API Reference (API Version 2015-09-21)

ListImages

Lists all the image IDs for a given repository.

You can filter images based on whether or not they are tagged by setting the tagStatus parameter to TAGGED or UNTAGGED. For example, you can filter your results to return only UNTAGGED images and then pipe that result to a BatchDeleteImage operation to delete them. Or, you can filter your results to return only TAGGED images to list all of the tags in your repository.

Request Syntax

Copy
{ "filter": { "tagStatus": "string" }, "maxResults": number, "nextToken": "string", "registryId": "string", "repositoryName": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

filter

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

Type: ListImagesFilter object

Required: No

maxResults

The maximum number of image results returned by ListImages in paginated output. When this parameter is used, ListImages 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 ListImages request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListImages returns up to 100 results and a nextToken value, if applicable.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 100.

Required: No

nextToken

The nextToken value returned from a previous paginated ListImages 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.

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.

Type: String

Required: No

registryId

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

Type: String

Pattern: [0-9]{12}

Required: No

repositoryName

The repository whose image IDs are to be listed.

Type: String

Length Constraints: Minimum length of 2. Maximum length of 256.

Pattern: (?:[a-z0-9]+(?:[._-][a-z0-9]+)*/)*[a-z0-9]+(?:[._-][a-z0-9]+)*

Required: Yes

Response Syntax

Copy
{ "imageIds": [ { "imageDigest": "string", "imageTag": "string" } ], "nextToken": "string" }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

imageIds

The list of image IDs for the requested repository.

Type: Array of ImageIdentifier objects

Array Members: Minimum number of 1 item. Maximum number of 100 items.

nextToken

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

Type: String

Errors

For information about the errors that are common to all actions, see Common Errors.

InvalidParameterException

The specified parameter is invalid. Review the available parameters for the API request.

HTTP Status Code: 400

RepositoryNotFoundException

The specified repository could not be found. Check the spelling of the specified repository and ensure that you are performing operations on the correct registry.

HTTP Status Code: 400

ServerException

These errors are usually caused by a server-side issue.

HTTP Status Code: 500

Example

In the following example or examples, the Authorization header contents (AUTHPARAMS) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

Example

This example lists all of the images in the amazonlinux repository.
