create-topic

Description

Creates a topic to which notifications can be published. Users can create at most 100,000 standard topics (at most 1,000 FIFO topics). For more information, see Creating an Amazon SNS topic in the Amazon SNS Developer Guide . This action is idempotent, so if the requester already owns a topic with the specified name, that topic's ARN is returned without creating a new topic.

Options

--name (string)

The name of the topic you want to create.

Constraints: Topic names must be made up of only uppercase and lowercase ASCII letters, numbers, underscores, and hyphens, and must be between 1 and 256 characters long.

For a FIFO (first-in-first-out) topic, the name must end with the .fifo suffix.

--attributes (map)

A map of attributes with their corresponding values.

The following lists the names, descriptions, and values of the special request parameters that the CreateTopic action uses:

  • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
  • DisplayName – The display name to use for a topic with SMS subscriptions.
  • FifoTopic – Set to true to create a FIFO topic.
  • Policy – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.
  • SignatureVersion – The signature version corresponds to the hashing algorithm used while creating the signature of the notifications, subscription confirmations, or unsubscribe confirmation messages sent by Amazon SNS. By default, SignatureVersion is set to 1 .
  • TracingConfig – Tracing mode of an Amazon SNS topic. By default TracingConfig is set to PassThrough , and the topic passes through the tracing header it receives from an Amazon SNS publisher to its subscriptions. If set to Active , Amazon SNS will vend X-Ray segment data to topic owner account if the sampled flag in the tracing header is true. This is only supported on standard topics.

The following attribute applies only to server-side encryption :

  • KmsMasterKeyId – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms . For more examples, see KeyId in the Key Management Service API Reference .

The following attributes apply only to FIFO topics :

  • ArchivePolicy – Adds or updates an inline policy document to archive messages stored in the specified Amazon SNS topic.
  • BeginningArchiveTime – The earliest starting point at which a message in the topic’s archive can be replayed from. This point in time is based on the configured message retention period set by the topic’s message archiving policy.
  • ContentBasedDeduplication – Enables content-based deduplication for FIFO topics.
    • By default, ContentBasedDeduplication is set to false . If you create a FIFO topic and this attribute is false , you must specify a value for the MessageDeduplicationId parameter for the Publish action.
    • When you set ContentBasedDeduplication to true , Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message). (Optional) To override the generated value, you can specify a value for the MessageDeduplicationId parameter for the Publish action.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--tags (list)

The list of tags to add to a new topic.

Note

To be able to tag a topic on creation, you must have the sns:CreateTopic and sns:TagResource permissions.

(structure)

The list of tags to be added to the specified topic.

Key -> (string)

The required key portion of the tag.

Value -> (string)

The optional value portion of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--data-protection-policy (string)

The body of the policy document you want to use for this topic.

You can only add one policy per topic.

The policy must be in JSON string format.

Length Constraints: Maximum length of 30,720.

--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.

--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.

--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 create an SNS topic

The following create-topic example creates an SNS topic named my-topic.

aws sns create-topic \
    --name my-topic

Output:

{
    "ResponseMetadata": {
        "RequestId": "1469e8d7-1642-564e-b85d-a19b4b341f83"
    },
    "TopicArn": "arn:aws:sns:us-west-2:123456789012:my-topic"
}

For more information, see Using the AWS Command Line Interface with Amazon SQS and Amazon SNS in the AWS Command Line Interface User Guide.

Output

TopicArn -> (string)

The Amazon Resource Name (ARN) assigned to the created topic.
