%%
%% Amazon Elastic Container Registry Public (Amazon ECR Public) is a managed
%% container image registry service.
%%
%% Amazon ECR provides both public and private registries to host your
%% container images. You can use the Docker CLI or your 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 public repositories with this API. For
%% information about the Amazon ECR API for private repositories, see Amazon
%% Elastic Container Registry API Reference.

%% @doc Checks the availability of one or more image layers that are within a

%% image layer is skipped.
%%
%% This operation is used by the Amazon ECR proxy and is not generally used
%% by customers for pulling and pushing images. In most cases, you should use
%% the `docker' CLI to pull, tag, and push images.
