DevOps & CI/CD Pipelines for Small Teams: Docker & GitHub Actions

You don't need a 5-person dedicated DevOps team or a complex Kubernetes cluster to deploy web applications like a modern tech company.

With Docker, GitHub Actions, and Docker Compose, small engineering teams can achieve automated testing, staging preview environments, and zero-downtime production deployments for under $50/month in infrastructure costs.

The Lean CI/CD Deployment Workflow

Git Push ──► GitHub Actions ──► 1. Run Pytest & Linting
                                2. Build Multi-Stage Docker Image
                                3. Push to Container Registry
                                4. SSH Deploy to Production VPS
                                5. Run DB Migrations & Health Check

3 Pillars of Lean DevOps

1. Multi-Stage Docker Builds: Keep production images tiny (<100MB) by separating build dependencies from the final runtime container.
2. Automated Pull Request Testing: Run automated unit tests on every pull request to catch bugs before code merges.
3. Automated Database Backups: Schedule nightly encrypted PostgreSQL backups to an isolated S3 bucket with 30-day retention policies.
