    11  # Gentoo
    12  
    13  Installing Docker on Gentoo Linux can be accomplished using one of two ways: the **official** way and the `docker-overlay` way.
    14  
    15  Official project page of [Gentoo Docker](https://wiki.gentoo.org/wiki/Project:Docker) team.
    16  
    17  ## Official way
    18  The first and recommended way if you are looking for a stable  
    19  experience is to use the official `app-emulation/docker` package directly  
    20  from the tree.
    21  
    22  If any issues arise from this ebuild including, missing kernel 
    23  configuration flags or dependencies, open a bug 
    24  on the Gentoo [Bugzilla](https://bugs.gentoo.org) assigned to `docker AT gentoo DOT org` 
    25  or join and ask in the official
    26  [IRC](http://webchat.freenode.net?channels=%23gentoo-containers&uio=d4) channel on the Freenode network.
    27  
    28  ## docker-overlay way
    29  
    30  If you're looking for a `-bin` ebuild, a live ebuild, or a bleeding edge
    31  ebuild, use the provided overlay, [docker-overlay](https://github.com/tianon/docker-overlay)
    32  which can be added using `app-portage/layman`. The most accurate and
    33  up-to-date documentation for properly installing and using the overlay
    34  can be found in the [overlay](https://github.com/tianon/docker-overlay/blob/master/README.md#using-this-overlay).
    35  
    36  If any issues arise from this ebuild or the resulting binary, including
    37  and especially missing kernel configuration flags or dependencies, 
    38  open an [issue](https://github.com/tianon/docker-overlay/issues) on 
    39  the `docker-overlay` repository or ping `tianon` directly in the `#docker` 
    40  IRC channel on the Freenode network.
    41  
    42  ## Installation
    43  
    44  ### Available USE flags
    45  
    46  | USE Flag      | Default | Description |
    47  | ------------- |:-------:|:------------|
    48  | aufs          |         |Enables dependencies for the "aufs" graph driver, including necessary kernel flags.|
    49  | btrfs         |         |Enables dependencies for the "btrfs" graph driver, including necessary kernel flags.|
    50  | contrib       |  Yes    |Install additional contributed scripts and components.|
    51  | device-mapper |  Yes    |Enables dependencies for the "devicemapper" graph driver, including necessary kernel flags.|
    52  | doc           |         |Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally.|
    53  | lxc           |         |Enables dependencies for the "lxc" execution driver.|
    54  | vim-syntax    |         |Pulls in related vim syntax scripts.|
    55  | zsh-completion|         |Enable zsh completion support.|
    56  
    57  USE flags are described in detail on [tianon's
    58  blog](https://tianon.github.io/post/2014/05/17/docker-on-gentoo.html).
    59  
    60  The package should properly pull in all the necessary dependencies and
    61  prompt for all necessary kernel options.
    62  
    63      $ sudo emerge -av app-emulation/docker
    64  
    65  >Note: Sometimes there is a disparity between the latest versions 
    66  >in the official **Gentoo tree** and the **docker-overlay**.  
    67  >Please be patient, and the latest version should propagate shortly.
    68  
    69  ## Starting Docker
    70  
    71  Ensure that you are running a kernel that includes all the necessary
    72  modules and configuration (and optionally for device-mapper
    73  and AUFS or Btrfs, depending on the storage driver you've decided to use).
    74  
    75  To use Docker, the `docker` daemon must be running as **root**.  
    76  To use Docker as a **non-root** user, add yourself to the **docker** 
    77  group by running the following command:
    78  
    79      $ sudo usermod -a -G docker user
    80   
    81  ### OpenRC
    82  
    83  To start the `docker` daemon:
    84  
    85      $ sudo /etc/init.d/docker start
    86  
    87  To start on system boot:
    88  
    89      $ sudo rc-update add docker default
    90  
    91  ### systemd
    92  
    93  To start the `docker` daemon:
    94  
    95      $ sudo systemctl start docker
    96  
    97  To start on system boot:
    98  
    99      $ sudo systemctl enable docker
   100     
   101  If you need to add an HTTP Proxy, set a different directory or partition for the
   102  Docker runtime files, or make other customizations, read our systemd article to
   103  learn how to [customize your systemd Docker daemon options](/articles/systemd/).
   104  
   105  ## Uninstallation
   106  
   107  To uninstall the Docker package:
   108  
   109      $ sudo emerge -cav app-emulation/docker
   110  
   111  To uninstall the Docker package and dependencies that are no longer needed:
   112  
   113      $ sudo emerge -C app-emulation/docker
   114  
   115  The above commands will not remove images, containers, volumes, or user created
   116  configuration files on your host. If you wish to delete all images, containers,
   117  and volumes run the following command:
   118  
   119      $ rm -rf /var/lib/docker
   120  
   121  You must delete the user created configuration files manually.
