Using Tag-Based Access Control - Amazon ECR

Using Tag-Based Access Control

The Amazon ECR CreateRepository API action enables you to specify tags when you create the repository. For more information, see Tagging a private repository.

To enable users to tag repositories on creation, they must have permissions to use the action that creates the resource (for example, ecr:CreateRepository). If tags are specified in the resource-creating action, Amazon performs additional authorization on the ecr:CreateRepository action to verify if users have permissions to create tags.

You can used tag-based access control through IAM policies. The following are examples.

The following policy would only allow an IAM user to create or tag a repository as key=environment,value=dev.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "AllowCreateTaggedRepository", "Effect": "Allow", "Action": [ "ecr:CreateRepository" ], "Resource": "*", "Condition": { "StringEquals": { "aws:RequestTag/environment": "dev" } } }, { "Sid": "AllowTagRepository", "Effect": "Allow", "Action": [ "ecr:TagResource" ], "Resource": "*", "Condition": { "StringEquals": { "aws:RequestTag/environment": "dev" } } } ] }

The following policy would allow an IAM user access to all repositories unless they were tagged as key=environment,value=prod.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "ecr:*", "Resource": "*" }, { "Effect": "Deny", "Action": "ecr:*", "Resource": "*", "Condition": { "StringEquals": { "ecr:ResourceTag/environment": "prod" } } } ] }
