Amazon web services – How to import existing ECR repository into Terraform

I’ve tried variations of the following tf file after reading these docs: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ecr_repository to import an existing ECR repository.

import {
  to = aws_ecr_repository.tamarack_api
  id = "arn:aws:ecr:us-west-2:xxxxxxxxxxxx:repository/tamarack-api"
}

resource "aws_ecr_repository" tamarack_api {
  name = "tamarack-api"
}

terraform plan gives me this error:

Error: reading ECR Repository (arn:aws:ecr:us-west-2:xxxxxxxxxxxx:repository/tamarack-api): InvalidParameterException: Invalid parameter at ‘repositoryName’ failed to satisfy constraint: ‘must satisfy regular expression ‘(?:[a-z0-9]+(?:[.-][a-z0-9]+)/)[a-z0-9]+(?:[.-][a-z0-9]+)*”

I tried that regex in https://regex101.com/ using the Go language, but it matches the string tamarack-api. Thanks for any help with this!

    Name is only tamarack-api, not arn:aws:ecr:us-west-2:xxxxxxxxxxxx:repository/tamarack-api.

    If a resource reference includes this arn:aws:ecr:us-west-2:xxxxxxxxxxxx: part then it is actually the ARN not the name. This VPC resource is a good example. The name of the VPC is like a tag, the ID is something like vpc-abcdef and the ARN would look like arn:aws:ecr:us-west-2:xxxxxxxxxxxx:.

    It’s helpful to know because some resources will allow you to have duplicate names but the ARN is always unique.
