Complete CI/CD Pipeline for Startups: GitHub Actions + Docker + AWS

Architecture: Code push to GitHub triggers Actions, tests run, Docker image builds, image pushes to ECR, ECS task updates, rolling deployment with health checks. Step 1 — CI on PRs: Run lint, unit tests, integration tests, Docker build on every Pull Request. Step 2 — CD to Staging: Merge to main triggers AWS OIDC auth, Docker build tagged with git SHA, ECS task definition update, rolling deployment to staging. Step 3 — Production Gate: Manual approval or automated E2E tests on staging required before production deploy. GitHub Environments with protection rules. Step 4 — Zero Downtime: ECS rolling update with min_healthy_percent 100. New tasks start before old ones stop. Step 5 — Rollback: Re-deploy previous ECR image tag. Takes under 2 minutes. Result: Deploy to production multiple times per day with confidence.

Strategic Implementation

Establishing a robust workflow is paramount in 2026. As the gap between development and operations continues to shrink, the tools we choose must facilitate speed WITHOUT sacrificing security or stability.
