page_title: Docker Hub Enterprise: Admin guide
page_description: Documentation describing administration of Docker Hub Enterprise
page_keywords: docker, documentation, about, technology, hub, enterprise
# Docker Hub Enterprise Administrator's Guide
This guide covers tasks and functions an administrator of Docker Hub Enterprise
(DHE) will need to know about, such as reporting, logging, system management,
performance metrics, etc.
For tasks DHE users need to accomplish, such as using DHE to push and pull
images, please visit the [User's Guide](./userguide).
## Reporting
### System Health
![System Health page</admin/metrics/>](../assets/admin-metrics.png)
The "System Health" tab displays resource utilization metrics for the DHE host
as well as for each of its contained services. The CPU and RAM usage meters at
the top indicate overall resource usage for the host, while detailed time-series
charts are provided below for each service. You can mouse-over the charts or
meters to see detailed data points.
Clicking on a service name (i.e., "load_balancer", "admin_server", etc.) will
display the network, CPU, and memory (RAM) utilization data for the specified
service. See below for a
[detailed explanation of the available services](#services).
### Logs
![System Logs page</admin/logs/>](../assets/admin-logs.png)
Click the "Logs" tab to view all logs related to your DHE instance. You will see
log sections on this page for each service in your DHE instance. Older or newer
logs can be loaded by scrolling up or down. See below for a
[detailed explanation of the available services](#services).
DHE's log files can be found on the host in `/usr/local/etc/dhe/logs/`. The
files are limited to a maximum size of 64mb. They are rotated every two weeks,
when the aggregator sends logs to the collection server, or they are rotated if
a logfile would exceed 64mb without rotation. Log files are named `<component
name>-<timestamp at rotation>`, where the "component name" is the service it
provides (`manager`, `admin-server`, etc.).
### Usage statistics and crash reports
During normal use, DHE generates usage statistics and crash reports. This
information is collected by Docker, Inc. to help us prioritize features, fix
bugs, and improve our products. Specifically, Docker, Inc. collects the
following information:
* Error logs
* Crash logs
## Emergency access to the DHE admin web interface
If your authenticated or public access to the DHE web interface has stopped
working, but your DHE admin container is still running, you can add an
[ambassador container](https://docs.docker.com/articles/ambassador_pattern_linking/)
to get temporary unsecure access to it by running:
$ docker run --rm -it --link docker_hub_enterprise_admin_server:admin -p 9999:80 svendowideit/ambassador
> **Note:** This guide assumes you can run Docker commands from a machine where
> you are a member of the `docker` group, or have root privileges. Otherwise,
> you may need to add `sudo` to the example command above.
This will give you access on port `9999` on your DHE server - `http://<dhe-host-ip>:9999/admin/`.
## Services
DHE runs several Docker services which are essential to its reliability and
usability. The following services are included; you can see their details by
running queries on the [System Health](#system-health) and [Logs](#logs) pages:
* `admin_server`: Used for displaying system health, performing upgrades,
configuring settings, and viewing logs.
* `load_balancer`: Used for maintaining high availability by distributing load
to each image storage service (`image_storage_X`).
* `log_aggregator`: A microservice used for aggregating logs from each of the
other services. Handles log persistence and rotation on disk.
* `image_storage_X`: Stores Docker images using the [Docker Registry HTTP API V2](https://github.com/docker/distribution/blob/master/doc/SPEC.md). Typically,
multiple image storage services are used in order to provide greater uptime and
faster, more efficient resource utilization.
## DHE system management
The `dockerhubenterprise/manager` image is used to control the DHE system. This
image uses the Docker socket to orchestrate the multiple services that comprise
DHE.
$ sudo bash -c "$(sudo docker run dockerhubenterprise/manager [COMMAND])"
Supported commands are: `install`, `start`, `stop`, `restart`, `status`, and
`upgrade`.
> **Note**: `sudo` is needed for `dockerhubenterprise/manager` commands to
> ensure that the Bash script is run with full access to the Docker host.
## Next Steps
For information on installing DHE, take a look at the [Installation instructions](./install.md).

page_title: Docker Hub Enterprise: Configuration options
page_description: Configuration instructions for Docker Hub Enterprise
page_keywords: docker, documentation, about, technology, understanding, enterprise, hub, registry
# Configuration options
This page will help you properly configure Docker Hub Enterprise (DHE) so it can
run in your environment.
Start with DHE loaded in your browser and click the "Settings" tab to view
configuration options. You'll see options for configuring:
* Domains and ports
* Security settings
* Storage settings
* Authentication settings
* Your DHE license
## Domains and Ports
![Domain and Ports page</admin/settings#http>](../assets/admin-settings-http.png)
* *Domain Name*: **required**; defaults to an empty string, the fully qualified domain name assigned to the DHE host.
* *Load Balancer HTTP Port*: defaults to 80, used as the entry point for the image storage service. To see load balancer status, you can query
http://&lt;dhe-host&gt;/load_balancer_status.
* *Load Balancer HTTPS Port*: defaults to 443, used as the secure entry point
for the image storage service.
* *HTTP_PROXY*: defaults to an empty string, proxy server for HTTP requests.
* *HTTPS_PROXY*: defaults to an empty string, proxy server for HTTPS requests.
* *NO_PROXY*: defaults to an empty string, proxy bypass for HTTP and HTTPS requests.
> **Note**: If you need DHE to re-generate a self-signed certificate at some
> point, you'll need to first delete `/usr/local/etc/dhe/ssl/server.pem`, and
> then restart the DHE containers, either by changing and saving the "Domain Name",
> or using `bash -c "$(docker run dockerhubenterprise/manager restart)"`.
## Security
![Security settings page</admin/settings#security>](../assets/admin-settings-security.png)
* *SSL Certificate*: Used to enter the hash (string) from the SSL Certificate.
This cert must be accompanied by its private key, entered below.
* *Private Key*: The hash from the private key associated with the provided
SSL Certificate (as a standard x509 key pair).
In order to run, DHE requires encrypted communications via HTTPS/SSL between (a) the DHE registry and your Docker Engine(s), and (b) between your web browser and the DHE admin server. There are a few options for setting this up:
1. You can use the self-signed certificate DHE generates by default.
2. You can generate your own certificates using a public service or your enterprise's infrastructure. See the [Generating SSL certificates](#generating-ssl-certificates) section for the options available.
If you are generating your own certificates, you can install them by following the instructions for
[Adding your own registry certificates to DHE](#adding-your-own-registry-certificates-to-dhe).
On the other hand, if you choose to use the DHE-generated certificates, or the
certificates you generate yourself are not trusted by your client Docker hosts,
you will need to do one of the following:
* [Install a registry certificate on all of your client Docker daemons](#installing-registry-certificates-on-client-docker-daemons),
* Set your [client Docker daemons to run with an unconfirmed connection to the registry](#if-you-cant-install-the-certificates).
### Generating SSL certificates
There are three basic approaches to generating certificates:
1. Most enterprises will have private key infrastructure (PKI) in place to
generate keys. Consult with your security team or whomever manages your private
key infrastructure. If you have this resource available, Docker recommends you
use it.
2. If your enterprise can't provide keys, you can use a public Certificate
Authority (CA) like "InstantSSL.com" or "RapidSSL.com" to generate a
certificate. If your certificates are generated using a globally trusted
Certificate Authority, you won't need to install them on all of your
client Docker daemons.
3. Use the self-signed registry certificate generated by DHE, and install it
onto the client Docker daemon hosts as shown below.
### Adding your own Registry certificates to DHE
Whichever method you use to generate certificates, once you have them
you can set up your DHE server to use them by navigating to the "Settings" page,
going to "Security," and putting the SSL Certificate text (including all
intermediate Certificates, starting with the host) into the
"SSL Certificate" edit box, and the previously generated Private key into
the "SSL Private Key" edit box.
Click the "Save" button, and then wait for the DHE Admin site to restart and
reload. It should now be using the new certificate.
Once the "Security" page has reloaded, it will show `#` hashes instead of the
certificate text you pasted in.
If your certificate is signed by a chain of Certificate Authorities that are
already trusted by your Docker daemon servers, you can skip the "Installing
registry certificates" step below.
### Installing Registry certificates on client Docker daemons
If your certificates do not have a trusted Certificate Authority, you will need
to install them on each client Docker daemon host.
The procedure for installing the DHE certificates on each Linux distribution has
slightly different steps, as shown below.
You can test this certificate using `curl`:
```
$ curl https://dhe.yourdomain.com/v2/
curl: (60) SSL certificate problem: self signed certificate
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
$ curl --cacert /usr/local/etc/dhe/ssl/server.pem https://dhe.yourdomain.com/v2/
{"errors":[{"code":"UNAUTHORIZED","message":"access to the requested resource is not authorized","detail":null}]}
```
Continue by following the steps corresponding to your chosen OS.
#### Ubuntu/Debian
```
$ export DOMAIN_NAME=dhe.yourdomain.com
$ openssl s_client -connect $DOMAIN_NAME:443 -showcerts </dev/null 2>/dev/null | openssl x509 -outform PEM | tee /usr/local/share/ca-certificates/$DOMAIN_NAME.crt
$ update-ca-certificates
Updating certificates in /etc/ssl/certs... 1 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d....done.
$ service docker restart
docker stop/waiting
docker start/running, process 29291
```
#### RHEL
```
$ export DOMAIN_NAME=dhe.yourdomain.com
$ openssl s_client -connect $DOMAIN_NAME:443 -showcerts </dev/null 2>/dev/null | openssl x509 -outform PEM | tee /etc/pki/ca-trust/source/anchors/$DOMAIN_NAME.crt
$ update-ca-trust
$ /bin/systemctl restart docker.service
```
#### Boot2Docker 1.6.0
Install the CA cert (or the auto-generated cert) by adding the following to
your `/var/lib/boot2docker/bootsync.sh`:
```
#!/bin/sh
cat /var/lib/boot2docker/server.pem >> /etc/ssl/certs/ca-certificates.crt
```
Then get the certificate from the new DHE server using:
```
$ openssl s_client -connect dhe.yourdomain.com:443 -showcerts </dev/null 2>/dev/null | openssl x509 -outform PEM | sudo tee -a /var/lib/boot2docker/server.pem
```
If your certificate chain is complicated, you may want to use the changes in
[Pull request 807](https://github.com/boot2docker/boot2docker/pull/807/files)
Now you can either reboot your Boot2Docker virtual machine, or run the following to
install the server certificate, and then restart the Docker daemon.
```
$ sudo chmod 755 /var/lib/boot2docker/bootsync.sh
$ sudo /var/lib/boot2docker/bootsync.sh
$ sudo /etc/init.d/docker restart`.
```
### If you can't install the certificates
If for some reason you can't install the certificate chain on a client Docker host,
or your certificates do not have a global CA, you can configure your Docker daemon to run in "insecure" mode. This is done by adding an extra flag,
`--insecure-registry host-ip|domain-name`, to your client Docker daemon startup flags.
You'll need to restart the Docker daemon for the change to take effect.
This flag means that the communications between your Docker client and the DHE
Registry server are still encrypted, but the client Docker daemon is not
confirming that the Registry connection is not being hijacked or diverted.
> **Note**: If you enter a "Domain Name" into the "Security" settings, it needs
> to be DNS resolvable on any client Docker daemons that are running in
> "insecure-registry" mode.
To set the flag, follow the directions below for your operating system.
#### Ubuntu
On Ubuntu 14.04 LTS, you customize the Docker daemon configuration with the
`/etc/defaults/docker` file.
Open or create the `/etc/defaults/docker` file, and add the
`--insecure-registry` flag to the `DOCKER_OPTS` setting (which may need to be
added or uncommented) as follows:
```
DOCKER_OPTS="--insecure-registry dhe.yourdomain.com"
```
Then restart the Docker daemon with `sudo service docker restart`.
#### RHEL
On RHEL, you customize the Docker daemon configuration with the
`/etc/sysconfig/docker` file.
Open or create the `/etc/sysconfig/docker` file, and add the
`--insecure-registry` flag to the `OPTIONS` setting (which may need to be
added or uncommented) as follows:
```
OPTIONS="--insecure-registry dhe.yourdomain.com"
```
Then restart the Docker daemon with `sudo service docker restart`.
### Boot2Docker
On Boot2Docker, you customize the Docker daemon configuration with the
`/var/lib/boot2docker/profile` file.
Open or create the `/var/lib/boot2docker/profile` file, and add an `EXTRA_ARGS`
setting as follows:
```
EXTRA_ARGS="--insecure-registry dhe.yourdomain.com"
```
Then restart the Docker daemon with `sudo /etc/init.d/docker restart`.
## Image Storage Configuration
DHE offers multiple methods for image storage, which are defined using specific
storage drivers. Image storage can be local, remote, or on a cloud service such
as S3. Storage drivers can be added or customized via the DHE storage driver
API.
![Storage settings page</admin/settings#storage>](../assets/admin-settings-storage.png)
* *Yaml configuration file*: This file (`/usr/local/etc/dhe/storage.yml`) is
used to configure the image storage services. The editable text of the file is
displayed in the dialog box. The schema of this file is identical to that used
by the [Registry 2.0](http://docs.docker.com/registry/configuration/).
* If you are using the file system driver to provide local image storage, you will need to specify a root directory which will get mounted as a sub-path of
`/var/local/dhe/image-storage`. The default value of this root directory is
`/local`, so the full path to it is `/var/local/dhe/image-storage/local`.
> **Note:**
> Saving changes you've made to settings will restart the Docker Hub Enterprise
> instance. The restart may cause a brief interruption for users of the image
> storage system.
## Authentication
The current authentication methods are `None`, `Basic` and `LDAP`.
The `Basic` setting includes:
![Basic authentication settings page</admin/settings#auth>](../assets/admin-settings-authentication-basic.png)
* A button to add one user, or to upload a CSV file containing username,
password pairs
* A DHE website Administrator Filter, allowing you to either
* * 'Allow all authenticated users' to log into the DHE admin web interface, or
* * 'Whitelist usernames', which allows you to restrict access to the web
interface to the listed set of users.
The `LDAP` setting includes:
![LDAP authentication settings page</admin/settings#auth>](../assets/admin-settings-authentication-ldap.png)
* *Use StartTLS*: defaults to unchecked, check to enable StartTLS
* *LDAP Server URL*: **required**; defaults to null, LDAP server URL (e.g., - ldap://example.com)
* *User Base DN*: **required**; defaults to null, user base DN in the form
(e.g., - dc=example,dc=com)
* *User Login Attribute*: **required**; defaults to null, user login attribute
(e.g., - uid or sAMAccountName)
* *Search User DN*:** required**; defaults to null, search user DN
(e.g., - domain\username)
* *Search User Password*: **required**; defaults to null, search user password
* A *DHE Registry User filter*, allowing you to either
* * 'Allow all authenticated users' to push or pull any images, or
* * 'Filter LDAP search results', which allows you to restrict DHE registry pull
and push to users matching the LDAP filter,
* * 'Whitelist usernames', which allows you to restrict DHE registry pull and
push to the listed set of users.
* A *DHE website Administrator filter*, allowing you to either
* * 'Allow all authenticated users' to log into the DHE admin web interface, or
* * 'Filter LDAP search results', which allows you to restrict DHE admin web access to users matching the LDAP filter,
* * 'Whitelist usernames', which allows you to restrict access to the web interface to the listed set of users.

# Install
## Overview
This document describes the process of obtaining, installing, and securing
Docker Hub Enterprise (DHE). DHE is installed from Docker containers. Once
installed, you will need to select a method of securing it. This doc will
explain the options you have for security and help you find the resources needed
to configure it according to your chosen method. More configuration details can
be found in the [DHE Configuration page](./configuration.md).
Specifically, installation requires completion of these steps, in order:
1. Acquire a license by purchasing DHE or requesting a trial license.
2. Install the commercially supported Docker Engine.
3. Install DHE
4. Add your license to your DHE instance
## Licensing
In order to run DHE, you will need to acquire a license, either by purchasing
DHE or requesting a trial license. The license will be associated with your
Docker Hub account or Docker Hub organization (so if you don't have an account,
you'll need to set one up, which can be done at the same time as your license
request). To get your license or start your trial, please contact our
[sales department](mailto:sales@docker.com). Upon completion of your purchase or
request, you will receive an email with further instructions for licensing your
copy of DHE.
## Prerequisites
DHE requires the following:
* Commercially supported Docker Engine 1.6.0 or later running on an
Ubuntu 14.04 LTS, RHEL 7.1 or RHEL 7.0 host. (See below for instructions on how
to install the commercially supported Docker Engine.)
> **Note:** In order to remain in compliance with your DHE support agreement,
> you must use the current version of commercially supported Docker Engine.
> Running the regular, open source version of Engine is **not** supported.
* Your Docker daemon needs to be listening to the Unix socket (the default) so
that it can be bind-mounted into the DHE management containers, allowing
DHE to manage itself and its updates. For this reason, your DHE host will also
need internet connectivity so it can access the updates.
* Your host also needs to have TCP ports `80` and `443` available for the DHE
container port mapping.
* You will also need the Docker Hub user-name and password used when obtaining
the DHE license (or the user-name of an administrator of the Hub organization
that obtained an Enterprise license).
## Installing the Commercially Supported Docker Engine
Since DHE is installed using Docker, the commercially supported Docker Engine
must be installed first. This is done with an RPM or DEB repository, which you
set up using a Bash script downloaded from the [Docker Hub](https://hub.docker.com).
### Download the commercially supported Docker Engine installation script
To download the commercially supported Docker Engine Bash installation script,
log in to the [Docker Hub](https://hub.docker.com) with the user-name used to
obtain your license . Once you're logged in, go to the
["Enterprise Licenses"](https://registry.hub.docker.com/account/licenses/) page
in your Hub account's "Settings" section.
Select your intended host operating system from the "Download CS Engine" drop-
down at the top right of the page and then, once the Bash setup script is
downloaded, follow the steps below appropriate for your chosen OS.
![Docker Hub Docker engine install dropdown](../assets/docker-hub-org-enterprise-license-CSDE-dropdown.png)
### RHEL 7.0/7.1 installation
First, copy the downloaded Bash setup script to your RHEL host. Next, run the
following to install commercially supported Docker Engine and its dependencies,
and then start the Docker daemon:
```
$ sudo yum update && sudo yum upgrade
$ chmod 755 docker-cs-engine-rpm.sh
$ sudo ./docker-cs-engine-rpm.sh
$ sudo yum install docker-engine-cs
$ sudo systemctl enable docker.service
$ sudo systemctl start docker.service
```
In order to simplify using Docker, you can get non-sudo access to the Docker
socket by adding your user to the `docker` group, then logging out and back in
again:
```
$ sudo usermod -a -G docker $USER
$ exit
```
> **Note**: you may need to reboot your server to update its RHEL kernel.
### Ubuntu 14.04 LTS installation
First, copy the downloaded Bash setup script to your Ubuntu host. Next, run the
following to install commercially supported Docker Engine and its dependencies:
```
$ sudo apt-get update && sudo apt-get upgrade
$ chmod 755 docker-cs-engine-deb.sh
$ sudo ./docker-cs-engine-deb.sh
$ sudo apt-get install docker-engine-cs
```
In order to simplify using Docker, you can get non-sudo access to the Docker
socket by adding your user to the `docker` group, then logging out and back in
again:
```
$ sudo usermod -a -G docker $USER
$ exit
```
> **Note**: you may need to reboot your server to update its LTS kernel.
## Installing Docker Hub Enterprise
Once the commercially supported Docker Engine is installed, you can install DHE
itself. DHE is a self-installing application built and distributed using Docker
and the [Docker Hub](https://registry.hub.docker.com/). It is able to restart
and reconfigure itself using the Docker socket that is bind-mounted to its
container.
Start installing DHE by running the "dockerhubenterprise/manager" container:
```
$ sudo bash -c "$(sudo docker run dockerhubenterprise/manager install)"
```
> **Note**: `sudo` is needed for `dockerhubenterprise/manager` commands to
> ensure that the Bash script is run with full access to the Docker host.
You can also find this command on the "Enterprise Licenses" section of your Hub
user profile. The command will execute a shell script that creates the needed
directories and then runs Docker to pull DHE's images and run its containers.
Depending on your internet connection, this process may take several minutes to
complete.
A successful installation will pull a large number of Docker images and should
display output similar to:
```
$ sudo bash -c "$(sudo docker run dockerhubenterprise/manager install)"

```
Once this process completes, you should be able to manage and configure your DHE
instance by pointing your browser to `https://<host-ip>/`.
Your browser will warn you that this is an unsafe site, with a self-signed,
untrusted certificate. This is normal and expected; allow this connection
temporarily.
### Setting the DHE Domain Name
The DHE Administrator site will also warn that the "Domain Name" is not set. Go
to the "Settings" tab, and set the "Domain Name" to the full host-name of your
DHE server.
Hitting the "Save and Restart DHE Server" button will generate a new certificate, which will be used
by both the DHE Administrator web interface and the DHE Registry server.
After the server restarts, you will again need to allow the connection to the untrusted DHE web admin site.
![http settings page</admin/settings#http>](../assets/admin-settings-http-unlicensed.png)
Lastly, you will see a warning notifying you that this instance of DHE is
unlicensed. You'll correct this in the next step.
### Add your license
The DHE registry services will not start until you add your license.
To do that, you'll first download your license from the Docker Hub and then
upload it to your DHE web admin server. Follow these steps:
1. If needed, log back into the [Docker Hub](https://hub.docker.com)
using the user-name you used when obtaining your license. Go to "Settings" (in
the menu under your user-name, top right) to get to your account settings, and
then click on "Enterprise Licenses" in the side bar at left.
2. You'll see a list of available licenses. Click on the download button to
obtain the license file you'd like to use.
![Download DHE license](../assets/docker-hub-org-enterprise-license.png)
3. Next, go to your DHE instance in your browser and click on the Settings tab
and then the "License" tab. Click on the "Upload license file" button, which
will open a standard file browser. Locate and select the license file you
downloaded in step 2, above. Approve the selection to close the dialog.
![http settings page</admin/settings#license>](../assets/admin-settings-license.png)
4. Click the "Save and Restart DHE" button, which will quit DHE and then restart it, registering
the new license.
5. Verify the acceptance of the license by confirming that the "unlicensed copy"
warning is no longer present.
### Securing DHE
Securing DHE is **required**. You will not be able to push or pull from DHE until you secure it.
There are several options and methods for securing DHE. For more information,
see the [configuration documentation](./configuration.md#security)
### Using DHE to push and pull images
Now that you have DHE configured with a "Domain Name" and have your client
Docker daemons configured with the required security settings, you can test your
setup by following the instructions for
[Using DHE to Push and pull images](./userguide.md#using-dhe-to-push-and-pull-images).
### DHE web interface and registry authentication
By default, there is no authentication set on either the DHE web admin
interface or the DHE registry. You can restrict access using an in-DHE
configured set of users (and passwords), or you can configure DHE to use LDAP-
based authentication.
See [DHE Authentication settings](./configuration.md#authentication) for more
details.
# Upgrading
DHE has been designed to allow on-the-fly software upgrades. Start by
clicking on the "System Health" tab. In the upper, right-hand side of the
dashboard, below the navigation bar, you'll see the currently installed version
(e.g., `Current Version: 0.1.12345`).
If your DHE instance is the latest available, you will also see the message:
"System Up to Date."
If there is an upgrade available, you will see the message "System Update
Available!" alongside a button labeled "Update to Version X.XX". To upgrade, DHE
will pull new DHE container images from the Docker Hub. If you have not already
connected to Docker Hub, DHE will prompt you to log in.
The upgrade process requires a small amount of downtime to complete. To complete
the upgrade, DHE will:
* Connect to the Docker Hub to pull new container images with the new version of
DHE.
* Deploy those containers
* Shut down the old containers
* Resolve any necessary links/urls.
Assuming you have a decent internet connection, the entire upgrade process
should complete within a few minutes.
## Next Steps
For information on configuring DHE for your environment, take a look at the
[Configuration instructions](./configuration.md).

# Docker Hub Enterprise Quick Start: Basic User Workflow
## Overview
This Quick Start Guide will give you a hands-on look at the basics of using
Docker Hub Enterprise (DHE), Dockers on-premise image storage application.
This guide will walk you through using DHE to complete a typical, and critical,
part of building a development pipeline: setting up a Jenkins instance. Once you
complete the task, you should have a good idea of how DHE works and how it might
be useful to you.
Specifically, this guide demonstrates the process of retrieving the
[official Docker image for Jenkins](https://registry.hub.docker.com/_/jenkins/),
customizing it to suit your needs, and then hosting it on your private instance
of DHE located inside your enterprises firewalled environment. Your developers
will then be able to retrieve the custom Jenkins image in order to use it to
build CI/CD infrastructure for their projects, no matter the platform theyre
working from, be it a laptop, a VM, or a cloud provider.
The guide will walk you through the following steps:
1. Pulling the official Jenkins image from the public Docker Hub
2. Customizing the Jenkins image to suit your needs
3. Pushing the customized image to DHE
4. Pulling the customized image from DHE
4. Launching a container from the custom image
5. Using the new Jenkins container
You should be able to complete this guide in about thirty minutes.
> **Note:** This guide assumes you have installed a working instance of DHE
> reachable at dhe.yourdomain.com. If you need help installing and configuring
> DHE, please consult the
[installation instructions](./install.md).
## Pulling the official Jenkins image
> **Note:** This guide assumes you are familiar with basic Docker concepts such
> as images, containers, and registries. If you need to learn more about Docker
> fundamentals, please consult the
> [Docker user guide](http://docs.docker.com/userguide/).
First, you will retrieve a copy of the official Jenkins image from the Docker Hub. From the CLI of a machine running the Docker Engine on your network, use
the
[`docker pull`](https://docs.docker.com/reference/commandline/cli/#pull)
command to pull the public Jenkins image.
$ docker pull jenkins
> **Note:** This guide assumes you can run Docker commands from a machine where
> you are a member of the `docker` group, or have root privileges. Otherwise, you may
> need to add `sudo` to the example commands below.
Docker will start the process of pulling the image from the Hub. Once it has completed, the Jenkins image should be visible in the output of a [`docker images`](https://docs.docker.com/reference/commandline/cli/#images) command:
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
jenkins latest 1a7cc22b0ee9 6 days ago 662 MB
> **Note:** Because the `pull` command did not specify any tags, it will pull
> the latest version of the public Jenkins image. If your enterprise environment
> requires you to use a specific version, add the tag for the version you need
> (e.g., `jenkins:1.565`).
## Customizing the Jenkins image
Now that you have a local copy of the Jenkins image, youll customize it so that
the containers it builds will integrate with your infrastructure. To do this,
youll create a custom Docker image that adds a Jenkins plugin that provides
fine grained user management. Youll also configure Jenkins to be more secure by
disabling HTTP access and forcing it to use HTTPS.
Youll do this by using a `Dockerfile` and the `docker build` command.
> **Note:** These are obviously just a couple of examples of the many ways you
> can modify and configure Jenkins. Feel free to add or substitute whatever
> customization is necessary to run Jenkins in your environment.
### Creating a `build` context
In order to add the new plugin and configure HTTPS access to the custom Jenkins
image, you need to:
1. Create text file that defines the new plugin
2. Create copies of the private key and certificate
All of the above files need to be in the same directory as the Dockerfile you
will create in the next step.
1. Create a build directory called `build`, and change to that new directory:
$ mkdir build && cd build
In this directory, create a new file called `plugins` and add the following
line:
role-strategy:2.2.0
(The plugin version used above was the latest version at the time of writing.)
2. You will also need to make copies of the servers private key and certificate. Give the copies the following names — `https.key` and `https.pem`.
> **Note:** Because creating new keys varies widely by platform and
> implementation, this guide wont cover key generation. We assume you have
> access to existing keys. If you dont have access, or cant generate keys
> yourself, feel free to skip the steps involving them and HTTPS config. The
> guide will still walk you through building a custom Jenkins image and pushing
> and pulling that image using DHE.
### Creating a Dockerfile
In the same directory as the `plugins` file and the private key and certificate,
create a new [`Dockerfile`](https://docs.docker.com/reference/builder/) with the
following contents:
FROM jenkins
#New plugins must be placed in the plugins file
COPY plugins /usr/share/jenkins/plugins
#The plugins.sh script will install new plugins
RUN /usr/local/bin/plugins.sh /usr/share/jenkins/plugins
#Copy private key and cert to image
COPY https.pem /var/lib/jenkins/cert
COPY https.key /var/lib/jenkins/pk
#Configure HTTP off and HTTPS on, using port 1973
ENV JENKINS_OPTS --httpPort=-1 --httpsPort=1973 --httpsCertificate=/var/lib/jenkins/cert --httpsPrivateKey=/var/lib/jenkins/pk
The first `COPY` instruction in the above will copy the `plugin` file created
earlier into the `/usr/share/jenkins` directory within the custom image you are
defining with the `Dockerfile`.
The `RUN` instruction will execute the `/usr/local/bin/plugins.sh` script with
the newly copied `plugins` file, which will install the listed plugin.
The next two `COPY` instructions copy the servers private key and certificate
into the required directories within the new image.
The `ENV` instruction creates an environment variable called `JENKINS_OPT` in
the image you are about to create. This environment variable will be present in
any containers launched form the image and contains the required settings to
tell Jenkins to disable HTTP and operate over HTTPS.
> **Note:** You can specify any valid port number as part of the `JENKINS_OPT`
> environment variable declared above. The value `1973` used in the example is
> arbitrary.
The `Dockerfile`, the `plugins` file, as well as the private key and
certificate, must all be in the same directory because the `docker build`
command uses the directory that contains the `Dockerfile` as its “build
context”. Only files contained within that “build context” will be included in
the image being built.
### Building your custom image
Now that the `Dockerfile`, the `plugins` file, and the files required for HTTPS
operation are created in your current working directory, you can build your
custom image using the
[`docker build` command](https://docs.docker.com/reference/commandline/cli/#build):
docker build -t dhe.yourdomain.com/ci-infrastructure/jnkns-img .
> **Note:** Dont miss the period (`.`) at the end of the command above. This
> tells the `docker build` command to use the current working directory as the
> "build context".
This command will build a new Docker image called `jnkns-img` which is based on
the public Jenkins image you pulled earlier, but contains all of your
customization.
Please note the use of the `-t` flag in the `docker build` command above. The
`-t` flag lets you tag an image so it can be pushed to a custom repository. In
the example above, the new image is tagged so it can be pushed to the
`ci-infrastructure` Repository within the `dhe.yourdomain.com` registry (your
local DHE instance). This will be important when you need to `push` the
customized image to DHE later.
A `docker images` command will now show the custom image alongside the Jenkins
image pulled earlier:
$ sudo docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
dhe.yourdomain.com/ci-infrastructure/jnkns-img latest fc0ab3008d40 2 minutes ago 674.5 MB
jenkins latest 1a7cc22b0ee9 6 days ago 662 MB
## Pushing to Docker Hub Enterprise
Now that youve create the custom image, it can be pushed to DHE using the
[`docker push`command](https://docs.docker.com/reference/commandline/cli/#push):
$ docker push dhe.yourdomain.com/ci-infrastructure/jnkns-img
511136ea3c5a: Image successfully pushed
848d84b4b2ab: Image successfully pushed
71d9d77ae89e: Image already exists
<truncated ouput...>
492ed3875e3e: Image successfully pushed
fc0ab3008d40: Image successfully pushed
You can view the traffic throughput while the custom image is being pushed from
the `System Health` tab in DHE:
![DHE console push throughput](../assets/console-push.png)
Once the image is successfully pushed, it can be downloaded, or pulled, by any
Docker host that has access to DHE.
## Pulling from Docker Hub Enterprise
To pull the `jnkns-img` image from DHE, run the
[`docker pull`](https://docs.docker.com/reference/commandline/cli/#pull)
command from any Docker Host that has access to your DHE instance:
$ docker pull dhe.yourdomain.com/ci-infrastructure/jnkns-img
latest: Pulling from dhe.yourdomain.com/ci-infrastructure/jnkns-img
511136ea3c5a: Pull complete
848d84b4b2ab: Pull complete
71d9d77ae89e: Pull complete
<truncated ouput...>
492ed3875e3e: Pull complete
fc0ab3008d40: Pull complete
dhe.yourdomain.com/ci-infrastructure/jnkns-img:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.
Status: Downloaded newer image for dhe.yourdomain.com/ci-infrastructure/jnkns-img:latest
You can view the traffic throughput while the custom image is being pulled from
the `System Health` tab in DHE:
![DHE console pull throughput](../assets/console-pull.png)
Now that the `jnkns-img` image has been pulled locally from DHE, you can view it
in the output of the `docker images` command:
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
dhe.yourdomain.com/ci-infrastructure/jnkns-img latest fc0ab3008d40 8 minutes ago 674.5 MB
## Launching a custom Jenkins container
Now that youve successfully pulled the customized Jenkins image from DHE, you
can create a container from it with the
[`docker run` command](https://docs.docker.com/reference/commandline/cli/#run):
$ docker run -p 1973:1973 --name jenkins01 dhe.yourdomain.com/ci-infrastructure/jnkns-img
/usr/share/jenkins/ref/init.groovy.d/tcp-slave-angent-port.groovy
/usr/share/jenkins/ref/init.groovy.d/tcp-slave-angent-port.groovy -> init.groovy.d/tcp-slave-angent-port.groovy
copy init.groovy.d/tcp-slave-angent-port.groovy to JENKINS_HOME
/usr/share/jenkins/ref/plugins/role-strategy.hpi
/usr/share/jenkins/ref/plugins/role-strategy.hpi -> plugins/role-strategy.hpi
copy plugins/role-strategy.hpi to JENKINS_HOME
/usr/share/jenkins/ref/plugins/dockerhub.hpi
/usr/share/jenkins/ref/plugins/dockerhub.hpi -> plugins/dockerhub.hpi
copy plugins/dockerhub.hpi to JENKINS_HOME
<truncated output...>
INFO: Jenkins is fully up and running
> **Note:** The `docker run` command above maps port 1973 in the container
> through to port 1973 on the host. This is the HTTPS port you specified in the
> Dockerfile earlier. If you specified a different HTTPS port in your
> Dockerfile, you will need to substitute this with the correct port numbers for
> your environment.
You can view the newly launched a container, called `jenkins01`, using the
[`docker ps` command](https://docs.docker.com/reference/commandline/cli/#ps):
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS ...PORTS NAMES
2e5d2f068504 dhe.yourdomain.com/ci-infrastructure/jnkns-img:latest "/usr/local/bin/jenk About a minute ago Up About a minute 50000/tcp, 0.0.0.0:1973->1973/tcp jenkins01
## Accessing the new Jenkins container
The previous `docker run` command mapped port `1973` on the container to port
`1973` on the Docker host, so the Jenkins Web UI can be accessed at
`https://<docker-host>:1973` (Dont forget the `s` at the end of `https`.)
> **Note:** If you are using a self-signed certificate, you may get a security
> warning from your browser telling you that the certificate is self-signed and
> not trusted. You may wish to add the certificate to the trusted store in order
> to prevent further warnings in the future.
![Jenkins landing page](../assets/jenkins-ui.png)
From within the Jenkins Web UI, navigate to `Manage Jenkins` (on the left-hand
pane) > `Manage Plugins` > `Installed`. The `Role-based Authorization Strategy`
plugin should be present with the `Uninstall` button available to the right.
![Jenkins plugin manager](../assets/jenkins-plugins.png)
In another browser session, try to access Jenkins via the default HTTP port 8080
`http://<docker-host>:8080`. This should result in a “connection timeout,”
showing that Jenkins is not available on its default port 8080 over HTTP.
This demonstration shows your Jenkins image has been configured correctly for
HTTPS access, your new plugin was added and is ready for use, and HTTP access
has been disabled. At this point, any member of your team can use `docker pull`
to access the image from your DHE instance, allowing them to access a
configured, secured Jenkins instance that can run on any infrastructure.

# Docker Hub Enterprise User's Guide
This guide covers tasks and functions a user of Docker Hub Enterprise (DHE) will
need to know about, such as pushing or pulling images, etc. For tasks DHE
administrators need to accomplish, such as configuring or monitoring DHE, please
visit the [Administrator's Guide](./adminguide.md).
## Using DHE to push and pull images
The primary use case for DHE users is to push and pull images to and from the
DHE image storage service. The following instructions describe these procedures.
> **Note**: If your DHE instance has authentication enabled, you will need to
>use your command line to `docker login <dhe-hostname>` (e.g., `docker login
> dhe.yourdomain.com`).
>
> Failures due to unauthenticated `docker push` and `docker pull` commands will
> look like :
>
> $ docker pull dhe.yourdomain.com/hello-world
> Pulling repository dhe.yourdomain.com/hello-world
> FATA[0001] Error: image hello-world:latest not found
>
> $ docker push dhe.yourdomain.com/hello-world
> The push refers to a repository [dhe.yourdomain.com/hello-world] (len: 1)
> e45a5af57b00: Image push failed
> FATA[0001] Error pushing to registry: token auth attempt for registry https://dhe.yourdomain.com/v2/: https://> dhe.yourdomain.com/auth/v2/token/?scope=repository%3Ahello-world%3Apull%2Cpush&service=dhe.yourdomain.com > request failed with status: 401 Unauthorized
1. Pull the `hello-world` official image from the Docker Hub. By default, if
Docker can't find an image locally, it will attempt to pull the image from the
Docker Hub.
`$ docker pull hello-world`
2. List your available images.
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
hello-world latest e45a5af57b00 3 months ago 910 B
Your list should include the `hello-world` image from the earlier run.
3. Re-tag the `hello-world` image so that it refers to your DHE server.
`$ docker tag hello-world:latest dhe.yourdomain.com/demouser/hello-mine:latest`
The command labels a `hello-world:latest` image using a new tag in the
`[REGISTRYHOST/][USERNAME/]NAME[:TAG]` format. The `REGISTRYHOST` in this
case is the DHE server, `dhe.yourdomain.com`, and the `USERNAME` is
`demouser`.
4. List your new image.
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
hello-world latest e45a5af57b00 3 months ago 910 B
dhe.yourdomain.com/demouser/hello-mine latest e45a5af57b00 3 months ago 910 B
You should see your new image label in the listing, with the same `IMAGE ID`
as the Official image.
5. Push this new image to your DHE server.
`$ docker push dhe.yourdomain.com/demouser/hello-mine:latest`
6. Set up a test of DHE by removing all images from your local environment:
`$ docker rmi -f $(docker images -q -a)`
This command is for illustrative purposes only: removing the image forces
any subsequent `run` to pull from a remote registry (such as DHE) rather
than from a local cache. If you run `docker images` after this you should
not see any instance of `hello-world` or `hello-mine` in your images list.
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
7. Try running `hello-mine`.
$ docker run hello-mine
Unable to find image 'hello-mine:latest' locally
Pulling repository hello-mine
FATA[0007] Error: image library/hello-mine:latest not found
The `run` command fails because your new image doesn't exist on the Docker Hub.
8. Run `hello-mine` again, this time pointing it to pull from DHE:
$ docker run dhe.yourdomain.com/demouser/hello-mine
latest: Pulling from dhe.yourdomain.com/demouser/hello-mine
511136ea3c5a: Pull complete

If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry dhe.yourdomain.com` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/dhe.yourdomain.com/ca.crt
9. You have now successfully created a custom image, `hello-mine`, tagged it,
and pushed it to the image storage provided by your DHE instance. You then
pulled that image back down from DHE and onto your machine, where you can
use it to create a container containing the "Hello World" application..
## Next Steps
For information on administering DHE, take a look at the [Administrator's Guide](./adminguide.md).
<!--TODO:
* mention that image aliases that are not in the same repository are not updated - either on push or pull
* but that multiple tags in one repo are pushed if you don't specify the `:tag` (ie, `imagename` does not always mean `imagename:latest`)
* show what happens for non-latest, and when there are more than one tag in a repo
* explain the fully-qualified repo/image name -->
