Amazon ECR Repository Policy Examples

The following examples show policy statements that you could use to control the permissions that users have to Amazon ECR repositories.

Important

Amazon ECR users require permissions to call ecr:GetAuthorizationToken before they can authenticate to a registry and push or pull any images from any Amazon ECR repository. Amazon ECR provides several managed policies to control user access at varying levels; for more information, see Amazon ECR Managed Policies.

Example: Allow IAM Users Within Your Account

The following repository policy allows IAM users within your account to push and pull images.

Copy
{ "Version": "2008-10-17", "Statement": [ { "Sid": "AllowPushPull", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::aws_account_id:user/push-pull-user-1", "arn:aws:iam::aws_account_id:user/push-pull-user-2" ] }, "Action": [ "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage", "ecr:BatchCheckLayerAvailability", "ecr:PutImage", "ecr:InitiateLayerUpload", "ecr:UploadLayerPart", "ecr:CompleteLayerUpload" ] } ] }

Example: Allow Other Accounts

The following repository policy allows a specific account to push images.

Copy
{ "Version": "2008-10-17", "Statement": [ { "Sid": "AllowCrossAccountPush", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::aws_account_id:root" }, "Action": [ "ecr:GetDownloadUrlForLayer", "ecr:PutImage", "ecr:InitiateLayerUpload", "ecr:UploadLayerPart", "ecr:CompleteLayerUpload" ] } ] }

The following repository policy allows all AWS accounts to pull images.

Copy
{ "Version": "2008-10-17", "Statement": [ { "Sid": "AllowPull", "Effect": "Allow", "Principal": "*", "Action": [ "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage", "ecr:BatchCheckLayerAvailability" ] } ] }

The following repository policy allows some IAM users to pull images (pull-user-1 and pull-user-2) while providing full access to another (admin-user).

Note

For more complicated repository policies that are not currently supported in the AWS Management Console, you can apply the policy with the set-repository-policy AWS CLI command.

Copy
{ "Version": "2008-10-17", "Statement": [ { "Sid": "AllowPull", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::aws_account_id:user/pull-user-1", "arn:aws:iam::aws_account_id:user/pull-user-2" ] }, "Action": [ "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage", "ecr:BatchCheckLayerAvailability" ] }, { "Sid": "AllowAll", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::aws_account_id:user/admin-user" }, "Action": [ "ecr:*" ] } ] }

Example: Deny All

The following repository policy denies all users the ability to pull images.

Copy
{ "Version": "2008-10-17", "Statement": [ { "Sid": "DenyPull", "Effect": "Deny", "Principal": "*", "Action": [ "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage", "ecr:BatchCheckLayerAvailability" ] } ] }
