docker ps --format '{{.Names}}\t{{.Image}}\t{{.Status}}'
docker compose -f /home/conor/Docker/<stack>/docker-compose.yml ps

Gotchas worth remembering: mailcow serves itself (Caddy does not proxy it), and mynetworks must never trust the bridge gateway 172.29.1.1 (see the 2026-08-16 open-relay entry in [[ops-journal]]).
