Checklist for adding a new Lambda

1. Create the Lambda scaffold

• Copy the template:

  cp -r lambda/_template lambda/<lambda_name>

---

2. Add infrastructure prerequisites (shared stack)

• Add a new ECR repository in:

  infrastructure/terraform/shared/main.tf

• Create a PR to deploy this to main then dev in order to deploy the shared stack

• Verify the ECR repository exists in AWS

---

3. Add Docker build configuration

• Create a Dockerfile for the Lambda
• Verify the Dockerfile path and build context
• Add a new image build job in deploy_terraform.yml using _build_image.yml

---

4. Wire the Lambda deploy job (CI)

• Add a deploy job using _deploy_lambda.yml
• Ensure the deploy job depends on the image build job

---

5. Deploy

• Push changes to GitHub
• CI will:
  1. Build and push the Docker image
  2. Deploy the Lambda
  3. Verify everything deployed. Good things to check:
  • ECR with image
  • SQS
  • Trigger SQS
    • Cloud watch logs

---

5. Delete

1. Delete README if you used cp -r
