list-namespaces

Description

Lists summary information about the namespaces that were created by the current Amazon Web Services account.

See also: AWS API Documentation

list-namespaces 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: Namespaces

Options

--filters (list)

A complex type that contains specifications for the namespaces that you want to list.

If you specify more than one filter, a namespace must match all filters to be returned by ListNamespaces .

(structure)

A complex type that identifies the namespaces that you want to list. You can choose to list public or private namespaces.

Name -> (string)

Specify the namespaces that you want to get using one of the following.

  • TYPE : Gets the namespaces of the specified type.
  • NAME : Gets the namespaces with the specified name.
  • HTTP_NAME : Gets the namespaces with the specified HTTP name.

Values -> (list)

Specify the values that are applicable to the value that you specify for Name .

  • TYPE : Specify HTTP , DNS_PUBLIC , or DNS_PRIVATE .
  • NAME : Specify the name of the namespace, which is found in Namespace.Name .
  • HTTP_NAME : Specify the HTTP name of the namespace, which is found in Namespace.Properties.HttpProperties.HttpName .

(string)

Condition -> (string)

Specify the operator that you want to use to determine whether a namespace matches the specified value. Valid values for Condition are one of the following.

  • EQ : When you specify EQ for Condition , you can specify only one value. EQ is supported for TYPE , NAME , and HTTP_NAME . EQ is the default condition and can be omitted.
  • BEGINS_WITH : When you specify BEGINS_WITH for Condition , you can specify only one value. BEGINS_WITH is supported for TYPE , NAME , and HTTP_NAME .

Shorthand Syntax:

Name=string,Values=string,string,Condition=string ...

JSON Syntax:

[
  {
    "Name": "TYPE"|"NAME"|"HTTP_NAME",
    "Values": ["string", ...],
    "Condition": "EQ"|"IN"|"BETWEEN"|"BEGINS_WITH"
  }
  ...
]

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To list namespaces

The following list-namespaces example lists namespaces.

The ID of the namespace.

Arn -> (string)

The Amazon Resource Name (ARN) that Cloud Map assigns to the namespace when you create it.

The type of the namespace, either public or private.

Description -> (string)

A description for the namespace.

ServiceCount -> (integer)

The number of services that were created using the namespace.

Properties -> (structure)

The properties of the namespace.

DnsProperties -> (structure)

A complex type that contains the ID for the Route 53 hosted zone that Cloud Map creates when you create a namespace.

HostedZoneId -> (string)

The ID for the Route 53 hosted zone that Cloud Map creates when you create a namespace.

SOA -> (structure)

Start of Authority (SOA) record for the hosted zone.

TTL -> (long)

The time to live (TTL) for purposes of negative caching.

HttpProperties -> (structure)

A complex type that contains the name of an HTTP namespace.

HttpName -> (string)

The name of an HTTP namespace.

CreateDate -> (timestamp)

The date and time that the namespace was created.

NextToken -> (string)

If the response contains NextToken , submit another ListNamespaces request to get the next group of results. Specify the value of NextToken from the previous response in the next request.

Note

Cloud Map gets MaxResults namespaces and then filters them based on the specified criteria. It's possible that no namespaces in the first MaxResults namespaces matched the specified criteria but that subsequent groups of MaxResults namespaces do contain namespaces that match the criteria.
