GitHub Actions + AWS Integration
GitHub Actions is GitHub’s CI/CD platform. You write workflows that run on every push, pull request, or schedule. Deploy to AWS directly from your Git repository without external CI/CD tools.
Why GitHub Actions for AWS Deployment?
Built into GitHub
- No separate tool to manage
- Workflows live alongside code in
.github/workflows/ - Approval and review integrated with pull requests
Cost Efficient
- Free for public repos and self-hosted runners
- Generous free tier for private repos (2,000 minutes/month)
AWS Integration
- AWS maintains official GitHub Actions (ECR login, CloudFormation, CodeDeploy)
- Native AWS SDK support
- Deep integration with AWS services
Core Concept: Workflows
Workflows are YAML files that define:
- Trigger: When to run (push, pull request, schedule)
- Jobs: Parallel or sequential work units
- Steps: Commands to execute in each job
- Environment: Server and secrets to use
Example: On push to main, test code, build Docker image, push to ECR, deploy to ECS.
Common GitHub Actions → AWS Patterns
Deploy Lambda on Push
aws-actions/cloudformation-github-deployto update CloudFormation stack- Lambda function code updated automatically
Build & Push Docker to ECR
- Login to ECR with
aws-actions/amazon-ecr-login - Build and push image
- Update ECS service to use new image
Deploy to S3 Static Website
- Build static site (React, Next.js, etc.)
- Sync build output to S3
- Invalidate CloudFront cache
Automated Testing Before Deploy
- Run unit tests, integration tests
- Only deploy if tests pass
- Fail fast on broken code
Authentication: OIDC vs Access Keys
OpenID Connect (Recommended)
- Temporary credentials; no long-lived keys
- Keyless authentication
- Secure and auditable
- Setup: IAM role + OIDC provider configuration
IAM Access Keys (Simpler)
- Store AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY in GitHub Secrets
- Higher risk (long-lived credentials)
- Easier to setup
- Must rotate keys regularly
Workflow Structure
name: Deploy to AWS
on:
push:
branches: [main]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- run: npm test
deploy:
needs: test
runs-on: ubuntu-latest
steps:
- uses: aws-actions/configure-aws-credentials@v4
- run: aws s3 sync build/ s3://my-bucket/Best Practices
Security
- Use OIDC for authentication (not keys)
- Store secrets in GitHub Secrets, not in code
- Require approval before deploying to production
- Rotate credentials regularly
Efficiency
- Cache dependencies (npm, Python packages) to speed up builds
- Use matrix builds to test multiple configurations
- Parallelize jobs when possible
- Only deploy on successful tests
Reliability
- Test before deploying
- Use GitHub Environments for dev/staging/prod
- Implement rollback procedures
- Monitor deployments in CloudWatch

Frequently Asked Questions
How do I authenticate GitHub Actions to AWS?
Use OpenID Connect (OIDC) for keyless authentication. No credentials needed in GitHub secrets. Configure an IAM role with OIDC provider. Alternatively, use IAM user access keys stored as GitHub Secrets (less secure but simpler).
What AWS services can I deploy to from GitHub Actions?
Any AWS service: EC2 (via Systems Manager), ECS, Lambda, CloudFormation, S3, CodeDeploy, Elastic Beanstalk, AppConfig. Use AWS SDKs or AWS CLI in workflow steps to deploy.
How do I deploy a Docker container to ECR from GitHub Actions?
Use `aws-actions/amazon-ecr-login` to login to ECR. Build Docker image with `docker build`. Push to ECR with `docker push`. Update ECS service to use new image.
What are best practices for GitHub Actions + AWS?
Use OIDC for authentication (no credentials in secrets). Keep workflow files DRY (reuse composite actions). Run tests before deploying. Use GitHub Environments for different deployment targets (dev/prod). Cache dependencies for speed.
How do I handle secrets in GitHub Actions for AWS?
Store AWS credentials in GitHub Secrets (Actions > Secrets). Reference with `${{ secrets.SECRET_NAME }}`. For sensitive operations, use GitHub Environments and require approval before deployment.
