Use existing Cognito User pool with amplify auth

Hi, I’m working on an android project with amplify. I find it very powerful but it also hides lot of complexity. So…

Is it possible to use amplify with an existing Cognito User pool I already configured.

amplify add auth (I would like to specify my own user pool and not create a new one)

This is already possible for appsync amplify add codegen --apiId XXXXXXXXXXXXXXXXXXXXXXXX

More generally I would like to swith my configuration from dev to prod env

Thanks,

Hey guys, if you want to use an already configured user pool, you can manually add it to your client-side code. For more details, look at - https://aws-amplify.github.io/docs/js/authentication#manual-setup

Amplify CLI uses Cloudformation to deploy and manage resources and unfortunately, Cloudformation doesn’t allow you to manage existing resources, so you won’t be able to manage an already existing resource using the Amplify CLI for now.

in my use case, we’re tying do modularize the project so that any new amplify projects could use the same Cognito pool that’s already setup. example, we have 2 API endpoints (userdata and payment), we’d like development of those APIs to be independent (separate teams, separate repository), but have them still share the same Cognito to allow all the @auth transform directives to work in the GQL schema with this existing AUTH endepoint

ideally we’d be able to do

amplify add auth --poolARN arn:aws:cognito-idp:eu-west-1:500880489372:userpool/eu-west-1_4DFTecsHs

the current amplify project does not need to load all the configuration and redeploy the AUTH component, but can still use this configuration to automatically set the Amplify API with relevant information.
