Amazon ECR dual-stack endpoints now support Amazon PrivateLink
Amazon Elastic Container Registry (ECR) announces PrivateLink support for its dual-stack endpoints. This makes it easier to standardize on IPv6 and to 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 the dual-stack endpoints using Amazon PrivateLink to limit all network traffic between your VPC and ECR to the Amazon network, improving your security posture.
This feature is generally available in the Amazon Web Services China Regions at no additional cost, including Amazon Web Services China (Beijing) region, operated by Sinnet and Amazon Web Services China (Ningxia) region, operated by NWCD. To get started, visit ECR documentation.
