CI/CD Troubleshooting

A seven-stage promotion path. Failed tests and scans do not publish. A failed rollout is not automatically a total outage. Rollback is explicit.

Pipeline idle Every gate passed. The same digest is what staging and production should run. Ready 3/3. No published digest.

Fix and rerun is available after a failed gate. Rollback is only available after a failed rollout that still has a previous digest.

commit Idle. Choose a scenario and run the pipeline.

ASSUMPTIONS AND LIMITS

One artifact digest is built once. Recovery never silently rebuilds for production.
Policy is a teaching gate: critical exposed findings block publish.
Deploy failure means readiness did not pass. Some previous replicas may still serve traffic.
