CreateDeployment

Creates a continuous deployment for a target, which is a Greengrass core device or group of core devices. When you add a new core device to a group of core devices that has a deployment, AWS IoT Greengrass deploys that group's deployment to the new device.

You can define one deployment for each target. When you create a new deployment for a target that has an existing deployment, you replace the previous deployment. AWS IoT Greengrass applies the new deployment to the target devices.

Every deployment has a revision number that indicates how many deployment revisions you define for a target. Use this operation to create a new revision of an existing deployment.

For more information, see the Create deployments in the AWS IoT Greengrass V2 Developer Guide.

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

clientToken

A unique, case-sensitive identifier that you can provide to ensure that the request is idempotent. Idempotency means that the request is successfully processed only once, even if you send the request multiple times. When a request succeeds, and you specify the same client token for subsequent successful requests, the AWS IoT Greengrass V2 service returns the successful response that it caches from the previous request. AWS IoT Greengrass V2 caches successful responses for idempotent requests for up to 8 hours.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[a-zA-Z0-9-]+$

Required: No

components

The components to deploy. This is a dictionary, where each key is the name of a component, and each key's value is the version and configuration to deploy for that component.

Type: String to ComponentDeploymentSpecification object map

Key Length Constraints: Minimum length of 1.

Required: No

deploymentName

The name of the deployment.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Required: No

deploymentPolicies

The deployment policies for the deployment. These policies define how the deployment updates components and handles failure.

Type: DeploymentPolicies object

Required: No

iotJobConfiguration

The job configuration for the deployment configuration. The job configuration specifies the rollout, timeout, and stop configurations for the deployment configuration.

Type: DeploymentIoTJobConfiguration object

Required: No

parentTargetArn

The parent deployment's target ARN within a subdeployment.

Type: String

Pattern: arn:[^:]*:iot:[^:]*:[0-9]+:thinggroup/.+

Required: No

tags

A list of key-value pairs that contain metadata for the resource. For more information, see Tag your resources in the AWS IoT Greengrass V2 Developer Guide.

Type: String to string map

Map Entries: Maximum number of 200 items.

Key Length Constraints: Minimum length of 1. Maximum length of 128.

Value Length Constraints: Maximum length of 256.

Required: No

targetArn

The ARN of the target AWS IoT thing or thing group. When creating a subdeployment, the targetARN can only be a thing group.

Type: String

Pattern: arn:[^:]*:iot:[^:]*:[0-9]+:(thing|thinggroup)/.+

Required: Yes
