fix(deploy): staging NC deploy silently fails (docker-compose v1 ContainerConfig) — switch to v2 + set -e

[ae2079]

Summary

The staging deploy job has been silently failing — reporting green while leaving notification-center stopped. It called docker-compose v1.29.2, which crashes with KeyError: 'ContainerConfig' when recreating a BuildKit-format image (it choked recreating the redis-all dependency of notification-center). Because that crash wasn't the last command in the script — the trailing docker image prune succeeded (exit 0) and there was no set -e — the SSH step exited 0 and the run went green. Net effect: every staging NC deploy did stop → (failed) up → prune and left NC down, invisibly.

NC was silently down on staging from ~Aug 21 (this is why owner notification emails, incl. the #426/#458 project-listed emails, stopped arriving) until I restarted it manually today.

Evidence — the green Aug-21 run's deploy step:

docker-compose stop notification-center      -> Stopping ... done   (NC stopped)
docker-compose pull notification-center       -> done
docker-compose up -d notification-center      -> ERROR: for redis-all 'ContainerConfig'
                                                 KeyError: 'ContainerConfig'   (crash; NC not restarted)
docker image prune -a --force                 -> done                (exit 0 -> run goes GREEN)

Changes

• Use docker compose v2 instead of docker-compose v1.29.2. The staging host already has v2 (v2.40.0) installed, and the prod/main pipeline already uses v2 — v2 has no ContainerConfig bug.
• Add set -e so a failed deploy fails red instead of being masked by the trailing prune.
• Pin -f docker-compose.staging.yml so the deployed image tag is deterministic (not dependent on an ambient COMPOSE_FILE).
• Add --no-deps so the deploy doesn't recreate/churn the shared redis-all container.
• Drop the separate stop (v2's up -d recreates atomically), removing the stop-then-fail window.

Notes

• No server change was needed — v2 was already installed; the pipeline was just invoking the old v1 binary. NC is already back up on staging (restarted manually).
• The prod (main) pipeline uses v2 so it isn't hit by the crash, but it still lacks set -e — a failed prod deploy would likewise go green silently. Worth the same set -e + --no-deps hardening in a follow-up.

How to test

Merge to staging and watch the run. The deploy step should end with NC Up (verify: docker ps | grep notification-center), and any real failure should now turn the run red rather than green.

Summary by CodeRabbit

• Chores
  • Hardened staging deployment permissions by limiting access to only what each workflow step requires.
  • Improved deployment reliability by allowing non-critical image cleanup failures without interrupting successful deployments.
  • Continued using Docker Compose v2 for staging deployments.
  • Streamlined staging updates to refresh only the notification service without restarting dependencies.

Walkthrough

The staging workflow now uses job-specific GITHUB_TOKEN permissions. Testing has read-only repository access, image publication can write packages, and SSH deployment has no token permissions. Image pruning is now best-effort.

Changes

Staging workflow

Layer / File(s)	Summary
Job-specific token permissions .github/workflows/staging-pipeline.yml	The workflow denies token permissions by default. The test job can read repository contents. The publish job can read contents and write packages. The deploy job has no token permissions.
Best-effort deployment cleanup .github/workflows/staging-pipeline.yml	The SSH deployment pulls and recreates only notification-center with Docker Compose v2. Image-prune errors are reported without failing an otherwise successful deployment.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 72947

The staging deployment changes are localized to deployment command handling and failure propagation; no actionable merge-blocking risk remains beyond normal checks and review.

Poem

A rabbit locks each token tight,
Grants the jobs the needed right.
One service hops into the fray,
Cleanup may stumble, not deployment’s day.
Staging rests in safer hay. 🐇

In @.github/workflows/staging-pipeline.yml:
- Line 95: Update the deployment workflow’s image cleanup command so docker
image prune -a --force is best effort and cannot cause the SSH step to fail
after a successful deployment, while preserving failure handling for the
deployment itself.
- Around line 95-106: Declare workflow-level permissions as empty, grant the
test job contents: read for actions/checkout, and grant the publish job
contents: read plus packages: write for checkout and GHCR publishing. Keep the
deploy job permissions explicitly empty.
