This checklist guides engineers through setting up a secure, test-driven CI/CD pipeline—from secrets to deploy and rollback. It’s aimed at DevOps engineers, SREs, and teams who want reliable, auditable automated deployments.

  1. Initialize repository and define branch strategy — Create main/develop/feature branches and enforce branch protection rules.
  2. Add CI/CD pipeline configuration file — Create pipeline YAML (e.g., .github/workflows/ci.yml) and validate syntax locally.
  3. Store secrets in a secure secrets store — Use repo secrets or a vault; never commit credentials or plaintext keys.
  4. Add CI quality checks
  5. Add lint job to pipeline — Run lint on PRs and fail fast to keep code consistent.
  6. Add unit test job to pipeline — Run unit tests with coverage and parallelize where possible.
  7. Build and publish artifacts
  8. Add build job and cache dependencies — Produce reproducible artifacts and enable caching for speed.
  9. Build Docker image and tag appropriately — Tag images with commit SHA and semantic version where possible.
  10. Push Docker image to registry using stored creds — Authenticate with least-privileged credentials and push immutable tags.
  11. Scan Docker image for vulnerabilities — Use scanners like Trivy or Clair and fail builds on critical findings.
  12. Deploy and test in staging
  13. Deploy to staging environment — Deploy using manifests, Helm, or Terraform; use a dedicated staging namespace.
  14. Run automated staging smoke tests — Check critical endpoints, auth, and health endpoints in staging.
  15. Add manual approval gate for production deploy — Require a human approval step or approval PR before production rollout.
  16. Deploy to production after approval — Use rolling or canary deployments and respect maintenance windows.
  17. Run production smoke tests and health checks — Run lightweight checks and verify metrics, logs, and traces.
  18. Configure notifications for pipeline events — Send build failures and deploy results to Slack, email, or PagerDuty.
  19. Implement automatic rollback procedure — Define triggers and steps to rollback to the previous stable release.
  20. Document runbook and emergency contacts — Include commands, rollback steps, and on-call phone/emails.
  21. Monitor metrics and set alerts for deploys — Track error rate, latency, and traffic; set alert thresholds.
  22. Review and iterate on the pipeline configuration — Schedule periodic reviews to update tests, tooling, and permissions.
