[ aws . ecr-public ]



Returns details for a public registry.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

describe-registries 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: registries


[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]


--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.

See 'aws help' for descriptions of global parameters.


registries -> (list)

An object containing the details for a public registry.


The details of a public registry.

registryId -> (string)

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

registryArn -> (string)

The Amazon Resource Name (ARN) of the public registry.

registryUri -> (string)

The URI of a public registry. The URI contains a universal prefix and the registry alias.

verified -> (boolean)

Whether the account is verified. This indicates whether the account is an AWS Marketplace vendor. If an account is verified, each public repository will received a verified account badge on the Amazon ECR Public Gallery.

aliases -> (list)

An array of objects representing the aliases for a public registry.


An object representing the aliases for a public registry. A public registry is given an alias upon creation but a custom alias can be set using the Amazon ECR console. For more information, see Registries in the Amazon Elastic Container Registry User Guide .

name -> (string)

The name of the registry alias.

status -> (string)

The status of the registry alias.

primaryRegistryAlias -> (boolean)

Whether or not the registry alias is the primary alias for the registry. If true, the alias is the primary registry alias and is displayed in both the repository URL and the image URI used in the docker pull commands on the Amazon ECR Public Gallery.


A registry alias that is not the primary registry alias can be used in the repository URI in a docker pull command.

defaultRegistryAlias -> (boolean)

Whether or not the registry alias is the default alias for the registry. When the first public repository is created, your public registry is assigned a default registry alias.

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.
