container_name: openwa-docker-proxy
restart: unless-stopped
# Only on the isolated internal network — reachable solely by openwa-api, NOT the
# dashboard or any other peer. `internal: true` also denies the proxy
# outbound access; it only needs the locally-mounted docker socket.

environment:
# Minimal set that keeps DockerService (src/modules/docker/docker.service.ts) working:
# PING (health), INFO (getSystemInfo), CONTAINERS (list/inspect/create/start/stop),
# IMAGES (pull), VOLUMES (createVolume). POST is the proxy's single all-or-nothing
