
-
-You can also zoom in and review the usage for specific Docker commands.
-
-Try typing Docker followed with a `[command]` to see the usage for that
-command:
-
-    # Usage: [sudo] docker [command] [--help]
-    # Example:
-    $ docker attach
-    Help output . . .
-
-Or you can also pass the `--help` flag to the `docker` binary.
-
-    $ docker images --help
-
-This will display the help text and all available flags:
-
-    Usage: docker attach [OPTIONS] CONTAINER
-
-    Attach to a running container
-
-      --no-stdin=false: Do not attach stdin
-      --sig-proxy=true: Proxify all received signal to the process (even in non-tty mode)
-
-## Working with images
-
-Let's get started with using Docker by working with Docker images, the
-building blocks of Docker containers.
-
-### Docker Images
-
-As we've discovered a Docker image is a read-only template that we build
-containers from. Every Docker container is launched from an image. You can
-use both images provided by Docker, such as the base `ubuntu` image,
-as well as images built by others. For example we can build an image that
-runs Apache and our own web application as a starting point to launch containers.
-
-### Searching for images
-
-To search for Docker image we use the `docker search` command. The
-`docker search` command returns a list of all images that match your
-search criteria, together with some useful information about that image.
-
-This information includes social metrics like how many other people like
-the image: we call these "likes" *stars*. We also tell you if an image
-is *trusted*. A *trusted* image is built from a known source and allows
-you to introspect in greater detail how the image is constructed.
-
-    # Usage: [sudo] docker search [image name]
-    # Example:
-    $ docker search nginx
-
-    NAME                               DESCRIPTION                                     STARS  OFFICIAL   TRUSTED
-    dockerfile/nginx                   Trusted Nginx (http://nginx.org/) Build         6                 [OK]
-    paintedfox/nginx-php5              A docker image for running Nginx with PHP5.     3                 [OK]
-    dockerfiles/django-uwsgi-nginx     Dockerfile and configuration files to buil...   2                 [OK]
-    . . .
-
-> **Note:** 
-> To learn more about trusted builds, check out
-> [this](http://blog.docker.io/2013/11/introducing-trusted-builds) blog
-> post.
-
-### Downloading an image
-
-Once we find an image we'd like to download we can pull it down from
-[Docker.io](https://index.docker.io) using the `docker pull` command.
-
-    # Usage: [sudo] docker pull [image name]
-    # Example:
-    $ docker pull dockerfile/nginx
-
-    Pulling repository dockerfile/nginx
-    0ade68db1d05: Pulling dependent layers
-    27cf78414709: Download complete
-    b750fe79269d: Download complete
-    . . .
-
-As you can see, Docker will download, one by one, all the layers forming
-the image.
-
-### Listing available images
-
-You may already have some images you've pulled down or built yourself
-and you can use the `docker images` command to see the images
-available to you locally.
-
-    # Usage: [sudo] docker images
-    # Example:
-    $ docker images
-
-    REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
-    myUserName/nginx    latest              a0d6c70867d2        41 seconds ago      578.8 MB
-    nginx               latest              173c2dd28ab2        3 minutes ago       578.8 MB
-    dockerfile/nginx    latest              0ade68db1d05        3 weeks ago         578.8 MB
-
-### Building our own images
-
-You can build your own images using a `Dockerfile` and the `docker
-build` command. The `Dockerfile` is very flexible and provides a
-powerful set of instructions for building applications into Docker
-images. To learn more about the `Dockerfile` see the [`Dockerfile`
-Reference](/reference/builder/) and [tutorial](https://www.docker.io/learn/dockerfile/).
-
-## Working with containers
-
-### Docker Containers
-
-Docker containers run your applications and are built from Docker
-images. In order to create or start a container, you need an image. This
-could be the base `ubuntu` image or an image built and shared with you
-or an image you've built yourself.
-
-### Running a new container from an image
-
-The easiest way to create a new container is to *run* one from an image
-using the `docker run` command.
-
-    # Usage: [sudo] docker run [arguments] ..
-    # Example:
-    $ docker run -d --name nginx_web nginx /usr/sbin/nginx
-    25137497b2749e226dd08f84a17e4b2be114ddf4ada04125f130ebfe0f1a03d3
-
-This will create a new container from an image called `nginx` which will
-launch the command `/usr/sbin/nginx` when the container is run. We've
-also given our container a name, `nginx_web`. When the container is run
-Docker will return a container ID, a long string that uniquely
-identifies our container. We use can the container's name or its string
-to work with it.
-
-Containers can be run in two modes:
-
-* Interactive;
-* Daemonized;
-
-An interactive container runs in the foreground and you can connect to
-it and interact with it, for example sign into a shell on that
-container. A daemonized container runs in the background.
-
-A container will run as long as the process you have launched inside it
-is running, for example if the `/usr/bin/nginx` process stops running
-the container will also stop.
-
-### Listing containers
-
-We can see a list of all the containers on our host using the `docker
-ps` command. By default the `docker ps` command only shows running
-containers. But we can also add the `-a` flag to show *all* containers:
-both running and stopped.
-
-    # Usage: [sudo] docker ps [-a]
-    # Example:
-    $ docker ps
-
-    CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS              PORTS                NAMES
-    842a50a13032        $ dockerfile/nginx:latest   nginx               35 minutes ago      Up 30 minutes       0.0.0.0:80->80/tcp   nginx_web
-
-### Stopping a container
-
-You can use the `docker stop` command to stop an active container. This
-will gracefully end the active process.
-
-    # Usage: [sudo] docker stop [container ID]
-    # Example:
-    $ docker stop nginx_web
-    nginx_web
-
-If the `docker stop` command succeeds it will return the name of
-the container it has stopped.
-
-> **Note:** 
-> If you want you to more aggressively stop a container you can use the
-> `docker kill` command.
-
-### Starting a Container
-
-Stopped containers can be started again.
-
-    # Usage: [sudo] docker start [container ID]
-    # Example:
-    $ docker start nginx_web
-    nginx_web
-
-If the `docker start` command succeeds it will return the name of the
-freshly started container.
-

-how to run and work with our first container.

-# Redirect Ports
-
-## Introduction
-
-Interacting with a service is commonly done through a connection to a
-port. When this service runs inside a container, one can connect to the
-port after finding the IP address of the container as follows:
-
-    # Find IP address of container with ID <container_id>
-    $ docker inspect --format='{{.NetworkSettings.IPAddress}}' <container_id>
-
-However, this IP address is local to the host system and the container
-port is not reachable by the outside world. Furthermore, even if the
-port is used locally, e.g. by another container, this method is tedious
-as the IP address of the container changes every time it starts.
-
-Docker addresses these two problems and give a simple and robust way to
-access services running inside containers.
-
-To allow non-local clients to reach the service running inside the
-container, Docker provide ways to bind the container port to an
-interface of the host system. To simplify communication between
-containers, Docker provides the linking mechanism.
-
-## Auto map all exposed ports on the host
-
-To bind all the exposed container ports to the host automatically, use
-`docker run -P <imageid>`. The mapped host ports will be auto-selected
-from a pool of unused ports (49000..49900), and you will need to use
-`docker ps`, `docker inspect <container_id>` or `docker port
-<container_id> <port>` to determine what they are.
-
-## Binding a port to a host interface
-
-To bind a port of the container to a specific interface of the host
-system, use the `-p` parameter of the `docker run` command:
-
-    # General syntax
-    $ docker run -p [([<host_interface>:[host_port]])|(<host_port>):]<container_port>[/udp] <image> <cmd>
-
-When no host interface is provided, the port is bound to all available
-interfaces of the host machine (aka INADDR_ANY, or 0.0.0.0). When no
-host port is provided, one is dynamically allocated. The possible
-combinations of options for TCP port are the following:
-
-    # Bind TCP port 8080 of the container to TCP port 80 on 127.0.0.1 of the host machine.
-    $ docker run -p 127.0.0.1:80:8080 <image> <cmd>
-
-    # Bind TCP port 8080 of the container to a dynamically allocated TCP port on 127.0.0.1 of the host machine.
-    $ docker run -p 127.0.0.1::8080 <image> <cmd>
-
-    # Bind TCP port 8080 of the container to TCP port 80 on all available interfaces of the host machine.
-    $ docker run -p 80:8080 <image> <cmd>
-
-    # Bind TCP port 8080 of the container to a dynamically allocated TCP port on all available interfaces of the host machine.
-    $ docker run -p 8080 <image> <cmd>
-
-UDP ports can also be bound by adding a trailing `/udp`. All the
-combinations described for TCP work. Here is only one example:
-
-    # Bind UDP port 5353 of the container to UDP port 53 on 127.0.0.1 of the host machine.
-    $ docker run -p 127.0.0.1:53:5353/udp <image> <cmd>
-
-The command `docker port` lists the interface and port on the host
-machine bound to a given container port. It is useful when using
-dynamically allocated ports:
-
-    # Bind to a dynamically allocated port
-    $ docker run -p 127.0.0.1::8080 --name dyn-bound <image> <cmd>
-
-    # Lookup the actual port
-    $ docker port dyn-bound 8080
-    127.0.0.1:49160
-
-## Linking a container
-
-Communication between two containers can also be established in a
-Docker-specific way called linking.
-
-To briefly present the concept of linking, let us consider two
-containers: `server`, containing the service, and `client`, accessing
-the service. Once `server` is running, `client` is started and links to
-server. Linking sets environment variables in `client` giving it some
-information about `server`.  In this sense, linking is a method of
-service discovery.
-
-Let us now get back to our topic of interest; communication between the
-two containers. We mentioned that the tricky part about this
-communication was that the IP address of `server` was not fixed.
-Therefore, some of the environment variables are going to be used to
-inform `client` about this IP address. This process called exposure, is
-possible because the `client` is started after the `server` has been started.
-
-Here is a full example. On `server`, the port of interest is exposed.
-The exposure is done either through the `--expose` parameter to the
-`docker run` command, or the `EXPOSE` build command in a `Dockerfile`:
-
-    # Expose port 80
-    $ docker run --expose 80 --name server <image> <cmd>
-
-The `client` then links to the `server`:
-
-    # Link
-    $ docker run --name client --link server:linked-server <image> <cmd>
-
-Here `client` locally refers to `server` as `linked-server`. The following
-environment variables, among others, are available on `client`:
-
-    # The default protocol, ip, and port of the service running in the container
-    $ LINKED-SERVER_PORT=tcp://172.17.0.8:80
-
-    # A specific protocol, ip, and port of various services
-    $ LINKED-SERVER_PORT_80_TCP=tcp://172.17.0.8:80
-    $ LINKED-SERVER_PORT_80_TCP_PROTO=tcp
-    $ LINKED-SERVER_PORT_80_TCP_ADDR=172.17.0.8
-    $ LINKED-SERVER_PORT_80_TCP_PORT=80
-
-This tells `client` that a service is running on port 80 of `server` and
-that `server` is accessible at the IP address `172.17.0.8`:
-
-> **Note:**
-> Using the `-p` parameter also exposes the port.

-# Link Containers
-
-## Introduction
-
-From version 0.6.5 you are now able to `name` a container and `link` it
-to another container by referring to its name. This will create a parent
--> child relationship where the parent container can see selected
-information about its child.
-
-## Container Naming
-
-You can now name your container by using the `--name` flag. If no name
-is provided, Docker will automatically generate a name. You can see this
-name using the `docker ps` command.
-
-    # format is "sudo docker run --name <container_name> <image_name> <command>"

-## Links: service discovery for docker
-
-Links allow containers to discover and securely communicate with each
-other by using the flag `--link name:alias`. Inter-container
-communication can be disabled with the daemon flag `--icc=false`. With
-this flag set to `false`, Container A cannot access Container B unless
-explicitly allowed via a link. This is a huge win for securing your
-containers. When two containers are linked together Docker creates a
-parent child relationship between the containers. The parent container
-will be able to access information via environment variables of the
-child such as name, exposed ports, IP and other selected environment
-variables.
-
-When linking two containers Docker will use the exposed ports of the
-container to create a secure tunnel for the parent to access. If a
-database container only exposes port 8080 then the linked container will
-only be allowed to access port 8080 and nothing else if inter-container
-communication is set to false.
-
-For example, there is an image called `crosbymichael/redis` that exposes
-the port 6379 and starts the Redis server. Let's name the container as
-`redis` based on that image and run it as daemon.
-
-    $ sudo docker run -d --name redis crosbymichael/redis
-
-We can issue all the commands that you would expect using the name
-`redis`; start, stop, attach, using the name for our container. The name
-also allows us to link other containers into this one.
-
-Next, we can start a new web application that has a dependency on Redis
-and apply a link to connect both containers. If you noticed when running
-our Redis server we did not use the `-p` flag to publish the Redis port
-to the host system. Redis exposed port 6379 and this is all we need to
-establish a link.
-
-    $ sudo docker run -t -i --link redis:db --name webapp ubuntu bash
-
-When you specified `--link redis:db` you are telling Docker to link the
-container named `redis` into this new container with the alias `db`.
-Environment variables are prefixed with the alias so that the parent
-container can access network and environment information from the
-containers that are linked into it.
-
-If we inspect the environment variables of the second container, we
-would see all the information about the child container.

-## Resolving Links by Name
-
-> *Note:* New in version v0.11.
-
-Linked containers can be accessed by hostname.  Hostnames are mapped by
-appending entries to '/etc/hosts' using the linked container's alias.
-
-For example, linking a container using '--link redis:db' will generate
-the following '/etc/hosts' file:
-
-    root@6541a75d44a0:/# cat /etc/hosts
-    172.17.0.3  6541a75d44a0
-    172.17.0.2  db
-
-    127.0.0.1   localhost
-    ::1     localhost ip6-localhost ip6-loopback
-    fe00::0     ip6-localnet
-    ff00::0     ip6-mcastprefix
-    ff02::1     ip6-allnodes
-    ff02::2     ip6-allrouters
-    root@6541a75d44a0:/#
-
-Using this mechanism, you can communicate with the linked container by
-name:
-
-    root@6541a75d44a0:/# echo PING | redis-cli -h db
-    PONG
-    root@6541a75d44a0:/#

-# Share Directories via Volumes
-
-## Introduction
-
-A *data volume* is a specially-designated directory within one or more
-containers that bypasses the [*Union File
-System*](/terms/layer/#ufs-def) to provide several useful features for
-persistent or shared data:
-
- - **Data volumes can be shared and reused between containers:**  
-   This is the feature that makes data volumes so powerful. You can
-   use it for anything from hot database upgrades to custom backup or
-   replication tools. See the example below.
- - **Changes to a data volume are made directly:**  
-   Without the overhead of a copy-on-write mechanism. This is good for
-   very large files.
- - **Changes to a data volume will not be included at the next commit:**  
-   Because they are not recorded as regular filesystem changes in the
-   top layer of the [*Union File System*](/terms/layer/#ufs-def)
- - **Volumes persist until no containers use them:**  
-   As they are a reference counted resource. The container does not need to be
-   running to share its volumes, but running it can help protect it
-   against accidental removal via `docker rm`.
-
-Each container can have zero or more data volumes.
-
-## Getting Started
-
-Using data volumes is as simple as adding a `-v` parameter to the
-`docker run` command. The `-v` parameter can be used more than once in
-order to create more volumes within the new container. To create a new
-container with two new volumes:
-
-    $ docker run -v /var/volume1 -v /var/volume2 busybox true
-
-This command will create the new container with two new volumes that
-exits instantly (`true` is pretty much the smallest, simplest program
-that you can run). You can then mount its volumes in any other container
-using the `run` `--volumes-from` option; irrespective of whether the
-volume container is running or not.
-
-Or, you can use the `VOLUME` instruction in a `Dockerfile` to add one or
-more new volumes to any container created from that image:
-
-    # BUILD-USING:        $ docker build -t data .
-    # RUN-USING:          $ docker run --name DATA data
-    FROM          busybox
-    VOLUME        ["/var/volume1", "/var/volume2"]
-    CMD           ["/bin/true"]
-
-### Creating and mounting a Data Volume Container
-
-If you have some persistent data that you want to share between
-containers, or want to use from non-persistent containers, it's best to
-create a named Data Volume Container, and then to mount the data from
-it.
-
-Create a named container with volumes to share (`/var/volume1` and
-`/var/volume2`):
-
-    $ docker run -v /var/volume1 -v /var/volume2 --name DATA busybox true
-
-Then mount those data volumes into your application containers:
-
-    $ docker run -t -i --rm --from DATA --name client1 ubuntu bash
-
-You can use multiple `-volumes-from` parameters to bring together
-multiple data volumes from multiple containers.
-
-Interestingly, you can mount the volumes that came from the `DATA`
-container in yet another container via the `client1` middleman
-container:
-
-    $ docker run -t -i --rm --volumes-from client1 --name client2 ubuntu bash
-
-This allows you to abstract the actual data source from users of that
-data, similar to [*Ambassador Pattern Linking*](
-../ambassador_pattern_linking/#ambassador-pattern-linking).
-
-If you remove containers that mount volumes, including the initial DATA
-container, or the middleman, the volumes will not be deleted until there
-are no containers still referencing those volumes. This allows you to
-upgrade, or effectively migrate data volumes between containers.
-
-### Mount a Host Directory as a Container Volume:
-
-    -v=[]: Create a bind mount with: [host-dir]:[container-dir]:[rw|ro].
-
-You must specify an absolute path for `host-dir`. If `host-dir` is
-missing from the command, then Docker creates a new volume. If
-`host-dir` is present but points to a non-existent directory on the
-host, Docker will automatically create this directory and use it as the
-source of the bind-mount.
-
-Note that this is not available from a `Dockerfile` due the portability
-and sharing purpose of it. The `host-dir` volumes are entirely
-host-dependent and might not work on any other machine.
-
-For example:
-
-    # Usage:
-    # sudo docker run [OPTIONS] -v /(dir. on host):/(dir. in container):(Read-Write or Read-Only) [ARG..]
-    # Example:
-    $ sudo docker run -i -t -v /var/log:/logs_from_host:ro ubuntu bash
-
-The command above mounts the host directory `/var/log` into the
-container with *read only* permissions as `/logs_from_host`.
-
-New in version v0.5.0.
-
-### Note for OS/X users and remote daemon users:
-
-OS/X users run `boot2docker` to create a minimalist virtual machine
-running the docker daemon. That virtual machine then launches docker
-commands on behalf of the OS/X command line. The means that `host
-directories` refer to directories in the `boot2docker` virtual machine,
-not the OS/X filesystem.
-
-Similarly, anytime when the docker daemon is on a remote machine, the
-`host directories` always refer to directories on the daemon's machine.
-
-### Backup, restore, or migrate data volumes
-
-You cannot back up volumes using `docker export`, `docker save` and
-`docker cp` because they are external to images. Instead you can use
-`--volumes-from` to start a new container that can access the
-data-container's volume. For example:
-
-    $ sudo docker run --rm --volumes-from DATA -v $(pwd):/backup busybox tar cvf /backup/backup.tar /data
-
- - `-rm`:  
-   remove the container when it exits
- - `--volumes-from DATA`:  
-   attach to the volumes shared by the `DATA` container
- - `-v $(pwd):/backup`:  
-   bind mount the current directory into the container; to write the tar file to
- - `busybox`:
-   a small simpler image - good for quick maintenance
- - `tar cvf /backup/backup.tar /data`:  
-   creates an uncompressed tar file of all the files in the `/data` directory
-
-Then to restore to the same container, or another that you've made
-elsewhere:
-
-    # create a new data container
-    $ sudo docker run -v /data --name DATA2 busybox true
-    # untar the backup files into the new container᾿s data volume
-    $ sudo docker run --rm --volumes-from DATA2 -v $(pwd):/backup busybox tar xvf /backup/backup.tar
-    data/
-    data/sven.txt
-    # compare to the original container
-    $ sudo docker run --rm --volumes-from DATA -v `pwd`:/backup busybox ls /data
-    sven.txt
-
-You can use the basic techniques above to automate backup, migration and
-restore testing using your preferred tools.
-
-## Known Issues
-
- - [Issue 2702](https://github.com/dotcloud/docker/issues/2702):
-    "lxc-start: Permission denied - failed to mount" could indicate a
-    permissions problem with AppArmor. Please see the issue for a
-    workaround.
- - [Issue 2528](https://github.com/dotcloud/docker/issues/2528): the
-    busybox container is used to make the resulting container as small
-    and simple as possible - whenever you need to interact with the data
-    in the volume you mount it into another container.

-# Share Images via Repositories
-
-## Introduction
-
-Docker is not only a tool for creating and managing your own
-[*containers*](/terms/container/#container-def) – **Docker is also a
-tool for sharing**. A *repository* is a shareable collection of tagged
-[*images*](/terms/image/#image-def) that together create the file
-systems for containers. The repository's name is a label that indicates
-the provenance of the repository, i.e. who created it and where the
-original copy is located.
-
-You can find one or more repositories hosted on a *registry*. There are
-two types of *registry*: public and private. There's also a default
-*registry* that Docker uses which is called
-[Docker.io](http://index.docker.io).
-[Docker.io](http://index.docker.io) is the home of "top-level"
-repositories and public "user" repositories.  The Docker project
-provides [Docker.io](http://index.docker.io) to host public and [private
-repositories](https://index.docker.io/plans/), namespaced by user. We
-provide user authentication and search over all the public repositories.
-
-Docker acts as a client for these services via the `docker search`,
-`pull`, `login` and `push` commands.
-
-## Repositories
-
-### Local Repositories
-
-Docker images which have been created and labeled on your local Docker
-server need to be pushed to a Public (by default they are pushed to
-[Docker.io](http://index.docker.io)) or Private registry to be shared.
-
-### Public Repositories
-
-There are two types of public repositories: *top-level* repositories
-which are controlled by the Docker team, and *user* repositories created
-by individual contributors. Anyone can read from these repositories –
-they really help people get started quickly! You could also use
-[*Trusted Builds*](#trusted-builds) if you need to keep control of who
-accesses your images.
-
-- Top-level repositories can easily be recognized by **not** having a
-  `/` (slash) in their name. These repositories represent trusted images
-  provided by the Docker team.
-- User repositories always come in the form of `<username>/<repo_name>`.
-  This is what your published images will look like if you push to the
-  public [Docker.io](http://index.docker.io) registry.
-- Only the authenticated user can push to their *username* namespace on
-  a [Docker.io](http://index.docker.io) repository.
-- User images are not curated, it is therefore up to you whether or not
-  you trust the creator of this image.
-
-### Private repositories
-
-You can also create private repositories on
-[Docker.io](https://index.docker.io/plans/). These allow you to store
-images that you don't want to share publicly. Only authenticated users
-can push to private repositories.
-
-## Find Public Images on Docker.io
-
-You can search the [Docker.io](https://index.docker.io) registry or
-using the command line interface. Searching can find images by name,
-user name or description:
-
-    $ sudo docker help search
-    Usage: docker search NAME
-
-    Search the docker index for images
-
-      --no-trunc=false: Don᾿t truncate output
-    $ sudo docker search centos
-    Found 25 results matching your query ("centos")
-    NAME                             DESCRIPTION
-    centos
-    slantview/centos-chef-solo       CentOS 6.4 with chef-solo.
-    ...
-
-There you can see two example results: `centos` and
-`slantview/centos-chef-solo`. The second result shows that it comes from
-the public repository of a user, `slantview/`, while the first result
-(`centos`) doesn't explicitly list a repository so it comes from the
-trusted top-level namespace. The `/` character separates a user's
-repository and the image name.
-
-Once you have found the image name, you can download it:
-
-    # sudo docker pull <value>
-    $ sudo docker pull centos
-    Pulling repository centos
-    539c0211cd76: Download complete
-
-What can you do with that image? Check out the
-[*Examples*](/examples/#example-list) and, when you're ready with your
-own image, come back here to learn how to share it.
-
-## Contributing to Docker.io
-
-Anyone can pull public images from the
-[Docker.io](http://index.docker.io) registry, but if you would like to
-share one of your own images, then you must register a unique user name
-first. You can create your username and login on
-[Docker.io](https://index.docker.io/account/signup/), or by running
-
-    $ sudo docker login
-
-This will prompt you for a username, which will become a public
-namespace for your public repositories.
-
-If your username is available then `docker` will also prompt you to
-enter a password and your e-mail address. It will then automatically log
-you in. Now you're ready to commit and push your own images!
-
-> **Note:**
-> Your authentication credentials will be stored in the [`.dockercfg`
-> authentication file](#authentication-file).
-
-## Committing a Container to a Named Image
-
-When you make changes to an existing image, those changes get saved to a
-container's file system. You can then promote that container to become
-an image by making a `commit`. In addition to converting the container
-to an image, this is also your opportunity to name the image,
-specifically a name that includes your user name from
-[Docker.io](http://index.docker.io) (as you did a `login` above) and a
-meaningful name for the image.
-
-    # format is "sudo docker commit <container_id> <username>/<imagename>"
-    $ sudo docker commit $CONTAINER_ID myname/kickassapp
-
-## Pushing a repository to its registry
-
-In order to push an repository to its registry you need to have named an
-image, or committed your container to a named image (see above)
-
-Now you can push this repository to the registry designated by its name
-or tag.
-
-    # format is "docker push <username>/<repo_name>"
-    $ sudo docker push myname/kickassapp
-
-## Trusted Builds
-
-Trusted Builds automate the building and updating of images from GitHub
-or BitBucket, directly on Docker.io. It works by adding a commit hook to
-your selected repository, triggering a build and update when you push a
-commit.
-
-### To setup a trusted build
-
-1.  Create a [Docker.io account](https://index.docker.io/) and login.
-2.  Link your GitHub or BitBucket account through the [`Link Accounts`](https://index.docker.io/account/accounts/) menu.
-3.  [Configure a Trusted build](https://index.docker.io/builds/).
-4.  Pick a GitHub or BitBucket project that has a `Dockerfile` that you want to build.
-5.  Pick the branch you want to build (the default is the `master` branch).
-6.  Give the Trusted Build a name.
-7.  Assign an optional Docker tag to the Build.
-8.  Specify where the `Dockerfile` is located. The default is `/`.
-
-Once the Trusted Build is configured it will automatically trigger a
-build, and in a few minutes, if there are no errors, you will see your
-new trusted build on the [Docker.io](https://index.docker.io) Registry.
-It will stay in sync with your GitHub and BitBucket repository until you
-deactivate the Trusted Build.
-
-If you want to see the status of your Trusted Builds you can go to your
-[Trusted Builds page](https://index.docker.io/builds/) on the Docker.io,
-and it will show you the status of your builds, and the build history.
-
-Once you've created a Trusted Build you can deactivate or delete it. You
-cannot however push to a Trusted Build with the `docker push` command.
-You can only manage it by committing code to your GitHub or BitBucket
-repository.
-
-You can create multiple Trusted Builds per repository and configure them
-to point to specific `Dockerfile`'s or Git branches.
-
-## Private Registry
-
-Private registries are possible by hosting [your own
-registry](https://github.com/dotcloud/docker-registry).
-
-> **Note**:
-> You can also use private repositories on
-> [Docker.io](https://index.docker.io/plans/).
-
-To push or pull to a repository on your own registry, you must prefix
-the tag with the address of the registry's host (a `.` or `:` is used to
-identify a host), like this:
-
-    # Tag to create a repository with the full registry location.
-    # The location (e.g. localhost.localdomain:5000) becomes
-    # a permanent part of the repository name
-    $ sudo docker tag 0u812deadbeef localhost.localdomain:5000/repo_name
-
-    # Push the new repository to its home location on localhost
-    $ sudo docker push localhost.localdomain:5000/repo_name
-
-Once a repository has your registry's host name as part of the tag, you
-can push and pull it like any other repository, but it will **not** be
-searchable (or indexed at all) on [Docker.io](http://index.docker.io),
-and there will be no user name checking performed. Your registry will
-function completely independently from the
-[Docker.io](http://index.docker.io) registry.

-http://blog.docker.io/2013/07/how-to-use-your-own-registry/)
-
-## Authentication File
-
-The authentication is stored in a JSON file, `.dockercfg`, located in
-your home directory. It supports multiple registry URLs.
-
-The `docker login` command will create the:
-
-    [https://index.docker.io/v1/](https://index.docker.io/v1/)
-
-key.
-
-The `docker login https://my-registry.com` command will create the:
-
-    [https://my-registry.com](https://my-registry.com)
-
-key.
-
-For example:
-
-    {
-         "https://index.docker.io/v1/": {
-                 "auth": "xXxXxXxXxXx=",
-                 "email": "email@example.com"
-         },
-         "https://my-registry.com": {
-                 "auth": "XxXxXxXxXxX=",
-                 "email": "email@my-registry.com"
-         }
-    }
-
-The `auth` field represents
-
-    base64(<username>:<password>)

+# Working with Docker Images
+
+In the [introduction](/introduction/) we've discovered that Docker
+images are the basis of containers. In the
+[previous](/userguide/dockerizing/) [sections](/userguide/usingdocker/)
+we've used Docker images that already exist, for example the `ubuntu`
+image and the `training/webapp` image.
+
+We've also discovered that Docker stores downloaded images on the Docker
+host. If an image isn't already present on the host then it'll be
+downloaded from a registry: by default the
+[Docker.io](https://index.docker.io) public registry.
+
+In this section we're going to explore Docker images a bit more
+including:
+
+* Managing and working with images locally on your Docker host;
+* Creating basic images;
+* Uploading images to [Docker.io](https://index.docker.io).
+
+## Listing images on the host
+
+Let's start with listing the images we have locally on our host. You can
+do this using the `docker images` command like so:
+
+    $ sudo docker images
+    REPOSITORY       TAG      IMAGE ID      CREATED      VIRTUAL SIZE

+    ubuntu           lucid    3db9c44f4520  4 weeks ago  183 MB
+
+We can see the images we've previously used in our [user guide](/userguide/).
+Each has been downloaded from [Docker.io](https://index.docker.io) when we
+launched a container using that image.
+
+We can see three crucial pieces of information about our images in the listing.
+
+* What repository they came from, for example `ubuntu`.
+* The tags for each image, for example `14.04`.
+* The image ID of each image.
+
+A repository potentially holds multiple variants of an image. In the case of
+our `ubuntu` image we can see multiple variants covering Ubuntu 10.04, 12.04,
+12.10, 13.04, 13.10 and 14.04. Each variant is identified by a tag and you can
+refer to a tagged image like so:
+
+    ubuntu:14.04
+
+So when we run a container we refer to a tagged image like so:
+
+    $ sudo docker run -t -i ubuntu:14.04 /bin/bash
+
+If instead we wanted to build an Ubuntu 12.04 image we'd use:
+
+    $ sudo docker run -t -i ubuntu:12.04 /bin/bash
+
+If you don't specify a variant, for example you just use `ubuntu`, then Docker
+will default to using the `ubunut:latest` image.
+
+> **Tip:** 
+> We recommend you always use a specific tagged image, for example
+> `ubuntu:12.04`. That way you always know exactly what variant of an image is
+> being used.
+
+## Getting a new image
+
+So how do we get new images? Well Docker will automatically download any image
+we use that isn't already present on the Docker host. But this can potentially
+add some time to the launch of a container. If we want to pre-load an image we
+can download it using the `docker pull` command. Let's say we'd like to
+download the `centos` image.
+
+    $ sudo docker pull centos
+    Pulling repository centos
+    b7de3133ff98: Pulling dependent layers
+    5cc9e91966f7: Pulling fs layer
+    511136ea3c5a: Download complete
+    ef52fb1fe610: Download complete
+    . . .
+
+We can see that each layer of the image has been pulled down and now we
+can run a container from this image and we won't have to wait to
+download the image.
+
+    $ sudo docker run -t -i centos /bin/bash
+    bash-4.1#
+
+## Finding images
+
+One of the features of Docker is that a lot of people have created Docker
+images for a variety of purposes. Many of these have been uploaded to
+[Docker.io](https://index.docker.io). We can search these images on the
+[Docker.io](https://index.docker.io) website.
+
+![indexsearch](/userguide/search.png)
+
+We can also search for images on the command line using the `docker search`
+command. Let's say our team wants an image with Ruby and Sinatra installed on
+which to do our web application development. We can search for a suitable image
+by using the `docker search` command to find all the images that contain the
+term `sinatra`.
+
+    $ sudo docker search sinatra
+    NAME                                   DESCRIPTION                                     STARS     OFFICIAL   TRUSTED

+    luisbebop/docker-sinatra-hello-world                                                   0                    [OK]
+    bmorearty/handson-sinatra              handson-ruby + Sinatra for Hands on with D...   0
+    subwiz/sinatra                                                                         0
+    bmorearty/sinatra                                                                      0
+    . . .
+
+We can see we've returned a lot of images that use the term `sinatra`. We've
+returned a list of image names, descriptions, Stars (which measure the social
+popularity of images - if a user likes an image then they can "star" it), and
+the Official and Trusted statuses. Official repositories are XXX and Trusted
+repositories are [Trusted Build](/userguide/dockerrepos/) that allow you to
+validate the source and content of an image.
+
+We've reviewed the images available to use and we decided to use the
+`training/sinatra` image. So far we've seen two types of images repositories,
+images like `ubuntu`, which are called base or root images. These base images
+are provided by Docker Inc and are built, validated and supported. These can be
+identified by their single word names.
+
+We've also seen user images, for example the `training/sinatra` image we've
+chosen. A user image belongs to a member of the Docker community and is built
+and maintained by them.  You can identify user images as they are always
+prefixed with the user name, here `training`, of the user that created them.
+
+## Pulling our image
+
+We've identified a suitable image, `training/sinatra`, and now we can download it using the `docker pull` command.
+
+    $ sudo docker pull training/sinatra
+
+The team can now use this image by run their own containers.
+
+    $ sudo docker run -t -i training/sinatra /bin/bash
+    root@a8cb6ce02d85:/#
+
+## Creating our own images
+
+The team has found the `training/sinatra` image pretty useful but it's not quite what
+they need and we need to make some changes to it. There are two ways we can
+update and create images.
+
+1. We can update a container created from an image and commit the results to an image.
+2. We can use a `Dockerfile` to specify instructions to create an image.
+
+### Updating and committing an image
+
+To update an image we first need to create a container from the image
+we'd like to update.
+
+    $ sudo docker run -t -i training/sinatra /bin/bash
+    root@0b2616b0e5a8:/#
+
+> **Note:** 
+> Take note of the container ID that has been created, `0b2616b0e5a8`, as we'll
+> need it in a moment.
+
+Inside our running container let's add the `json` gem.
+
+    root@0b2616b0e5a8:/# gem install json
+
+Once this has completed let's exit our container using the `exit`
+command.
+
+Now we have a container with the change we want to make. We can then
+commit a copy of this container to an image using the `docker commit`
+command.
+
+    $ sudo docker commit -m="Added json gem" -a="Kate Smith" \
+    0b2616b0e5a8 ouruser/sinatra:v2
+    4f177bd27a9ff0f6dc2a830403925b5360bfe0b93d476f7fc3231110e7f71b1c
+
+Here we've used the `docker commit` command. We've specified two flags: `-m`
+and `-a`. The `-m` flag allows us to specify a commit message, much like you
+would with a commit on a version control system. The `-a` flag allows us to
+specify an author for our update.
+
+We've also specified the container we want to create this new image from,
+`0b2616b0e5a8` (the ID we recorded earlier) and we've specified a target for
+the image:
+
+    ouruser/sinatra:v2
+
+Let's break this target down. It consists of a new user, `ouruser`, that we're
+writing this image to. We've also specified the name of the image, here we're
+keeping the original image name `sinatra`. Finally we're specifying a tag for
+the image: `v2`.
+
+We can then look at our new `ouruser/sinatra` image using the `docker images`
+command.
+
+    $ sudo docker images
+    REPOSITORY          TAG     IMAGE ID       CREATED       VIRTUAL SIZE
+    training/sinatra    latest  5bc342fa0b91   10 hours ago  446.7 MB
+    ouruser/sinatra     v2      3c59e02ddd1a   10 hours ago  446.7 MB
+    ouruser/sinatra     latest  5db5f8471261   10 hours ago  446.7 MB
+
+To use our new image to create a container we can then:
+
+    $ sudo docker run -t -i ouruser/sinatra:v2 /bin/bash
+    root@78e82f680994:/#
+
+### Building an image from a `Dockerfile`
+
+Using the `docker commit` command is a pretty simple way of extending an image
+but it's a bit cumbersome and it's not easy to share a development process for
+images amongst a team. Instead we can use a new command, `docker build`, to
+build new images from scratch.
+
+To do this we create a `Dockerfile` that contains a set of instructions that
+tell Docker how to build our image.
+
+Let's create a directory and a `Dockerfile` first.
+
+    $ mkdir sinatra
+    $ cd sinatra
+    $ touch Dockerfile
+
+Each instructions creates a new layer of the image. Let's look at a simple
+example now for building our own Sinatra image for our development team.
+
+    # This is a comment
+    FROM ubuntu:14.04
+    MAINTAINER Kate Smith <ksmith@example.com>
+    RUN apt-get -qq update
+    RUN apt-get -qqy install ruby ruby-dev
+    RUN gem install sinatra
+
+Let's look at what our `Dockerfile` does. Each instruction prefixes a statement and is capitalized.
+
+    INSTRUCTION statement
+
+> **Note:**
+> We use `#` to indicate a comment
+
+The first instruction `FROM` tells Docker what the source of our image is, in
+this case we're basing our new image on an Ubuntu 14.04 image.
+
+Next we use the `MAINTAINER` instruction to specify who maintains our new image.
+
+Lastly, we've specified three `RUN` instructions. A `RUN` instruction executes
+a command inside the image, for example installing a package. Here we're
+updating our APT cache, installing Ruby and RubyGems and then installing the
+Sinatra gem.
+
+> **Note:** 
+> There are [a lot more instructions available to us in a Dockerfile](/reference/builder).
+
+Now let's take our `Dockerfile` and use the `docker build` command to build an image.
+
+    $ sudo docker build -t="ouruser/sinatra:v2" .

+     ---> 324104cde6ad
+    Removing intermediate container 5e9d0065c1f7
+    Successfully built 324104cde6ad
+
+We've specified our `docker build` command and used the `-t` flag to identify
+our new image as belonging to the user `ouruser`, the repository name `sinatra`
+and given it the tag `v2`.
+
+We've also specified the location of our `Dockerfile` using the `.` to
+indicate a `Dockerfile` in the current directory.
+
+> **Note::**
+> You can also specify a path to a `Dockerfile`.
+
+Now we can see the build process at work. The first thing Docker does is
+upload the build context: basically the contents of the directory you're
+building in. This is done because the Docker daemon does the actual
+build of the image and it needs the local context to do it.
+
+Next we can see each instruction in the `Dockerfile` being executed
+step-by-step. We can see that each step creates a new container, runs
+the instruction inside that container and then commits that change -
+just like the `docker commit` work flow we saw earlier. When all the
+instructions have executed we're left with the `324104cde6ad` image
+(also helpfully tagged as `ouruser/sinatra:v2`) and all intermediate
+containers will get removed to clean things up.
+
+We can then create a container from our new image.
+
+    $ sudo docker run -t -i ouruser/sinatra /bin/bash
+    root@8196968dac35:/#
+
+> **Note:** 
+> This is just the briefest introduction to creating images. We've
+> skipped a whole bunch of other instructions that you can use. We'll see more of
+> those instructions in later sections of the Guide or you can refer to the
+> [`Dockerfile`](/reference/builder/) reference for a
+> detailed description and examples of every instruction.
+
+## Setting tags on an image
+
+You can also add a tag to an existing image after you commit or build it. We
+can do this using the `docker tag` command. Let's add a new tag to our
+`ouruser/sinatra` image.
+
+    $ sudo docker tag 5db5f8471261 ouruser/sinatra:devel
+
+The `docker tag` command takes the ID of the image, here `5db5f8471261`, and our
+user name, the repository name and the new tag.
+
+Let's see our new tag using the `docker images` command.
+
+    $ sudo docker images ouruser/sinatra
+    REPOSITORY          TAG     IMAGE ID      CREATED        VIRTUAL SIZE
+    ouruser/sinatra     latest  5db5f8471261  11 hours ago   446.7 MB
+    ouruser/sinatra     devel   5db5f8471261  11 hours ago   446.7 MB
+    ouruser/sinatra     v2      5db5f8471261  11 hours ago   446.7 MB
+
+## Push an image to Docker.io
+
+Once you've built or created a new image you can push it to [Docker.io](
+https://index.docker.io) using the `docker push` command. This allows you to
+share it with others, either publicly, or push it into [a private
+repository](https://index.docker.io/plans/).
+
+    $ sudo docker push ouruser/sinatra
+    The push refers to a repository [ouruser/sinatra] (len: 1)
+    Sending image list
+    Pushing repository ouruser/sinatra (3 tags)
+    . . .
+
+## Remove an image from the host
+
+You can also remove images on your Docker host in a way [similar to
+containers](
+/userguide/usingdocker) using the `docker rmi` command.
+
+Let's delete the `training/sinatra` image as we don't need it anymore.
+
+    $ docker rmi training/sinatra
+    Untagged: training/sinatra:latest
+    Deleted: 5bc342fa0b91cabf65246837015197eecfa24b2213ed6a51a8974ae250fedd8d
+    Deleted: ed0fffdcdae5eb2c3a55549857a8be7fc8bc4241fb19ad714364cbfd7a56b22f
+    Deleted: 5c58979d73ae448df5af1d8142436d81116187a7633082650549c52c3a2418f0
+
+> **Note:** In order to remove an image from the host, please make sure
+> that there are no containers actively based on it.
+
+# Next steps
+
+Until now we've seen how to build individual applications inside Docker
+containers. Now learn how to build whole application stacks with Docker
+by linking together multiple Docker containers.

+# Getting Started with Docker.io
+
+*How do I use Docker.io?*
+
+In this section we're going to introduce you, very quickly!, to
+[Docker.io](https://index.docker.io) and create an account.
+
+[Docker.io](https://www.docker.io) is the central hub for Docker. It
+helps you to manage Docker and its components. It provides services such
+as:
+
+* Hosting images.
+* User authentication.
+* Automated image builds and work flow tools like build triggers and web
+  hooks.
+* Integration with GitHub and BitBucket.
+
+Docker.io helps you collaborate with colleagues and get the most out of
+Docker.
+
+In order to use Docker.io you will need to register an account. Don't
+panic! It's totally free and really easy.
+
+## Creating a Docker.io Account
+
+There are two ways you can create a Docker.io account:
+
+* Via the web, or
+* Via the command line.
+
+### Sign up via the web!
+
+Fill in the [sign-up form](https://www.docker.io/account/signup/) and
+choose your user name and specify some details such as an email address.
+
+![Register using the sign-up page](/userguide/register-web.png)
+
+### Signup via the command line
+
+You can also create a Docker.io account via the command line using the
+`docker login` command.
+
+    $ sudo docker login
+
+### Confirm your email
+
+Once you've filled in the form then check your email for a welcome
+message and activate your account.
+
+![Confirm your registration](/userguide/register-confirm.png)
+
+### Login!
+
+Then you can login using the web console:
+
+![Login using the web console](/userguide/login-web.png)
+
+Or via the command line and the `docker login` command:
+
+    $ sudo docker login
+
+Now your Docker.io account is active and ready for you to use!
+
+##  Next steps
+
+Now let's start Dockerizing applications with our "Hello World!" exercise.
+

+
+# Dockerizing Applications: A "Hello World!"
+
+*So what's this Docker thing all about?*
+
+Docker allows you to run applications inside containers. Running an
+application inside a container takes a single command: `docker run`.
+
+## Hello World!
+
+Let's try it now.
+
+    $ sudo docker run ubuntu:14.04 /bin/echo "Hello World!"
+    Hello World!
+
+And you just launched your first container!
+
+So what just happened? Let's step through what the `docker run` command
+did.
+
+First we specified the `docker` binary and the command we wanted to
+execute, `run`. The `docker run` combination *runs* containers.
+
+Next we specified an image: `ubuntu:14.04`. This is the source of the container
+we ran. Docker calls this an image. In this case we used an Ubuntu 14.04
+operating system image.
+
+When you specify an image, Docker looks first for the image on your
+Docker host. If it can't find it then it downloads the image from the public
+image registry: [Docker.io](https://index.docker.io).
+
+Next we told Docker what command to run inside our new container:
+
+    /bin/echo "Hello World!"
+
+When our container was launched Docker created a new Ubuntu 14.04
+environment and then executed the `/bin/echo` command inside it. We saw
+the result on the command line:
+
+    Hello World!
+
+So what happened to our container after that? Well Docker containers
+only run as long as the command you specify is active. Here, as soon as
+`Hello World!` was echoed, the container stopped.
+
+## An Interactive Container
+
+Let's try the `docker run` command again, this time specifying a new
+command to run in our container.
+
+    $ sudo docker run -t -i ubuntu:14.04 /bin/bash
+    root@af8bae53bdd3:/#
+
+Here we've again specified the `docker run` command and launched an
+`ubuntu:14.04` image. But we've also passed in two flags: `-t` and `-i`.
+The `-t` flag assigns a pseudo-tty or terminal inside our new container
+and the `-i` flag allows us to make an interactive connection by
+grabbing the standard in (`STDIN`) of the container.
+
+We've also specified a new command for our container to run:
+`/bin/bash`. This will launch a Bash shell inside our container.
+
+So now when our container is launched we can see that we've got a
+command prompt inside it:
+
+    root@af8bae53bdd3:/#
+
+Let's try running some commands inside our container:
+
+    root@af8bae53bdd3:/# pwd
+    /
+    root@af8bae53bdd3:/# ls
+    bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var
+
+You can see we've run the `pwd` to show our current directory and can
+see we're in the `/` root directory. We've also done a directory listing
+of the root directory which shows us what looks like a typical Linux
+file system.
+
+You can play around inside this container and when you're done you can
+use the `exit` command to finish.
+
+    root@af8bae53bdd3:/# exit
+
+As with our previous container, once the Bash shell process has
+finished, the container is stopped.
+
+## A Daemonized Hello World!
+
+Now a container that runs a command and then exits has some uses but
+it's not overly helpful. Let's create a container that runs as a daemon,
+like most of the applications we're probably going to run with Docker.
+
+Again we can do this with the `docker run` command:
+
+    $ sudo docker run -d ubuntu:14.04 /bin/sh -c "while true; do echo hello world; sleep 1; done"
+    1e5535038e285177d5214659a068137486f96ee5c2e85a4ac52dc83f2ebe4147
+
+Wait what? Where's our "Hello World!" Let's look at what we've run here.
+It should look pretty familiar. We ran `docker run` but this time we
+specified a flag: `-d`. The `-d` flag tells Docker to run the container
+and put it in the background, to daemonize it.
+
+We also specified the same image: `ubuntu:14.04`.
+
+Finally, we specified a command to run:
+
+    /bin/sh -c "while true; do echo hello world; sleep 1; done"
+
+This is the (hello) world's silliest daemon: a shell script that echoes
+`hello world` forever.
+
+So why aren't we seeing any `hello world`'s? Instead Docker has returned
+a really long string:
+
+    1e5535038e285177d5214659a068137486f96ee5c2e85a4ac52dc83f2ebe4147
+
+This really long string is called a *container ID*. It uniquely
+identifies a container so we can work with it.
+
+> **Note:** 
+> The container ID is a bit long and unwieldy and a bit later
+> on we'll see a shorter ID and some ways to name our containers to make
+> working with them easier.
+
+We can use this container ID to see what's happening with our `hello
+world` daemon.
+
+Firstly let's make sure our container is running. We can
+do that with the `docker ps` command. The `docker ps` command queries
+the Docker daemon for information about all the container it knows
+about.
+
+    $ docker ps
+    CONTAINER ID  IMAGE         COMMAND               CREATED        STATUS       PORTS NAMES
+    1e5535038e28  ubuntu:14.04  /bin/sh -c 'while tr  2 minutes ago  Up 1 minute        insane_babbage
+
+Here we can see our daemonized container. The `docker ps` has returned some useful
+information about it, starting with a shorter variant of its container ID:
+`1e5535038e28`.
+
+We can also see the image we used to build it, `ubuntu:14.04`, the command it
+is running, its status and an automatically assigned name,
+`insane_babbage`. 
+
+> **NoteL** 
+> Docker automatically names any containers you start, a
+> little later on we'll see how you can specify your own names.
+
+Okay, so we now know it's running. But is it doing what we asked it to do? To see this
+we're going to look inside the container using the `docker logs`
+command. Let's use the container name Docker assigned.
+
+    $ sudo docker logs insane_babbage
+    hello world
+    hello world
+    hello world
+    . . .
+
+The `docker logs` command looks inside the container and returns its standard
+output: in this case the output of our command `hello world`.
+
+Awesome! Our daemon is working and we've just created our first
+Dockerized application!
+
+Now we've established we can create our own containers let's tidy up
+after ourselves and stop our daemonized container. To do this we use the
+`docker stop` command.
+
+    $ sudo docker stop insane_babbage
+    insane_babbage
+
+The `docker stop` command tells Docker to politely stop the running
+container. If it succeeds it will return the name of the container it
+has just stopped.
+
+Let's check it worked with the `docker ps` command.
+
+    $ docker ps
+    CONTAINER ID  IMAGE         COMMAND               CREATED        STATUS       PORTS NAMES
+
+Excellent. Our container has been stopped.
+
+# Next steps
+
+Now we've seen how simple it is to get started with Docker let's learn how to
+do some more advanced tasks.

+
+# Linking Containers Together
+
+In [the Using Docker section](/userguide/usingdocker) we touched on
+connecting to a service running inside a Docker container via a network
+port. This is one of the ways that you can interact with services and
+applications running inside Docker containers. In this section we're
+going to give you a refresher on connecting to a Docker container via a
+network port as well as introduce you to the concepts of container
+linking.
+
+## Network port mapping refresher
+
+In [the Using Docker section](/userguide/usingdocker) we created a
+container that ran a Python Flask application.
+
+    $ sudo docker run -d -P training/webapp python app.py
+
+> **Note:** 
+> Containers have an internal network and an IP address
+> (remember we used the `docker inspect` command to show the container's
+> IP address in the [Using Docker](/userguide/usingdocker/) section).
+> Docker can have a variety of network configurations. You can see more
+> information on Docker networking [here](/articles/networking/).
+
+When we created that container we used the `-P` flag to automatically map any
+network ports inside that container to a random high port from the range 49000
+to 49900 on our Docker host.  When we subsequently ran `docker ps` we saw that
+port 5000 was bound to port 49155.
+
+    $ sudo docker ps nostalgic_morse
+    CONTAINER ID  IMAGE                   COMMAND       CREATED        STATUS        PORTS                    NAMES
+    bc533791f3f5  training/webapp:latest  python app.py 5 seconds ago  Up 2 seconds  0.0.0.0:49155->5000/tcp  nostalgic_morse
+
+We also saw how we can bind a container's ports to a specific port using
+the `-p` flag.
+
+    $ sudo docker run -d -p 5000:5000 training/webapp python app.py
+
+And we saw why this isn't such a great idea because it constrains us to
+only one container on that specific port.
+
+There are also a few other ways we can configure the `-p` flag. By
+default the `-p` flag will bind the specified port to all interfaces on
+the host machine. But we can also specify a binding to a specific
+interface, for example only to the `localhost`.
+
+    $ sudo docker run -d -p 127.0.0.1:5000:5000 training/webapp python app.py
+
+This would bind port 5000 inside the container to port 5000 on the
+`localhost` or `127.0.0.1` interface on the host machine.
+
+Or to bind port 5000 of the container to a dynamic port but only on the
+`localhost` we could:
+
+    $ sudo docker run -d -p 127.0.0.1::5000 training/webapp python app.py
+
+We can also bind UDP ports by adding a trailing `/udp`, for example:
+
+    $ sudo docker run -d -p 127.0.0.1:5000:5000/udp training/webapp python app.py
+
+We also saw the useful `docker port` shortcut which showed us the
+current port bindings, this is also useful for showing us specific port
+configurations. For example if we've bound the container port to the
+`localhost` on the host machine this will be shown in the `docker port`
+output.
+
+    $ docker port nostalgic_morse
+    127.0.0.1:49155
+
+> **Note:** 
+> The `-p` flag can be used multiple times to configure multiple ports.
+
+## Docker Container Linking
+
+Network port mappings are not the only way Docker containers can connect
+to one another. Docker also has a linking system that allows you to link
+multiple containers together and share connection information between
+them. Docker linking will create a parent child relationship where the
+parent container can see selected information about its child.
+
+## Container naming
+
+To perform this linking Docker relies on the names of your containers.
+We've already seen that each container we create has an automatically
+created name, indeed we've become familiar with our old friend
+`nostalgic_morse` during this guide. You can also name containers
+yourself. This naming provides two useful functions:
+
+1. It's useful to name containers that do specific functions in a way
+   that makes it easier for you to remember them, for example naming a
+   container with a web application in it `web`.
+
+2. It provides Docker with reference point that allows it to refer to other
+   containers, for example link container `web` to container `db`.
+
+You can name your container by using the `--name` flag, for example:
+
+    $ sudo docker run -d -P --name web training/webapp python app.py
+
+You can see we've launched a new container and used the `--name` flag to
+call the container `web`. We can see the container's name using the
+`docker ps` command.
+
+    $ sudo docker ps -l
+    CONTAINER ID  IMAGE                  COMMAND        CREATED       STATUS       PORTS                    NAMES
+    aed84ee21bde  training/webapp:latest python app.py  12 hours ago  Up 2 seconds 0.0.0.0:49154->5000/tcp  web
+
+We can also use `docker inspect` to return the container's name.
+
+    $ sudo docker inspect -f "{{ .Name }}" aed84ee21bde
+    /web
+
+> **Note:** 
+> Container names have to be unique. That means you can only call
+> one container `web`. If you want to re-use a container name you must delete the
+> old container with the `docker rm` command before you can create a new
+> container with the same name. As an alternative you can use the `--rm`
+> flag with the `docker run` command. This will delete the container
+> immediately after it stops.
+
+## Container Linking
+
+Links allow containers to discover and securely communicate with each
+other. To create a link you use the `--link` flag. Let's create a new
+container, this one a database.
+
+    $ sudo docker run -d --name db training/postgres
+
+Here we've created a new container called `db` using the `training/postgres`
+image, which contains a PostgreSQL database.
+
+Now let's create a new `web` container and link it with our `db` container.
+
+    $ sudo docker run -d -P --name web --link db:db training/webapp python app.py
+
+This will link the new `web` container with the `db` container we created
+earlier. The `--link` flag takes the form:
+
+    --link name:alias
+
+Where `name` is the name of the container we're linking to and `alias` is an
+alias for the link name. We'll see how that alias gets used shortly.
+
+Let's look at our linked containers using `docker ps`.
+
+    $ docker ps
+    CONTAINER ID  IMAGE                     COMMAND               CREATED             STATUS             PORTS                    NAMES
+    349169744e49  training/postgres:latest  su postgres -c '/usr  About a minute ago  Up About a minute  5432/tcp                 db
+    aed84ee21bde  training/webapp:latest    python app.py         16 hours ago        Up 2 minutes       0.0.0.0:49154->5000/tcp  db/web,web
+
+We can see our named containers, `db` and `web`, and we can see that the `web`
+containers also shows `db/web` in the `NAMES` column. This tells us that the
+`web` container is linked to the `db` container in a parent/child relationship.
+
+So what does linking the containers do? Well we've discovered the link creates
+a parent-child relationship between the two containers. The parent container,
+here `db`, can access information on the child container `web`. To do this
+Docker creates a secure tunnel between the containers without the need to
+expose any ports externally on the container. You'll note when we started the
+`db` container we did not use either of the `-P` or `-p` flags. As we're
+linking the containers we don't need to expose the PostgreSQL database via the
+network.
+
+Docker exposes connectivity information for the parent container inside the
+child container in two ways:
+
+* Environment variables,
+* Updating the `/etc/host` file.
+
+Let's look first at the environment variables Docker sets. Inside the `web`
+container let's run the `env` command to list the container's environment
+variables.
+
+    root@aed84ee21bde:/opt/webapp# env
+    HOSTNAME=aed84ee21bde
+    . . .
+    DB_NAME=/web/db
+    DB_PORT=tcp://172.17.0.5:5432
+    DB_PORT_5000_TCP=tcp://172.17.0.5:5432
+    DB_PORT_5000_TCP_PROTO=tcp
+    DB_PORT_5000_TCP_PORT=5432
+    DB_PORT_5000_TCP_ADDR=172.17.0.5
+    . . .
+
+> **Note**:
+> These Environment variables are only set for the first process in the
+> container. Similarly, some daemons (such as `sshd`)
+> will scrub them when spawning shells for connection.
+
+We can see that Docker has created a series of environment variables with
+useful information about our `db` container. Each variables is prefixed with
+`DB` which is populated from the `alias` we specified above. If our `alias`
+were `db1` the variables would be prefixed with `DB1_`. You can use these
+environment variables to configure your applications to connect to the database
+on the `db` container. The connection will be secure, private and only the
+linked `web` container will be able to talk to the `db` container.
+
+In addition to the environment variables Docker adds a host entry for the
+linked parent to the `/etc/hosts` file. Let's look at this file on the `web`
+container now.
+
+    root@aed84ee21bde:/opt/webapp# cat /etc/hosts
+    172.17.0.7  aed84ee21bde
+    . . .
+    172.17.0.5  db
+
+We can see two relevant host entries. The first is an entry for the `web`
+container that uses the Container ID as a host name. The second entry uses the
+link alias to reference the IP address of the `db` container. Let's try to ping
+that host now via this host name.
+
+    root@aed84ee21bde:/opt/webapp# apt-get install -yqq inetutils-ping
+    root@aed84ee21bde:/opt/webapp# ping db
+    PING db (172.17.0.5): 48 data bytes
+    56 bytes from 172.17.0.5: icmp_seq=0 ttl=64 time=0.267 ms
+    56 bytes from 172.17.0.5: icmp_seq=1 ttl=64 time=0.250 ms
+    56 bytes from 172.17.0.5: icmp_seq=2 ttl=64 time=0.256 ms
+
+> **Note:** 
+> We had to install `ping` because our container didn't have it.
+
+We've used the `ping` command to ping the `db` container using it's host entry
+which resolves to `172.17.0.5`. We can make use of this host entry to configure
+an application to make use of our `db` container.
+
+> **Note:** 
+> You can link multiple child containers to a single parent. For
+> example, we could have multiple web containers attached to our `db`
+> container.
+
+# Next step
+
+Now we know how to link Docker containers together the next step is
+learning how to manage data, volumes and mounts inside our containers.

+page_description: Learning how to use Docker.io to manage images and work flow
+page_keywords: repo, Docker.io, Docker Hub, registry, index, repositories, usage, pull image, push image, image, documentation
+
+# Working with Docker.io
+
+So far we've seen a lot about how to use Docker on the command line and
+your local host. We've seen [how to pull down
+images](/userguide/usingdocker/) that you can run your containers from
+and we've seen how to [create your own images](/userguide/dockerimages).
+
+Now we're going to learn a bit more about
+[Docker.io](https://index.docker.io) and how you can use it to enhance
+your Docker work flows.
+
+[Docker.io](https://index.docker.io) is the public registry that Docker
+Inc maintains. It contains a huge collection of images, over 15,000,
+that you can download and use to build your containers. It also provides
+authentication, structure (you can setup teams and organizations), work
+flow tools like webhooks and build triggers as well as privacy features
+like private repositories for storing images you don't want to publicly
+share.
+
+## Docker commands and Docker.io
+
+Docker acts as a client for these services via the `docker search`,
+`pull`, `login` and `push` commands.
+
+## Searching for images
+
+As we've already seen we can search the
+[Docker.io](https://index.docker.io) registry via it's search interface
+or using the command line interface. Searching can find images by name,
+user name or description:
+
+    $ sudo docker search centos
+    NAME           DESCRIPTION                                     STARS     OFFICIAL   TRUSTED
+    centos         Official CentOS 6 Image as of 12 April 2014     88
+    tianon/centos  CentOS 5 and 6, created using rinse instea...   21
+    ...
+
+There you can see two example results: `centos` and
+`tianon/centos`. The second result shows that it comes from
+the public repository of a user, `tianon/`, while the first result,
+`centos`, doesn't explicitly list a repository so it comes from the
+trusted top-level namespace. The `/` character separates a user's
+repository and the image name.
+
+Once you have found the image you want, you can download it:
+
+    $ sudo docker pull centos
+    Pulling repository centos
+    0b443ba03958: Download complete
+    539c0211cd76: Download complete
+    511136ea3c5a: Download complete
+    7064731afe90: Download complete
+
+The image is now available to run a container from.
+
+## Contributing to Docker.io
+
+Anyone can pull public images from the [Docker.io](http://index.docker.io)
+registry, but if you would like to share your own images, then you must
+register a user first as we saw in the [first section of the Docker User
+Guide](/userguide/dockerio/).
+
+To refresh your memory, you can create your user name and login to
+[Docker.io](https://index.docker.io/account/signup/), or by running:
+
+    $ sudo docker login
+
+This will prompt you for a user name, which will become a public
+namespace for your public repositories, for example:
+
+    training/webapp
+
+Here `training` is the user name and `webapp` is a repository owned by
+that user.
+
+If your user name is available then `docker` will also prompt you to
+enter a password and your e-mail address. It will then automatically log
+you in. Now you're ready to commit and push your own images!
+
+> **Note:**
+> Your authentication credentials will be stored in the [`.dockercfg`
+> authentication file](#authentication-file) in your home directory.
+
+## Pushing a repository to Docker.io
+
+In order to push an repository to its registry you need to have named an image,
+or committed your container to a named image as we saw
+[here](/userguide/dockerimages).
+
+Now you can push this repository to the registry designated by its name
+or tag.
+
+    $ sudo docker push yourname/newimage
+
+The image will then be uploaded and available for use.
+
+## Features of Docker.io
+
+Now let's look at some of the features of Docker.io. You can find more
+information [here](/docker-io/).
+
+* Private repositories
+* Organizations and teams
+* Automated Builds
+* Webhooks
+
+## Private Repositories
+
+Sometimes you have images you don't want to make public and share with
+everyone. So Docker.io allows you to have private repositories. You can
+sign up for a plan [here](https://index.docker.io/plans/).
+
+## Organizations and teams
+
+One of the useful aspects of private repositories is that you can share
+them only with members of your organization or team. Docker.io lets you
+create organizations where you can collaborate with your colleagues and
+manage private repositories. You can create and manage an organization
+[here](https://index.docker.io/account/organizations/).
+
+## Automated Builds
+
+Automated Builds automate the building and updating of images from [GitHub](https://www.github.com)
+or [BitBucket](http://bitbucket.com), directly on Docker.io. It works by adding a commit hook to
+your selected GitHub or BitBucket repository, triggering a build and update when you push a
+commit.
+
+### To setup an Automated Build
+
+1.  Create a [Docker.io account](https://index.docker.io/) and login.
+2.  Link your GitHub or BitBucket account through the [`Link Accounts`](https://index.docker.io/account/accounts/) menu.
+3.  [Configure an Automated Build](https://index.docker.io/builds/).
+4.  Pick a GitHub or BitBucket project that has a `Dockerfile` that you want to build.
+5.  Pick the branch you want to build (the default is the `master` branch).
+6.  Give the Automated Build a name.
+7.  Assign an optional Docker tag to the Build.
+8.  Specify where the `Dockerfile` is located. The default is `/`.
+
+Once the Automated Build is configured it will automatically trigger a
+build, and in a few minutes, if there are no errors, you will see your
+new Automated Build on the [Docker.io](https://index.docker.io) Registry.
+It will stay in sync with your GitHub and BitBucket repository until you
+deactivate the Automated Build.
+
+If you want to see the status of your Automated Builds you can go to your
+[Automated Builds page](https://index.docker.io/builds/) on the Docker.io,
+and it will show you the status of your builds, and the build history.
+
+Once you've created an Automated Build you can deactivate or delete it. You
+cannot however push to an Automated Build with the `docker push` command.
+You can only manage it by committing code to your GitHub or BitBucket
+repository.
+
+You can create multiple Automated Builds per repository and configure them
+to point to specific `Dockerfile`'s or Git branches.
+
+### Build Triggers
+
+Automated Builds can also be triggered via a URL on Docker.io. This
+allows you to rebuild an Automated build image on demand.
+
+## Webhooks
+
+Webhooks are attached to your repositories and allow you to trigger an
+event when an image or updated image is pushed to the repository. With
+a webhook you can specify a target URL and a JSON payload will be
+delivered when the image is pushed.
+
+## Next steps
+
+Go and use Docker!

+page_title: Managing Data in Containers
+page_description: How to manage data inside your Docker containers.
+page_keywords: Examples, Usage, volume, docker, documentation, user guide, data, volumes
+
+# Managing Data in Containers
+
+So far we've been introduced some [basic Docker
+concepts](/userguide/usingdocker/), seen how to work with [Docker
+images](/userguide/dockerimages/) as well as learned about [networking
+and links between containers](/userguide/dockerlinks/). In this section
+we're going to discuss how you can manage data inside and between your
+Docker containers.
+
+We're going to look at the two primary ways you can manage data in
+Docker.
+
+* Data volumes, and
+* Data volume containers.
+
+## Data volumes
+
+A *data volume* is a specially-designated directory within one or more
+containers that bypasses the [*Union File
+System*](/terms/layer/#ufs-def) to provide several useful features for
+persistent or shared data:
+
+- Data volumes can be shared and reused between containers
+- Changes to a data volume are made directly
+- Changes to a data volume will not be included when you update an image
+- Volumes persist until no containers use them
+
+### Adding a data volume
+
+You can add a data volume to a container using the `-v` flag with the
+`docker run` command. You can use the `-v` multiple times in a single
+`docker run` to mount multiple data volumes. Let's mount a single volume
+now in our web application container.
+
+    $ sudo docker run -d -P --name web -v /webapp training/webapp python app.py
+
+This will create a new volume inside a container at `/webapp`.
+
+> **Note:** 
+> You can also use the `VOLUME` instruction in a `Dockerfile` to add one or
+> more new volumes to any container created from that image.
+
+### Mount a Host Directory as a Data Volume
+
+In addition to creating a volume using the `-v` flag you can also mount a
+directory from your own host into a container.
+
+    $ sudo docker run -d -P --name web -v /src/webapp:/opt/webapp training/webapp python app.py
+
+This will mount the local directory, `/src/webapp`, into the container as the
+`/opt/webapp` directory. This is very useful for testing, for example we can
+mount our source code inside the container and see our application at work as
+we change the source code. The directory on the host must be specified as an
+absolute path and if the directory doesn't exist Docker will automatically
+create it for you.
+
+> **Note::** 
+> This is not available from a `Dockerfile` due the portability
+> and sharing purpose of it. As the host directory is, by its nature,
+> host-dependent it might not work all hosts.
+
+Docker defaults to a read-write volume but we can also mount a directory
+read-only.
+
+    $ sudo docker run -d -P --name web -v /src/webapp:/opt/webapp:ro training/webapp python app.py
+
+Here we've mounted the same `/src/webapp` directory but we've added the `ro`
+option to specify that the mount should be read-only.
+
+## Creating and mounting a Data Volume Container
+
+If you have some persistent data that you want to share between
+containers, or want to use from non-persistent containers, it's best to
+create a named Data Volume Container, and then to mount the data from
+it.
+
+Let's create a new named container with a volume to share.
+
+    $ docker run -d -v /dbdata --name dbdata training/postgres
+
+You can then use the `--volumes-from` flag to mount the `/dbdata` volume in another container.
+
+    $ docker run -d --volumes-from dbdata --name db1 training/postgres
+
+And another:
+
+    $ docker run -d --volumes-from dbdata --name db2 training/postgres
+
+You can use multiple `-volumes-from` parameters to bring together multiple data
+volumes from multiple containers.
+
+You can also extend the chain by mounting the volume that came from the
+`dbdata` container in yet another container via the `db1` or `db2` containers.
+
+    $ docker run -d --name db3 --volumes-from db1 training/postgres
+
+If you remove containers that mount volumes, including the initial `dbdata`
+container, or the subsequent containers `db1` and `db2`, the volumes will not
+be deleted until there are no containers still referencing those volumes. This
+allows you to upgrade, or effectively migrate data volumes between containers.
+
+## Backup, restore, or migrate data volumes
+
+Another useful function we can perform with volumes is use them for
+backups, restores or migrations.  We do this by using the
+`--volumes-from` flag to create a new container that mounts that volume,
+like so:
+
+    $ sudo docker run --volumes-from dbdata -v $(pwd):/backup ubuntu tar cvf /backup/backup.tar /dbdata
+
+Here's we've launched a new container and mounted the volume from the
+`dbdata` container. We've then mounted a local host directory as
+`/backup`. Finally, we've passed a command that uses `tar` to backup the
+contents of the `dbdata` volume to a `backup.tar` file inside our
+`/backup` directory. When the command completes and the container stops
+we'll be left with a backup of our `dbdata` volume.
+
+You could then to restore to the same container, or another that you've made
+elsewhere. Create a new container.
+
+    $ sudo docker run -v /dbdata --name dbdata2 ubuntu
+
+Then un-tar the backup file in the new container's data volume.
+
+    $ sudo docker run --volumes-from dbdata2 -v $(pwd):/backup busybox tar xvf /backup/backup.tar
+
+You can use this techniques above to automate backup, migration and
+restore testing using your preferred tools.
+
+# Next steps
+

+# Welcome to the Docker User Guide
+
+In the [Introduction](/) you got a taste of what Docker is and how it
+works. In this guide we're going to take you through the fundamentals of
+using Docker and integrating it into your environment.
+
+We’ll teach you how to use Docker to:
+
+* Dockerizing your applications.
+* Run your own containers.
+* Build Docker images.
+* Share your Docker images with others.
+* And a whole lot more!
+
+We've broken this guide into major sections that take you through
+the Docker life cycle:
+
+## Getting Started with Docker.io
+
+*How do I use Docker.io?*
+
+Docker.io is the central hub for Docker. It hosts public Docker images
+and provides services to help you build and manage your Docker
+environment. To learn more;
+
+Go to [Using Docker.io](/userguide/dockerio).
+
+## Dockerizing Applications: A "Hello World!"
+
+*How do I run applications inside containers?*
+
+Docker offers a *container-based* virtualization platform to power your
+applications. To learn how to Dockerize applications and run them.
+
+Go to [Dockerizing Applications](/userguide/dockerizing).
+
+## Working with Containers
+
+*How do I manage my containers?*
+
+Once you get a grip on running your applications in Docker containers
+we're going to show you how to manage those containers. To find out
+about how to inspect, monitor and manage containers:
+
+Go to [Working With Containers](/userguide/usingdocker).
+
+## Working with Docker Images
+
+*How can I access, share and build my own images?*
+
+Once you've learnt how to use Docker it's time to take the next step and
+learn how to build your own application images with Docker.
+
+Go to [Working with Docker Images](/userguide/dockerimages)
+
+## Linking Containers Together
+
+Until now we've seen how to build individual applications inside Docker
+containers. Now learn how to build whole application stacks with Docker
+by linking together multiple Docker containers.
+
+Go to [Linking Containers Together](/userguide/dockerlinks).
+
+## Managing Data in Containers
+
+Now we know how to link Docker containers together the next step is
+learning how to manage data, volumes and mounts inside our containers.
+
+Go to [Managing Data in Containers](/userguide/dockervolumes).
+
+## Working with Docker.io
+
+Now we've learned a bit more about how to use Docker we're going to see
+how to combine Docker with the services available on Docker.io including
+Trusted Builds and private repositories.
+
+Go to [Working with Docker.io](/userguide/dockerrepos).

+
+# Working with Containers
+
+In the [last section of the Docker User Guide](/userguide/dockerizing)
+we launched our first containers. We launched two containers using the
+`docker run` command.
+
+* Containers we ran interactively in the foreground.
+* One container we ran daemonized in the background.
+
+In the process we learned about several Docker commands:
+
+* `docker ps` - Lists containers.
+* `docker logs` - Shows us the standard output of a container.
+* `docker stop` - Stops running containers.
+
+> **Tip:**
+> Another way to learn about `docker` commands is our
+> [interactive tutorial](https://www.docker.io/gettingstarted).
+
+The `docker` client is pretty simple. Each action you can take
+with Docker is a command and each command can take a series of
+flags and arguments.
+
+    # Usage:  [sudo] docker [flags] [command] [arguments] ..
+    # Example:
+    $ docker run -i -t ubuntu /bin/bash
+
+Let's see this in action by using the `docker version` command to return
+version information on the currently installed Docker client and daemon.
+
+    $ sudo docker version
+
+This command will not only provide you the version of Docker client and
+daemon you are using, but also the version of Go (the programming
+language powering Docker).
+
+    Client version: 0.8.0
+    Go version (client): go1.2
+
+    Git commit (client): cc3a8c8
+    Server version: 0.8.0
+
+    Git commit (server): cc3a8c8
+    Go version (server): go1.2
+
+    Last stable version: 0.8.0
+
+### Seeing what the Docker client can do
+
+We can see all of the commands available to us with the Docker client by
+running the `docker` binary without any options.
+
+    $ sudo docker
+
+You will see a list of all currently available commands.
+
+    Commands:
+         attach    Attach to a running container
+         build     Build an image from a Dockerfile
+         commit    Create a new image from a container's changes
+    . . .
+
+### Seeing Docker command usage
+
+You can also zoom in and review the usage for specific Docker commands.
+
+Try typing Docker followed with a `[command]` to see the usage for that
+command:
+
+    $ sudo docker attach
+    Help output . . .
+
+Or you can also pass the `--help` flag to the `docker` binary.
+
+    $ sudo docker images --help
+
+This will display the help text and all available flags:
+
+    Usage: docker attach [OPTIONS] CONTAINER
+
+    Attach to a running container
+
+      --no-stdin=false: Do not attach stdin
+      --sig-proxy=true: Proxify all received signal to the process (even in non-tty mode)
+
+
+None of the containers we've run did anything particularly useful
+though. So let's build on that experience by running an example web
+application in Docker.
+
+> **Note:** 
+> You can see a full list of Docker's commands
+> [here](/reference/commandline/cli/).
+
+## Running a Web Application in Docker
+
+So now we've learnt a bit more about the `docker` client let's move onto
+the important stuff: running more containers. So far none of the
+containers we've run did anything particularly useful though. So let's
+build on that experience by running an example web application in
+Docker.
+
+For our web application we're going to run a Python Flask application.
+Let's start with a `docker run` command.
+
+    $ sudo docker run -d -P training/webapp python app.py
+
+Let's review what our command did. We've specified two flags: `-d` and
+`-P`. We've already seen the `-d` flag which tells Docker to run the
+container in the background. The `-P` flag is new and tells Docker to
+map any required network ports inside our container to our host. This
+lets us view our web application.
+
+We've specified an image: `training/webapp`. This image is a
+pre-built image we've created that contains a simple Python Flask web
+application.
+
+Lastly, we've specified a command for our container to run: `python
+app.py`. This launches our web application.
+
+> **Note:** 
+> You can see more detail on the `docker run` command in the [command
+> reference](/reference/commandline/cli/#run) and the [Docker Run
+> Reference](/reference/run/).
+
+## Viewing our Web Application Container
+
+Now let's see our running container using the `docker ps` command.
+
+    $ sudo docker ps -l
+    CONTAINER ID  IMAGE                   COMMAND       CREATED        STATUS        PORTS                    NAMES
+    bc533791f3f5  training/webapp:latest  python app.py 5 seconds ago  Up 2 seconds  0.0.0.0:49155->5000/tcp  nostalgic_morse
+
+You can see we've specified a new flag, `-l`, for the `docker ps`
+command. This tells the `docker ps` command to return the details of the
+*last* container started.
+
+> **Note:** 
+> The `docker ps` command only shows running containers. If you want to
+> see stopped containers too use the `-a` flag.
+
+We can see the same details we saw [when we first Dockerized a
+container](/userguide/dockerizing) with one important addition in the `PORTS`
+column.
+
+    PORTS
+    0.0.0.0:49155->5000/tcp
+
+When we passed the `-P` flag to the `docker run` command Docker mapped any
+ports exposed in our image to our host.
+
+> **Note:** 
+> We'll learn more about how to expose ports in Docker images when
+> [we learn how to build images](/userguide/dockerimages).
+
+In this case Docker has exposed port 5000 (the default Python Flask
+port) on port 49155.
+
+Network port bindings are very configurable in Docker. In our last
+example the `-P` flag is a shortcut for `-p 5000` that makes port 5000
+inside the container to a high port (from the range 49000 to 49900) on
+the local Docker host. We can also bind Docker container's to specific
+ports using the `-p` flag, for example:
+
+    $ sudo docker run -d -p 5000:5000 training/webapp python app.py
+
+This would map port 5000 inside our container to port 5000 on our local
+host. You might be asking about now: why wouldn't we just want to always
+use 1:1 port mappings in Docker containers rather than mapping to high
+ports? Well 1:1 mappings have the constraint of only being able to map
+one of each port on your local host. Let's say you want to test two
+Python applications: both bound to port 5000 inside your container.
+Without Docker's port mapping you could only access one at a time.
+
+So let's now browse to port 49155 in a web browser to
+see the application.
+
+![Viewing the web application](/userguide/webapp1.png).
+
+Our Python application is live!
+
+## A Network Port Shortcut
+
+Using the `docker ps` command to return the mapped port is a bit clumsy so
+Docker has a useful shortcut we can use: `docker port`. To use `docker port` we
+specify the ID or name of our container and then the port for which we need the
+corresponding public-facing port.
+
+    $ sudo docker port nostalgic_morse 5000
+    0.0.0.0:49155
+
+In this case we've looked up what port is mapped externally to port 5000 inside
+the container.
+
+## Viewing the Web Application's Logs
+
+Let's also find out a bit more about what's happening with our application and
+use another of the commands we've learnt, `docker logs`.
+
+    $ sudo docker logs -f nostalgic_morse
+    * Running on http://0.0.0.0:5000/
+    10.0.2.2 - - [23/May/2014 20:16:31] "GET / HTTP/1.1" 200 -
+    10.0.2.2 - - [23/May/2014 20:16:31] "GET /favicon.ico HTTP/1.1" 404 -
+
+This time though we've added a new flag, `-f`. This causes the `docker
+logs` command to act like the `tail -f` command and watch the
+container's standard out. We can see here the logs from Flask showing
+the application running on port 5000 and the access log entries for it.
+
+## Looking at our Web Application Container's processes
+
+In addition to the container's logs we can also examine the processes
+running inside it using the `docker top` command.
+
+    $ sudo docker top nostalgic_morse
+    PID                 USER                COMMAND
+    854                 root                python app.py
+
+Here we can see our `python app.py` command is the only process running inside
+the container.
+
+## Inspecting our Web Application Container
+
+Lastly, we can take a low-level dive into our Docker container using the
+`docker inspect` command. It returns a JSON hash of useful configuration
+and status information about Docker containers.
+
+    $ docker inspect nostalgic_morse
+
+Let's see a sample of that JSON output.
+
+    [{
+        "ID": "bc533791f3f500b280a9626688bc79e342e3ea0d528efe3a86a51ecb28ea20",
+        "Created": "2014-05-26T05:52:40.808952951Z",
+        "Path": "python",
+        "Args": [
+           "app.py"
+        ],
+        "Config": {
+           "Hostname": "bc533791f3f5",
+           "Domainname": "",
+           "User": "",
+    . . .
+
+We can also narrow down the information we want to return by requesting a
+specific element, for example to return the container's IP address we would:
+
+    $ sudo docker inspect -f '{{ .NetworkSettings.IPAddress }}'
+    172.17.0.5
+
+## Stopping our Web Application Container
+
+Okay we've seen web application working. Now let's stop it using the
+`docker stop` command and the name of our container: `nostalgic_morse`.
+
+    $ sudo docker stop nostalgic_morse
+    nostalgic_morse
+
+We can now use the `docker ps` command to check if the container has
+been stopped.
+
+    $ sudo docker ps -l
+
+## Restarting our Web Application Container
+
+Oops! Just after you stopped the container you get a call to say another
+developer needs the container back. From here you have two choices: you
+can create a new container or restart the old one. Let's look at
+starting our previous container back up.
+
+    $ sudo docker start nostalgic_morse
+    nostalgic_morse
+
+Now quickly run `docker ps -l` again to see the running container is
+back up or browse to the container's URL to see if the application
+responds.
+
+> **Note:** 
+> Also available is the `docker restart` command that runs a stop and
+> then start on the container.
+
+## Removing our Web Application Container
+
+Your colleague has let you know that they've now finished with the container
+and won't need it again. So let's remove it using the `docker rm` command.
+
+    $ sudo docker rm nostalgic_morse
+    Error: Impossible to remove a running container, please stop it first or use -f
+    2014/05/24 08:12:56 Error: failed to remove one or more containers
+
+What's happened? We can't actually remove a running container. This protects
+you from accidentally removing a running container you might need. Let's try
+this again by stopping the container first.
+
+    $ sudo docker stop nostalgic_morse
+    nostalgic_morse
+    $ sudo docker rm nostalgic_morse
+    nostalgic_morse
+
+And now our container is stopped and deleted.
+
+> **Note:**
+> Always remember that deleting a container is final!
+
+# Next steps
+
+Until now we've only used images that we've downloaded from
+[Docker.io](https://index.docker.io) now let's get introduced to
+building and sharing our own images.
+
+Go to [Working with Docker Images](/userguide/dockerimages).
