This sample contains an AWS AppConfig Extension which verifies that specified AWS Systems Manager Change Calendars are open before proceeding with the deployment.
The Lambda function for the extension itself is in lambda/index.py; the CDK
stack is here to deploy it with the correct IAM permissions, and create an
AppConfig Extension.
Please see the AWS AppConfig documentation for details on configuring the service.
Please see the Systems Manager Change Calendar documentation for details on setting up Change Calendars.
Ensure you have an up-to-date Python install available, and AWS CDK v2 installed.
You will need Docker installed and running for CDK to build the Lambda function.
