Amazon Elastic Container Registry Public

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

Method Detail

batchCheckLayerAvailability

BatchCheckLayerAvailabilityResult batchCheckLayerAvailability(BatchCheckLayerAvailabilityRequest batchCheckLayerAvailabilityRequest)

Checks the availability of one or more image layers within a repository in a public registry. When an image is pushed to a repository, each image layer is checked to verify if it has been uploaded before. If it has been uploaded, then the 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.

Parameters:

batchCheckLayerAvailabilityRequest -

Returns:

Result of the BatchCheckLayerAvailability operation returned by the service.

Throws:

RepositoryNotFoundException - The specified repository could not be found. Check the spelling of the specified repository and ensure that you are performing operations on the correct registry.

InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.

ServerException - These errors are usually caused by a server-side issue.

RegistryNotFoundException - The registry does not exist.

AWS API Documentation

batchDeleteImage

BatchDeleteImageResult batchDeleteImage(BatchDeleteImageRequest batchDeleteImageRequest)

Deletes a list of specified images within a repository in a public registry. Images are specified with either an imageTag or imageDigest.

You can remove a tag from an image by specifying the image's tag in your request. When you remove the last tag from an image, the image is deleted from your repository.

You can completely delete an image (and all of its tags) by specifying the image's digest in your request.

Parameters:

batchDeleteImageRequest -

Returns:

Result of the BatchDeleteImage operation returned by the service.

Throws:

ServerException - These errors are usually caused by a server-side issue.

CompleteLayerUploadResult completeLayerUpload(CompleteLayerUploadRequest completeLayerUploadRequest)

Informs Amazon ECR that the image layer upload has completed for a specified public registry, repository name, and upload ID. You can optionally provide a sha256 digest of the image layer for data validation purposes.

When an image is pushed, the CompleteLayerUpload API is called once per each new image layer to verify that the upload has completed.

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.

InvalidLayerException - The layer digest calculation performed by Amazon ECR upon receipt of the image layer does not match the digest specified.

LayerPartTooSmallException - Layer parts must be at least 5 MiB in size.

LayerAlreadyExistsException - The image layer already exists in the associated repository.

EmptyUploadException - The specified layer upload does not contain any layer parts.

shutdown

void shutdown()

Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:

request - The originally executed request.

Returns:

The response metadata for the specified request, or null if none is available.
