⚙️ DevOps Skill: Build a Safe Deployment Pipeline A good DevOps engineer does not only deploy code. They make releases predictable, observable, and reversible. Copy this checklist 🚀 DEPLOYMENT SAFETY CHECKLIST Before deploying: 1. Tests pass locally and in CI 2. Linting and formatting pass 3. Secrets are stored in a secret manager 4. Database migration has a rollback plan 5. Infrastructure changes are reviewed 6. Feature flag is ready for risky features During deployment: 7. Deploy to staging first 8. Use gradual rollout where possible 9. Monitor logs, errors, latency, and CPU/memory 10. Confirm health checks pass After deployment: 11. Verify the main user flow 12. Watch error rate for 15–30 minutes 13. Keep the previous version ready 14. Document what changed and how to roll back Rollback rule: If errors rise, latency spikes, or a core flow fails, roll back first, investigate second. GitHub Actions example name: Deploy on: push: branches: [main] jobs: deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Install dependencies run: npm ci - name: Run tests run: npm test - name: Build run: npm run build - name: Deploy run: echo "Add your deployment command here" Tools to learn • Docker — package apps consistently https://github.com/docker • Kubernetes — orchestrate containers https://github.com/kubernetes/kubernetes • GitHub Actions — CI/CD automation https://github.com/features/actions • Terraform — infrastructure as code https://github.com/hashicorp/terraform • Prometheus — metrics and monitoring https://github.com/prometheus/prometheus • Grafana — dashboards and alerts https://github.com/grafana/grafana 📌 Rule: If you cannot roll back safely, you are not ready to deploy.
