See 'aws help' for descriptions of global parameters.


[--registry-id <value>]
--repository-name <value>
[--image-ids <value>]
[--next-token <value>]
[--max-results <value>]
[--filter <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--registry-id (string)

The AWS account ID associated with the registry that contains the repository. If you do not specify a registry, the default registry is assumed.

--repository-name (string)

The name of the repository.

--image-ids (list)

The list of imageIDs to be included.

Shorthand Syntax:

imageDigest=string,imageTag=string ...

JSON Syntax:

    "imageDigest": "string",
    "imageTag": "string"

--next-token (string)

The nextToken value returned from a previous paginated GetLifecyclePolicyPreviewRequest request where maxResults was used and theresults exceeded the value of that parameter. Pagination continues from the end of theprevious 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 images with imageIds .

--max-results (integer)

The maximum number of repository results returned by GetLifecyclePolicyPreviewRequest inpaginated output. When this parameter is used, GetLifecyclePolicyPreviewRequest 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 sendinganother GetLifecyclePolicyPreviewRequest request with the returned nextToken value. This value can be between 1 and 1000. If thisparameter is not used, then GetLifecyclePolicyPreviewRequest returns up to100 results and a nextToken value, ifapplicable. This option cannot be used when you specify images with imageIds .

--filter (structure)

An optional parameter that filters results based on image tag status and all tags, if tagged.

Shorthand Syntax:


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.

--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.

See 'aws help' for descriptions of global parameters.
