upload-layer-part¶

Description¶

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 (or about 20MB). The UploadLayerPart API is called once per each new image layer part.

Note

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.

Synopsis¶

  upload-layer-part
[--registry-id <value>]
--repository-name <value>
--upload-id <value>
--part-first-byte <value>
--part-last-byte <value>
--layer-part-blob <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--registry-id (string)

The Amazon Web Services account ID associated with the registry to which you are uploading layer parts. If you do not specify a registry, the default registry is assumed.

--repository-name (string)

The name of the repository to which you are uploading layer parts.

--upload-id (string)

The upload ID from a previous InitiateLayerUpload operation to associate with the layer part upload.

--part-first-byte (long)

The position of the first byte of the layer part witin the overall image layer.

--part-last-byte (long)

The position of the last byte of the layer part within the overall image layer.

--layer-part-blob (blob)

The base64-encoded layer part payload.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To upload a layer part

This following upload-layer-part uploads an image layer part to the layer-test repository.

aws ecr upload-layer-part \
    --repository-name layer-test \
    --upload-id 6cb64b8a-9378-0e33-2ab1-b780fab8a9e9 \
    --part-first-byte 0 \
    --part-last-byte 8323314 \
    --layer-part-blob fileb:///var/lib/docker/image/overlay2/layerdb/sha256/ff986b10a018b48074e6d3a68b39aad8ccc002cdad912d4148c0f92b3729323e/layer.b64

Output:

{
    "uploadId": "6cb64b8a-9378-0e33-2ab1-b780fab8a9e9",
    "registryId": "012345678910",
    "lastByteReceived": 8323314,
    "repositoryName": "layer-test"
}

Output¶

registryId -> (string)

The registry ID associated with the request.

repositoryName -> (string)

The repository name associated with the request.

uploadId -> (string)

The upload ID associated with the request.

lastByteReceived -> (long)

The integer value of the last byte received in the request.
