describe_repositories#

ECR.Client.describe_repositories(**kwargs)#

Describes image repositories in a registry.

See also: AWS API Documentation

Request Syntax

response = client.describe_repositories(
    registryId='string',
    repositoryNames=[
        'string',
    ],
    nextToken='string',
    maxResults=123
)
Parameters:

  • registryId (string) – The Amazon Web Services account ID associated with the registry that contains the repositories to be described. If you do not specify a registry, the default registry is assumed.

  • repositoryNames (list) –

    A list of repositories to describe. If this parameter is omitted, then all repositories in a registry are described.

    • (string) –

  • nextToken (string) –

    The nextToken value returned from a previous paginated DescribeRepositories 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. This value is null when there are no more results to return. This option cannot be used when you specify repositories with repositoryNames.

    Note

    This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

  • maxResults (integer) – The maximum number of repository results returned by DescribeRepositories in paginated output. When this parameter is used, DescribeRepositories only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeRepositories request with the returned nextToken value. This value can be between 1 and 1000. If this parameter is not used, then DescribeRepositories returns up to 100 results and a nextToken value, if applicable. This option cannot be used when you specify repositories with repositoryNames.

Response Structure

  • (dict) –

    • repositories (list) –

      A list of repository objects corresponding to valid repositories.

      • (dict) –

        An object representing a repository.

        • repositoryArn (string) –

          The Amazon Resource Name (ARN) that identifies the repository. The ARN contains the arn:aws:ecr namespace, followed by the region of the repository, Amazon Web Services account ID of the repository owner, repository namespace, and repository name. For example, arn:aws:ecr:region:012345678910:repository-namespace/repository-name.

        • registryId (string) –

          The Amazon Web Services account ID associated with the registry that contains the repository.

        • repositoryName (string) –

          The name of the repository.

        • repositoryUri (string) –

          The URI for the repository. You can use this URI for container image push and pull operations.

        • createdAt (datetime) –

          The date and time, in JavaScript date format, when the repository was created.

        • imageTagMutability (string) –

          The tag mutability setting for the repository.

        • imageScanningConfiguration (dict) –

          The image scanning configuration for a repository.

          • scanOnPush (boolean) –

            The setting that determines whether images are scanned after being pushed to a repository. If set to true, images will be scanned after being pushed. If this parameter is not specified, it will default to false and images will not be scanned unless a scan is manually started with the API_StartImageScan API.

        • encryptionConfiguration (dict) –

          The encryption configuration for the repository. This determines how the contents of your repository are encrypted at rest.

          • encryptionType (string) –

            The encryption type to use.

            If you use the KMS encryption type, the contents of the repository will be encrypted using server-side encryption with Key Management Service key stored in KMS. When you use KMS to encrypt your data, you can either use the default Amazon Web Services managed KMS key for Amazon ECR, or specify your own KMS key, which you already created.

            If you use the KMS_DSSE encryption type, the contents of the repository will be encrypted with two layers of encryption using server-side encryption with the KMS Management Service key stored in KMS. Similar to the KMS encryption type, you can either use the default Amazon Web Services managed KMS key for Amazon ECR, or specify your own KMS key, which you’ve already created.

            If you use the AES256 encryption type, Amazon ECR uses server-side encryption with Amazon S3-managed encryption keys which encrypts the images in the repository using an AES256 encryption algorithm.

            For more information, see Amazon ECR encryption at rest in the Amazon Elastic Container Registry User Guide.

          • kmsKey (string) –

            If you use the KMS encryption type, specify the KMS key to use for encryption. The alias, key ID, or full ARN of the KMS key can be specified. The key must exist in the same Region as the repository. If no key is specified, the default Amazon Web Services managed KMS key for Amazon ECR will be used.

    • nextToken (string) –

      The nextToken value to include in a future DescribeRepositories request. When the results of a DescribeRepositories 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.

Exceptions

  • ECR.Client.exceptions.ServerException

  • ECR.Client.exceptions.InvalidParameterException

  • ECR.Client.exceptions.RepositoryNotFoundException

Examples

The following example obtains a list and description of all repositories in the default registry to which the current user has access.

response = client.describe_repositories(
)

print(response)
