Today, Amazon Elastic Container Registry (ECR) launched the ability to replicate specific repositories to accounts or regions, and see when images were replicated through the ECR API. This gives you granular control to replicate images within repositories you want, instead of replicating all images in a registry, and the ability to automate actions through the new DescribeImageReplicationStatus API whenever images are replicated.

To get started, you can specify which repositories to replicate with a prefix within the AWS Management Console or PutReplicationConfiguration API. For example, the prefix “prod” would replicate repositories named prod-1 or prod-app, but not test-app. See the full documentation here and walk-through in the blog post here.
