describe-images

Description

Returns metadata about the images in a repository.

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, so it may return a larger image size than the image sizes returned by DescribeImages .

See also: AWS API Documentation

describe-images is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: imageDetails

Options

--registry-id (string)

The Amazon Web Services account ID associated with the registry that contains the repository in which to describe images. If you do not specify a registry, the default registry is assumed.

--repository-name (string)

The repository that contains the images to describe.

--image-ids (list)

The list of image IDs for the requested repository.

(structure)

An object with identifying information for an image in an Amazon ECR repository.

imageDigest -> (string)

The sha256 digest of the image manifest.

imageTag -> (string)

The tag used for the image.

Shorthand Syntax:

imageDigest=string,imageTag=string ...

JSON Syntax:

[
  {
    "imageDigest": "string",
    "imageTag": "string"
  }
  ...
]

--filter (structure)

The filter key and value with which to filter your DescribeImages results.

tagStatus -> (string)

The tag status with which to filter your DescribeImages results. You can filter results based on whether they are TAGGED or UNTAGGED .

Shorthand Syntax:

tagStatus=string

JSON Syntax:

{
  "tagStatus": "TAGGED"|"UNTAGGED"|"ANY"
}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

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 describe an image in a repository

The folowing describe-images example displays details about an image in the cluster-autoscaler repository with the tag v1.13.6.

aws ecr describe-images \
    --repository-name cluster-autoscaler \
    --image-ids imageTag=v1.13.6

Output:

{
    "imageDetails": [
        {
            "registryId": "012345678910",
            "repositoryName": "cluster-autoscaler",
            "imageDigest": "sha256:4a1c6567c38904384ebc64e35b7eeddd8451110c299e3368d2210066487d97e5",
            "imageTags": [
                "v1.13.6"
            ],
            "imageSizeInBytes": 48318255,
            "imagePushedAt": 1565128275.0
        }
    ]
}

Output

imageDetails -> (list)

A list of ImageDetail objects that contain data about the image.

(structure)

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

registryId -> (string)

The Amazon Web Services account ID associated with the registry to which this image belongs.

repositoryName -> (string)

The name of the repository to which this image belongs.

imageDigest -> (string)

The sha256 digest of the image manifest.

imageTags -> (list)

The list of tags associated with this image.

(string)

imageSizeInBytes -> (long)

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

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

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, so it may return a larger image size than the image sizes returned by DescribeImages .

imagePushedAt -> (timestamp)

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

imageScanStatus -> (structure)

The current state of the scan.

status -> (string)

The current state of an image scan.

description -> (string)

The description of the image scan status.

imageScanFindingsSummary -> (structure)

A summary of the last completed image scan.

imageScanCompletedAt -> (timestamp)

The time of the last completed image scan.

vulnerabilitySourceUpdatedAt -> (timestamp)

The time when the vulnerability data was last scanned.

findingSeverityCounts -> (map)

The image vulnerability counts, sorted by severity.

key -> (string)

value -> (integer)

imageManifestMediaType -> (string)

The media type of the image manifest.

artifactMediaType -> (string)

The artifact media type of the image.

lastRecordedPullTime -> (timestamp)

The date and time, expressed in standard JavaScript date format, when Amazon ECR recorded the last image pull.

Note

Amazon ECR refreshes the last image pull timestamp at least once every 24 hours. For example, if you pull an image once a day then the lastRecordedPullTime timestamp will indicate the exact time that the image was last pulled. However, if you pull an image once an hour, because Amazon ECR refreshes the lastRecordedPullTime timestamp at least once every 24 hours, the result may not be the exact time that the image was last pulled.

nextToken -> (string)

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