Install Docker on Arch LinuxEstimated reading time: 2 minutes
Installing on Arch Linux can be handled via the package in community:
or the following AUR package:
The docker package will install the latest tagged version of docker. The docker-git package will build from the current master branch.
Docker depends on several packages which are specified as dependencies in the packages. The core dependencies are:
For the normal package a simple
$ sudo pacman -S docker
is all that is needed.
For the AUR package execute:
$ yaourt -S docker-git
The instructions here assume yaourt is installed. See Arch User Repository for information on building and installing packages from the AUR if you have not done so before.
There is a systemd service unit created for docker. To start the docker service:
$ sudo systemctl start docker
To start on system boot:
$ sudo systemctl enable docker
Custom daemon options
If you need to add an HTTP Proxy, set a different directory or partition for the Docker runtime files, or make other customizations, read our systemd article to learn how to customize your systemd Docker daemon options.
Running Docker with a manually-defined network
If you manually configure your network using
systemd-network version 220 or
higher, containers you start with Docker may be unable to access your network.
Beginning with version 220, the forwarding setting for a given network
net.ipv4.conf.<interface>.forwarding) defaults to off. This setting
prevents IP forwarding. It also conflicts with Docker which enables the
net.ipv4.conf.all.forwarding setting within a container.
To work around this, edit the
<interface>.network file in
/etc/systemd/network/ on your Docker host add the following block:
[Network] ... IPForward=kernel ...
This configuration allows IP forwarding from the container as expected.
To uninstall the Docker package:
$ sudo pacman -R docker
To uninstall the Docker package and dependencies that are no longer needed:
$ sudo pacman -Rns docker
The above commands will not remove images, containers, volumes, or user created configuration files on your host. If you wish to delete all images, containers, and volumes run the following command:
$ rm -rf /var/lib/docker
You must delete the user created configuration files manually.
