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.

ecrRepositoryPrefixes

The Amazon ECR repository prefixes associated with the pull through cache rules to return. If no repository prefix value is specified, all pull through cache rules are returned.

Type: Array of strings

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

Length Constraints: Minimum length of 2. Maximum length of 30.

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

Required: No

maxResults

The maximum number of pull through cache rules returned by DescribePullThroughCacheRulesRequest in paginated output. When this parameter is used, DescribePullThroughCacheRulesRequest 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 DescribePullThroughCacheRulesRequest request with the returned nextToken value. This value can be between 1 and 1000. If this parameter is not used, then DescribePullThroughCacheRulesRequest returns up to 100 results and a nextToken value, if applicable.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 1000.

Required: No

nextToken

The nextToken value returned from a previous paginated DescribePullThroughCacheRulesRequest 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.

Type: String

Required: No

registryId

The AWS account ID associated with the registry to return the pull through cache rules for. If you do not specify a registry, the default registry is assumed.

Type: String

Pattern: [0-9]{12}

Required: No
