Provides common functionality for Custom resources in CloudFormation.

Summary

• Helper to enable all types of resource types for create/update/read/list operations
• Heavily inspired to use dynamodb for resource management. Supports all native create/read/update/list/delete operations for any resource.
• Dynamic identifier generation to support any resource identifier use case. Read Only resources or real resource creation.

Required extra permissions in each handlers permissions:

• Due to us using dynamodb as a backend, we need extra permissions to store/retrieve state information from dynamo. These permissions should be added in addition to any other required permissions by each handler.

  • dynamodb:CreateTable
  • dynamodb:PutItem
  • dynamodb:DeleteItem
  • dynamodb:GetItem
  • dynamodb:UpdateItem
  • dynamodb:UpdateTable
  • dynamodb:DescribeTable
  • dynamodb:Scan

   poetry --version
   poetry add boto3
  
   poetry add --group dev  pytest
  
   poetry install --no-root

• Generating Stubs after all 3rd party stubs are installed

  find src/ -type f -name '*.pyi' -exec rm {} +
  stubgen src/ -o src/  --include-private 
  

  • Do not run again after manually changed.
  • Build system updated to validate stubs via stubtest
