# =====================================================================
#  Checkmk + NGINX Proxy Manager
#  Funktioniert identisch mit:  docker compose  |  podman-compose
#
#  - Beide Dienste laufen im Host-Netzwerk  -> keine "ports:"-Definition
#  - Ausschliesslich Bind-Mounts nach ./data  -> keine named volumes
# =====================================================================
