Automating AWS Lambda Deployments with GitHub Actions

The article Automating AWS Lambda Deployments with GitHub Actions by Iván Gómez Arnedo explains how to set up a CI/CD pipeline for AWS Lambda using GitHub Actions. This approach automates deployments whenever source code changes, reducing manual intervention and ensuring consistency.

You Should Know:

1. Setting Up GitHub Actions for AWS Lambda

To automate AWS Lambda deployments, follow these steps:

1. Create a GitHub Actions Workflow File (`deploy.yml`):

name: Deploy AWS Lambda 
on: 
push: 
branches: [ main ] 
jobs: 
deploy: 
runs-on: ubuntu-latest 
steps: 
- uses: actions/checkout@v4 
- uses: actions/setup-node@v4 
- run: npm install 
- run: zip -r function.zip . 
- uses: aws-actions/configure-aws-credentials@v4 
with: 
aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }} 
aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }} 
aws-region: us-east-1 
- run: aws lambda update-function-code --function-name MyLambda --zip-file fileb://function.zip 

1. Store AWS Credentials in GitHub Secrets (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY).

2. Using OpenID Connect (OIDC) for Secure AWS Access
   Instead of hardcoding credentials, use OIDC for temporary tokens:

   </p></li>
   </ol>
   
   <p>- uses: aws-actions/configure-aws-credentials@v4 
   with: 
   role-to-assume: arn:aws:iam::123456789012:role/GitHubActionsRole 
   aws-region: us-east-1 
   

   3. AWS SAM Integration for Advanced Deployments

   AWS Serverless Application Model (SAM) provides better control:

    Install AWS SAM CLI 
   pip install aws-sam-cli
   
   Build and Deploy 
   sam build 
   sam deploy --guided 
   

   4. Multi-Stage Deployments (Dev/QA/Prod)

   Use GitHub Environments and workflow conditions:

   jobs: 
   deploy: 
   environment: production 
   if: github.ref == 'refs/heads/main' 
   

   5. Testing Before Deployment

   Add unit tests in the workflow:

   - run: npm test 
   

   What Undercode Say

   Automating AWS Lambda deployments with GitHub Actions improves efficiency and reduces errors. Key takeaways:
   – Use OIDC instead of static credentials.
   – Leverage AWS SAM for complex serverless apps.
   – Implement multi-stage deployments for safer releases.
   – Always test before deploying to avoid runtime issues.

   Expected Output:

   A fully automated AWS Lambda deployment pipeline using GitHub Actions, secured via OIDC, with multi-stage testing and AWS SAM integration.
