Amazon ECR dual-stack endpoints now support AWS PrivateLink

Amazon Elastic Container Registry (ECR) announces AWS PrivateLink support for its dual-stack endpoints. This makes it easier to standardize on IPv6 and enhance your security posture.

Previously, ECR announced IPv6 support for API and Docker/OCI requests via the new dual-stack endpoints. With these dual-stack endpoints, you can make requests from either an IPv4 or an IPv6 network. With today’s launch, you can now make requests to these dual-stack endpoints using AWS PrivateLink to limit all network traffic between your Amazon Virtual Private Cloud (VPC) and ECR to the Amazon network, thereby improving your security posture.

This feature is generally available in all AWS commercial and AWS GovCloud (US) regions at no additional cost. To get started, visit ECR documentation.
