Creates an HTTP namespace. Service instances registered using an HTTP namespace can be discovered using a DiscoverInstances request but can't be discovered using DNS.

For the current quota on the number of namespaces that you can create using the same Amazon Web Services account, see Cloud Map quotas in the Cloud Map Developer Guide .

Request Syntax

response = client.create_http_namespace(
            'Key': 'string',
            'Value': 'string'
  • Name (string) --


    The name that you want to assign to this namespace.

  • CreatorRequestId (string) --

    A unique string that identifies the request and that allows failed CreateHttpNamespace requests to be retried without the risk of running the operation twice. CreatorRequestId can be any unique string (for example, a date/time stamp).

    This field is autopopulated if not provided.

  • Description (string) -- A description for the namespace.
  • Tags (list) --

    The tags to add to the namespace. Each tag consists of a key and an optional value that you define. Tags keys can be up to 128 characters in length, and tag values can be up to 256 characters in length.

    • (dict) --

      A custom key-value pair that's associated with a resource.

      • Key (string) -- [REQUIRED]

        The key identifier, or name, of the tag.

      • Value (string) -- [REQUIRED]

        The string value that's associated with the key of the tag. You can set the value of a tag to an empty string, but you can't set the value of a tag to null.

Return type



Response Syntax

    'OperationId': 'string'

Response Structure

  • (dict) --

    • OperationId (string) --

      A value that you can use to determine whether the request completed successfully. To get the status of the operation, see GetOperation.


  • ServiceDiscovery.Client.exceptions.InvalidInput
  • ServiceDiscovery.Client.exceptions.NamespaceAlreadyExists
  • ServiceDiscovery.Client.exceptions.ResourceLimitExceeded
  • ServiceDiscovery.Client.exceptions.DuplicateRequest
  • ServiceDiscovery.Client.exceptions.TooManyTagsException


This example creates an HTTP namespace.

response = client.create_http_namespace(
    Description=' AWS Cloud Map HTTP Namespace',


Expected Output:

    'OperationId': 'httpvoqozuhfet5kzxoxg-a-response-example',
    'ResponseMetadata': {
        '...': '...',
