AWS Lambda GitHub Actions Function Deployment Demo

It is now possible to automatically deploy AWS Lambda functions with GitHub Actions when code or configuration changes are pushed to a GitHub repository.

AWS Lambda now supports GitHub Actions to simplify function deployment

This feature eliminates the need for cumbersome steps such as custom scripts and packaging.

This demo project is designed to try out this new capability.

Initial Setup

1. Copy terraform.tfvars.example to create terraform.tfvars:

   github_org  = "your-github-username"
   github_repo = "aws-lambda-github-actions-function-deployment-demo"
   

2. Deploy infrastructure with Terraform:

   cd terraform
   
   terraform init
   terraform plan
   terraform apply

   At this point, the Lambda function doesn't include Python packages, so executing the Lambda will result in an error.

3. Set AWS_ROLE_TO_ASSUME in GitHub repository Secrets:

   AWS_ROLE_TO_ASSUME = <github_actions_deploy_role_arn from terraform output>
   

4. Set AWS_REGION in GitHub repository Variables:

   AWS_REGION = <any region you want to use>
   

5. Push code to GitHub repository to trigger GitHub Actions and deploy Lambda code

After Initial Setup

• Deployment is triggered only when files in the src/ folder are changed
• Manual execution is possible with workflow_dispatch
• Changes to Terraform files and other files won't trigger unnecessary deployments
