=== Post installation message from docker-rootless ===
This is based on https://docs.docker.com/engine/security/rootless/
To Run the Docker daemon as a non-root user (Rootless mode) for ArchLinux, you need to do the following things:

1. Configure subuid and subgid

Create '/etc/subuid' and '/etc/subgid' with the following:

    testuser:231072:65536
    # replace 'testuser' with your username.

2. Enable socket-activation for the user service:

    systemctl --user enable --now docker.socket

3. Finally set docker socket environment variable:

    export DOCKER_HOST=unix://\$XDG_RUNTIME_DIR/docker.sock

You can also add it to '~/.bashrc' or somewhere alike.
