## 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
