describe_images

describe_images(**kwargs)

Returns metadata that's related to the images in a repository in a public registry.

Note

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.

Request Syntax

response = client.describe_images(
    registryId='string',
    repositoryName='string',
    imageIds=[
        {
            'imageDigest': 'string',
            'imageTag': 'string'
        },
    ],
    nextToken='string',
    maxResults=123
)

Parameters

• registryId (string) -- The Amazon Web Services account ID that's associated with the public registry that contains the repository where images are described. If you do not specify a registry, the default public registry is assumed.
• repositoryName (string) --

  [REQUIRED]

  The repository that contains the images to describe.

• imageIds (list) --

  The list of image IDs for the requested repository.

  • (dict) --

    An object with identifying information for an Amazon ECR image.

    • imageDigest (string) --

      The sha256 digest of the image manifest.

    • imageTag (string) --

      The tag that's used for the image.

• nextToken (string) -- The nextToken value that's returned from a previous paginated DescribeImages request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. If there are no more results to return, this value is null . If you specify images with imageIds , you can't use this option.
• maxResults (integer) -- The maximum number of repository results that's returned by DescribeImages in paginated output. When this parameter is used, DescribeImages only returns maxResults results in a single page along with a nextToken response element. You can see the remaining results of the initial request by sending another DescribeImages request with the returned nextToken value. This value can be between 1 and 1000. If this parameter isn't used, then DescribeImages returns up to 100 results and a nextToken value, if applicable. If you specify images with imageIds , you can't use this option.

    • (dict) --

      An object that describes an image that's returned by a DescribeImages operation.

      • registryId (string) --

        The Amazon Web Services account ID that's associated with the public registry where this image belongs.

      • repositoryName (string) --

        The name of the repository where this image belongs.

      • imageDigest (string) --

        The sha256 digest of the image manifest.

      • imageTags (list) --

        The list of tags that's associated with this image.

        • (string) --

      • imageSizeInBytes (integer) --

        The size, in bytes, of the image in the repository.

        If the image is a manifest list, this is the max size of all manifests in the list.

The output of the docker images command shows the uncompressed image size, so it might return a larger image size than the image sizes that are returned by DescribeImages.

      • imagePushedAt (datetime) --

        The date and time, expressed in standard JavaScript date format, that the current image was pushed to the repository at.

      • imageManifestMediaType (string) --

        The media type of the image manifest.

      • artifactMediaType (string) --

        The artifact media type of the image.

  • nextToken (string) --

    The nextToken value to include in a future DescribeImages request. When the results of a DescribeImages request exceed maxResults , you can use this value to retrieve the next page of results. If there are no more results to return, this value is null .
