Private images in Amazon ECR

Amazon ECR stores Docker images, Open Container Initiative (OCI) images, and OCI compatible artifacts in private repositories. You can use the Docker CLI, or your preferred client, to push and pull images to and from your repositories.

With Amazon ECR support for OCI v1.1, you can store and manage reference artifacts that are defined by the OCI Referrers API. Artifacts include signatures, Software Bill of Materials (SBoMs), Helm charts, scan results, and attestations. A set of artifacts for a container image is transferred with that container and stored as a separate image that counts as an image consumed for your repository.

The Signing an image stored in an Amazon ECR private repository and Deleting signatures and other artifacts from an Amazon ECR private repository pages provide examples of how to use signature-related artifacts. For more information on signing container images, see Signing container images in the AWS Signer Developer Guide.
