Amazon Elastic Container Registry (ECR) supports image replication between the AWS GovCloud (US) Region

Amazon Elastic Container Registry (ECR) now supports the ability to replicate images in private ECR repositories across accounts and/or regions, between the AWS GovCloud (US) Regions. Storing images helps applications start up faster as image download time is reduced due to lower latency from in-region pulls. Geographically dispersed images also help you meet backup and disaster recovery requirements for your applications. Amazon ECR Replication feature provides a simple and reliable way to replicate images, and eliminates the operational burden of manually pushing images across multiple regions and accounts.

With a few clicks in the Amazon ECR Console, or using the Amazon CLI, you can specify the destination account and/or region for a source repository. Once replication is turned on, ECR will automatically replicate all new images pushed in source repository to the destination region. Additionally, ECR offers granular control to replicate specific repositories. You can use repository name prefixes as filters to specify which repositories to replicate. To learn more about using replication in ECR, see our documentation.
