Steps

1. Install the Docker (docker) package using yay.

2. Add our user to the docker group:

   newgrp docker
   sudo usermod -aG docker ${USER}

3. Start and Enable the docker.service service.

Troubleshooting

IP Range Conflict

1. Should an IP range conflict occur, check IP range used by the docker daemon:

   ip route | grep docker

2. Fix by creating an /etc/docker/daemon.json file and change the base IP to a non-conflicting IP (i.e. 172.18.0.0/16):

   {
       "debug" : true,
       "default-address-pools" : [
           {
               "base" : "172.18.0.0/16",
               "size" : 24
           }
       ]
   }

3. Restart the docker.service service accordingly.
