Install Docker on Manjaro i3


You can search for the package using pamac.

$ pamac search docker

The below will install docker along with two other packages, containerd and runc.

$ pamac install docker

Once installed, start and enable the service to start on boot.

$ sudo systemctl enable --now docker.service

You can test everything is okay and get back some basic information about your environment with the below commands.

$ sudo docker version
$ sudo docker info

Add your user to the docker group so you can run docker without first becoming root.

[andy@home-pc ~]$ sudo usermod -aG docker $USER

You will need to logout/login from your DE – or reboot – for the changes to take effect. After the reboot, you should be able to run docker command as your normal user. Go ahead and try to run the docker hello world example.

$ docker run hello-world

The output should indicate everything is working correctly. You may also want to install docker-compose too.

$ pamac install docker-compose

You can list all containers using the ps command.

[andy@home-pc ~]$ docker ps -a
CONTAINER ID   IMAGE                               COMMAND                  CREATED         STATUS                        PORTS     NAMES
dc8bb75d7529   hello-world                         "/hello"                 7 seconds ago   Exited (0) 6 seconds ago                clever_albattani

To remove the image, use rm on the container ID listed above. If you run the below rmi command, the output will also show you the referenced container ID.

[andy@home-pc ~]$ docker rmi hello-world
Error response from daemon: conflict: unable to remove repository reference "hello-world" (must force) - container dc8bb75d7529 is using its referenced image feb5d9fea6a5

To remove, use the rm command.

$ docker rm dc8bb75d7529

Now re-run the rmi command.

[andy@home-pc ~]$ docker rmi hello-world
