Add an internal/compose package that discovers Compose projects via
`docker compose ls` + `docker ps` labels (grouped by
com.docker.compose.project/service) and enriches each container with
`docker inspect` ports/mounts and Traefik router labels. Management
runs `docker compose` in each project's working directory for
up/down/stop/restart/pull plus per-service variants and log tails.
Wire it into the webapp: a 60s ComposeRefresher (constructed in New,
started in Start, stopped in Close), a /compose list + detail + logs
HTML surface, and /web/api/compose/* JSON endpoints (list, detail,
logs, project/service lifecycle). Browser lifecycle POSTs are
session+CSRF protected; the /web/api/* variants accept HTTP basic auth.
WORKER_COMPOSE_ENABLED defaults on (false to disable).
Tests cover discovery parsing/grouping/traefik/summary, the action
allowlists, and the full handler surface (list/detail/logs HTML+API,
CSRF enforcement, disabled/unknown-action rejection, audit writes,
success+failure exec paths) via a stub Docker binary.
- reconnect safely after token rotation and retry leased results
- reject malformed tasks and remove production cluster debug mutation
- validate environment files and require immutable container images
BREAKING CHANGE: Docker install, deploy, and Compose now require an
immutable repository@sha256 image reference.
Normalize registry and release tag references before Buildx runs. Use process-local liveness so a control-plane outage does not restart a healthy worker container.
