Basic traefik role with sane defaults that you can apply with a one-liner:
# Deploy with staging certificates by default to not blacklist your domain
# in case of configuration mistake
bigsudo yourlabs.traefik @example.com --become -v domain=example.com email=your@email
# For production certificates
bigsudo yourlabs.traefik @example.com --become -v acme=prod domain=example.com email=your@email
Note that the dashboard will be served in https://traefik.<domain>,
protected by http basic auth with user "root" and password: shown by bigsudo at
the end of role, and also available in /root/password_root
Note that it should remember the vars that you pass on the CLI because it writes an ansible fact file.
