# Amazon Elastic Container Registry Public ## API Docs - Root [/](https://apidog.com/apidoc/docs-site/345211/api-3477004.md):
Checks the availability of one or more image layers that are 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.
Deletes a list of specified images that are 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 digest of the image in your request.

digest of the image layer for data validation purposes.
When an image is pushed, the CompleteLayerUpload API is called once for each new image layer to verify that the upload is complete.

Beginning with Docker version 1.9, the Docker client compresses image layers before pushing them to a V2 Docker registry. The output of the docker images
command shows the uncompressed image size. Therefore, it might return a larger image size than the image sizes that are returned by DescribeImages.

When an image is pushed, the InitiateLayerUpload API is called once for each image layer that hasn't already been uploaded. Whether an image layer uploads is determined by the BatchCheckLayerAvailability API action.
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.
Creates or updates the image manifest and tags that are associated with an image.
When an image is pushed and all new image layers have been uploaded, the PutImage API is called once to create or update the image manifest and the tags that are associated with the image.
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.
resourceArn
. If existing tags on a resource aren't specified in the request parameters, they aren't changed. When a resource is deleted, the tags associated with that resource are also deleted.

- Root [/](https://apidog.com/apidoc/docs-site/345211/api-3477026.md): Uploads an image layer part to Amazon ECR.
When an image is pushed, each new image layer is uploaded in parts. The maximum size of each image layer part can be 20971520 bytes (about 20MB). The UploadLayerPart API is called once for each new image layer part.
