Once you execute the above command, you'll be dropped into a `/work` directory inside a Docker container. The `/work` directory contains the playbook's code.
The above command tries to mount an SSH key (`$HOME/.ssh/id_ed25519`) into the container (at `/root/.ssh/id_ed25519`). If your SSH key is at a different path (not in `$HOME/.ssh/id_ed25519`), adjust that part.
