Amazon ECR service-linked role for replication

Service-linked role permissions for Amazon ECR

Amazon ECR uses service-linked roles named AWSServiceRoleForECRReplication – Allows Amazon ECR to replicate images across multiple accounts..

The AWSServiceRoleForECRReplication service-linked role trusts the following services to assume the role:

• replication.ecr.amazonaws.com

The following ECRReplicationServiceRolePolicy role permissions policy allows Amazon ECR to use the following actions on resources:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ecr:CreateRepository",
                "ecr:ReplicateImage"
            ],
            "Resource": "*"
        }
    ]
}

Note

The ReplicateImage is an internal API that Amazon ECR uses for replication and can't be called directly.

You must configure permissions to allow an IAM entity (for example a user, group, or role) to create, edit, or delete a service-linked role. For more information, see Service-Linked Role Permissions in the IAM User Guide.

Creating a service-linked role for Amazon ECR

You don't need to manually create the Amazon ECR service-linked role. When you configure replication settings for your registry in the AWS Management Console, the AWS CLI, or the AWS API, Amazon ECR creates the service-linked role for you.

If you delete this service-linked role and need to create it again, you can use the same process to recreate the role in your account. When you configure replication settings for your registry, Amazon ECR creates the service-linked role for you again.

Editing a service-linked role for Amazon ECR

Amazon ECR doesn't allow manually editing the AWSServiceRoleForECRReplication service-linked role. After you create a service-linked role, you can't change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see Editing a service-linked role in the IAM User Guide.

Deleting the service-linked role for Amazon ECR

If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way, you don’t have an unused entity that isn't actively monitored or maintained. However, you must remove the replication configuration for your registry in every Region before you can manually delete the service-linked role.

Note

If you try to delete resources while the Amazon ECR service is still using the roles, your delete action might fail. If that happens, wait for a few minutes and try again.

To delete Amazon ECR resources used by the AWSServiceRoleForECRReplication

1. Open the Amazon ECR console at https://console.aws.amazon.com/ecr/.

2. From the navigation bar, choose the Region your replication configuration is set on.

3. In the navigation pane, choose Private registry.

4. On the Private registry page, on the Replication configuration section, choose Edit.

5. To delete all of your replication rules, choose Delete all. This step requires confirmation.

To manually delete the service-linked role using IAM

Use the IAM console, the AWS CLI, or the AWS API to delete the AWSServiceRoleForECRReplication service-linked role. For more information, see Deleting a Service-Linked Role in the IAM User Guide.
