UPDATE: CloudFormation now natively supports creation of Cognito Domain, Resources and Client ids. So this code should be used for references purposes only.
This repository contains sample Lambda functions that handle creating Cognito resources that are currently not supported by CloudFormation. These Cognito resources are:
- Cognito Domain
- Cognito Resource Server
- Cognito AppClient Id
As the changes are made to the Cognito CloudFormation templates, custom resource Lambda function takes care of automatically updating (creating/deleting) the underlying resources (listed above).
The code uses crhelper library from aws blog post.
In order to deploy the custom resources, run deploy.sh script in cloudformation folder. This script only executes when following environment variables are set:
- AWS_PROFILE
- AWS_REGION
- AWS_CLI_BIN
Set AWS_PROFILE environment to point to your AWS account. Set AWS_REGION appropriately for your account. Finally, set AWS_CLI_BIN to the fully qualified path of your AWS CLI binary.
The tear-down script is available in cloudformation/undeploy.sh. Simply execute this script to undeploy all stacks. Make sure that infra S3 buckets are empty.
