Docker / Compose, Swarm & Production Security
Validate a Compose batch job's outcome beyond container exit status
A one-shot project service can complete while its external work remains partial or incorrect. Inspect its lifecycle and expected artifacts.
Environment and inputs: Docker Engine · Compose v2 and Buildx where specified; Linux containers unless noted. Verify daemon context, installed feature support and authorized host or Swarm manager access first.
Start with this check
Confirm the environment and replace sample objects, namespaces, images, paths and hosts with approved targets. Share only relevant, sanitized output. Follow the workload owner’s process for changes.
docker compose ps -aRead the result
The listing includes stopped project containers and recorded state. It does not reconcile business records, external transactions or complete historical logs.
Resolve and verify
Match the run identity and exit handling with the application's result contract. Verify intended outputs and safe retry semantics before an approved rerun.
Before changing production
Do not interpret every zero exit as complete business success or repeat non-idempotent jobs blindly.
