%%
%% Amazon Elastic Container Registry (Amazon ECR) is a managed container
%% image registry service.
%%
%% Customers can use the familiar Docker CLI, or their preferred client, to
%% push, pull, and manage images. Amazon ECR provides a secure, scalable, and
%% reliable registry for your Docker or Open Container Initiative (OCI)
%% images. Amazon ECR supports private repositories with resource-based
%% permissions using IAM so that specific users or Amazon EC2 instances can
%% access repositories and images.
%%
%% Amazon ECR has service endpoints in each supported Region. For more
%% information, see Amazon ECR endpoints in the Amazon Web Services General
%% Reference.
