**This instruction set is meant for hackers who want to try out Docker
|
|
on a variety of environments.**
|
|
|
|
Before following these directions, you should really check if a packaged
|
|
version of Docker is already available for your distribution. We have
|
|
packages for many distributions, and more keep showing up all the time!
|
|
|
|
## Check runtime dependencies
|
|
|
|
To run properly, docker needs the following software to be installed at
|
|
runtime:
|
|
|
|
- iptables version 1.4 or later
|
|
- Git version 1.7 or later
|
|
- procps (or similar provider of a "ps" executable)
|
|
- XZ Utils 4.9 or later
|
|
- a [properly mounted](
|
|
https://github.com/tianon/cgroupfs-mount/blob/master/cgroupfs-mount)
|
|
cgroupfs hierarchy (having a single, all-encompassing "cgroup" mount
|
|
point [is](https://github.com/dotcloud/docker/issues/2683)
|
|
[not](https://github.com/dotcloud/docker/issues/3485)
|
|
[sufficient](https://github.com/dotcloud/docker/issues/4568))
|
|
|
|
## Check kernel dependencies
|
|
|
|
Docker in daemon mode has specific kernel requirements. For details,
|
|
check your distribution in [*Installation*](../#installation-list).
|
|
|
|
In general, a 3.8 Linux kernel (or higher) is preferred, as some of the
|
|
prior versions have known issues that are triggered by Docker.
|
|
|
|
Note that Docker also has a client mode, which can run on virtually any
|
|
Linux kernel (it even builds on OSX!).
|
|
|
|
## Get the docker binary:
|
|
|
|
wget https://get.docker.io/builds/Linux/x86_64/docker-latest -O docker
|
|
chmod +x docker
|
|
|
|
> **Note**:
|
|
> If you have trouble downloading the binary, you can also get the smaller
|
|
> compressed release file:
|
|
> [https://get.docker.io/builds/Linux/x86_64/docker-latest.tgz](
|
|
> https://get.docker.io/builds/Linux/x86_64/docker-latest.tgz)
|
|
|
|
## Run the docker daemon
|
|
|
|
# start the docker in daemon mode from the directory you unpacked
|
|
sudo ./docker -d &
|
|
|
|
## Giving non-root access
|
|
|
|
The `docker` daemon always runs as the root user,
|
|
and since Docker version 0.5.2, the `docker` daemon
|
|
binds to a Unix socket instead of a TCP port. By default that Unix
|
|
socket is owned by the user *root*, and so, by default, you can access
|
|
it with `sudo`.
|
|
|
|
Starting in version 0.5.3, if you (or your Docker installer) create a
|
|
Unix group called *docker* and add users to it, then the
|
|
`docker` daemon will make the ownership of the Unix
|
|
socket read/writable by the *docker* group when the daemon starts. The
|
|
`docker` daemon must always run as the root user,
|
|
but if you run the `docker` client as a user in the
|
|
*docker* group then you don't need to add `sudo` to
|
|
all the client commands.
|
|
|
|
> **Warning**:
|
|
> The *docker* group (or the group specified with `-G`) is root-equivalent;
|
|
> see [*Docker Daemon Attack Surface*](
|
|
> ../../articles/security/#dockersecurity-daemon) details.
|
|
|
|
## Upgrades
|
|
|
|
To upgrade your manual installation of Docker, first kill the docker
|
|
daemon:
|
|
|
|
killall docker
|
|
|
|
Then follow the regular installation steps.
|
|
|
|
## Run your first container!
|
|
|
|
# check your docker version
|
|
sudo ./docker version
|
|
|
|
# run a container and open an interactive shell in the container
|
|
sudo ./docker run -i -t ubuntu /bin/bash
|
|
|
|
Continue with the [*Hello World*](../../examples/hello_world/#hello-world) example.
