CI/CD Best Practices with GitHub Actions and AWS

A production-grade CI/CD pipeline does more than run tests and deploy. It enforces security gates, manages secrets, handles rollbacks, and provides full audit trails.

GitHub Actions has become the de-facto CI/CD platform for teams deploying to AWS. Its native integration with GitHub repositories, generous free tier, and flexible action marketplace make it a natural choice.

Pipeline Structure

Every production pipeline should have three distinct stages: Build & Test, Staging Deploy, and Production Deploy. The staging deploy should be automated. The production deploy should require a manual approval gate or be triggered only on tagged releases.

Secret Management

Never store AWS credentials as GitHub Secrets. Instead, use OIDC federation to let GitHub Actions assume an IAM role without long-lived credentials. This is both more secure and easier to audit.

- uses: aws-actions/configure-aws-credentials@v4
  with:
    role-to-assume: arn:aws:iam::123456789012:role/GitHubActions
    aws-region: us-east-1

Blue/Green Deployments

Use ECS Blue/Green deployments via CodeDeploy for zero-downtime deploys with automatic rollback on health check failure. This is the safest deployment strategy for production services.
