Description

During the creation of a repository on an Amazon Elastic Container Registry (ECR) it would be very helpful to have a way to retrieve the login credential for the newly created registry. I've noticed two related pull requests (#3145, #2824) that propose a new data source to retrieve this information, but they appeared to be closed without being merged to master.

What is the reason why those pull requests were closed? Is there a better way to retrieve the login credentials?

My use case is the following:

1. Create a new repository using aws_ecr_repository
2. Get the login credentials for the registry that contains the repository created above
3. Pass the credential to external scripts that push some image to the repository

For now, as a workaround, I pass the registry id to my script and then I get the credentials using a library to interface with the API for AWS (boto3 in my case), I log in to the registry and finally push the image. The goal is to remove the needs to use AWS API in my script.

Thanks in advance.

  value    = "${aws_ecr_repository.dummy_repo.registry_credentials}"
  description    = "Returns the login credentials for the registry that contains the specified repository" 
}
