API Gateway - What is needed?
- API
- Permission
- S3
- Stage
- Mapping
CloudFormation
- Templates for AWS Infrastructure
- Parameters -> Resources -> Output
- Version Control, Change Sets
- A bit like docker compose
- json/yaml
CloudFormation issues
- Lambda needs code within S3
- API Gateway needs Swagger File within S3
CloudFormation solution
- Small initial Stack including S3
- Upload files
- Apply ChangeSet with Lambda and API Gateway
- or
- package (needs S3 again)
