create-activity

Description

Creates an activity. An activity is a task that you write in any programming language and host on any machine that has access to Step Functions. Activities must poll Step Functions using the GetActivityTask API action and respond using SendTask* API actions. This function lets Step Functions know the existence of your activity and returns an identifier for use in a state machine and when polling from the activity.

Note

This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.

Note

CreateActivity is an idempotent API. Subsequent requests won’t create a duplicate resource if it was already created. CreateActivity 's idempotency check is based on the activity name . If a following request has different tags values, Step Functions will ignore these differences and treat it as an idempotent request of the previous. In this case, tags will not be updated, even if they are different.

Options

--name (string)

The name of the activity to create. This name must be unique for your Amazon Web Services account and region for 90 days. For more information, see Limits Related to State Machine Executions in the Step Functions Developer Guide .

A name must not contain:

• white space
• brackets < > { } [ ]
• wildcard characters ? *
• special characters " # % \ ^ | ~ ` $ & , ; : /
• control characters (U+0000-001F , U+007F-009F )

To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.

--tags (list)

The list of tags to add to a resource.

An array of key-value pairs. For more information, see Using Cost Allocation Tags in the Amazon Web Services Billing and Cost Management User Guide , and Controlling Access Using IAM Tags .

Tags may only contain Unicode letters, digits, white space, or these symbols: _ . : / = + - @ .

(structure)

Tags are key-value pairs that can be associated with Step Functions state machines and activities.

An array of key-value pairs. For more information, see Using Cost Allocation Tags in the Amazon Web Services Billing and Cost Management User Guide , and Controlling Access Using IAM Tags .

Tags may only contain Unicode letters, digits, white space, or these symbols: _ . : / = + - @ .

key -> (string)

The key of a tag.

value -> (string)

The value of a tag.

Shorthand Syntax:

key=string,value=string ...

JSON Syntax:

[
  {
    "key": "string",
    "value": "string"
  }
  ...
]

--encryption-configuration (structure)

Settings to configure server-side encryption.

kmsKeyId -> (string)

An alias, alias ARN, key ID, or key ARN of a symmetric encryption KMS key to encrypt data. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

kmsDataKeyReusePeriodSeconds -> (integer)

Maximum duration that Step Functions will reuse data keys. When the period expires, Step Functions will call GenerateDataKey . Only applies to customer managed keys.

type -> (string)

Encryption type

Shorthand Syntax:

kmsKeyId=string,kmsDataKeyReusePeriodSeconds=integer,type=string

JSON Syntax:

{
  "kmsKeyId": "string",
  "kmsDataKeyReusePeriodSeconds": integer,
  "type": "AWS_OWNED_KEY"|"CUSTOMER_MANAGED_KMS_KEY"
}

--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. 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.

Output

activityArn -> (string)

The Amazon Resource Name (ARN) that identifies the created activity.

creationDate -> (timestamp)

The date the activity is created.
