Gentoo
Installing Docker on Gentoo Linux can be accomplished using one of two ways: the official way and the docker-overlay way.
Official project page of Gentoo Docker team.
Official way
The first and recommended way if you are looking for a stable
experience is to use the official app-emulation/docker package directly
from the tree.
If any issues arise from this ebuild including, missing kernel
configuration flags or dependencies, open a bug
on the Gentoo Bugzilla assigned to docker AT gentoo DOT org
or join and ask in the official
IRC channel on the Freenode network.
docker-overlay way
If you're looking for a -bin ebuild, a live ebuild, or a bleeding edge
ebuild, use the provided overlay, docker-overlay
which can be added using app-portage/layman. The most accurate and
up-to-date documentation for properly installing and using the overlay
can be found in the overlay.
If any issues arise from this ebuild or the resulting binary, including
and especially missing kernel configuration flags or dependencies,
open an issue on
the docker-overlay repository or ping tianon directly in the #docker
IRC channel on the Freenode network.
Installation
Available USE flags
| USE Flag | Default | Description |
|---|---|---|
| aufs | Enables dependencies for the "aufs" graph driver, including necessary kernel flags. | |
| btrfs | Enables dependencies for the "btrfs" graph driver, including necessary kernel flags. | |
| contrib | Yes | Install additional contributed scripts and components. |
| device-mapper | Yes | Enables dependencies for the "devicemapper" graph driver, including necessary kernel flags. |
| doc | Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally. | |
| lxc | Enables dependencies for the "lxc" execution driver. | |
| vim-syntax | Pulls in related vim syntax scripts. | |
| zsh-completion | Enable zsh completion support. |
USE flags are described in detail on tianon's blog.
The package should properly pull in all the necessary dependencies and prompt for all necessary kernel options.
$ sudo emerge -av app-emulation/docker
Note: Sometimes there is a disparity between the latest versions in the official Gentoo tree and the docker-overlay.
Please be patient, and the latest version should propagate shortly.
Starting Docker
Ensure that you are running a kernel that includes all the necessary modules and configuration (and optionally for device-mapper and AUFS or Btrfs, depending on the storage driver you've decided to use).
To use Docker, the docker daemon must be running as root.
To use Docker as a non-root user, add yourself to the docker
group by running the following command:
$ sudo usermod -a -G docker user
OpenRC
To start the docker daemon:
$ sudo /etc/init.d/docker start
To start on system boot:
$ sudo rc-update add docker default
systemd
To start the docker daemon:
$ sudo systemctl start docker
To start on system boot:
$ sudo systemctl enable docker
