Terraform Module - Cognito User Pools

Author

• Rupert Broad (based on https://github.com/lgallard/terraform-aws-cognito-user-pool)

Description

Creates a Cognito User Pool. If custom DNS name for the authentication endpoint is required then you will also need to create an ACM certificate in us-east-1. This can be done with the terraform-aws-ohp-acm module and an additional provider for the us-east-1 region.

Cognito Identity Providers (IdPs), e.g. Azure can be added using the terraform-aws-ohp-cognito-idp module.
