aws sns create-topic
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 https://aws.amazon.com/sns. 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 | Description |
|---|---|
--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. The following attribute applies only to server-side-encryption: KmsMasterKeyId – The ID of an AWS-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 AWS Key Management Service API Reference. The following attributes apply only to FIFO topics: FifoTopic – When this is set to true, a FIFO topic is created. 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 the MessageDeduplicationId parameter for the Publish action |
--tags <list> | The list of tags to add to a new topic. To be able to tag a topic on creation, you must have the sns:CreateTopic and sns:TagResource permissions |
--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 |
