Interface for accessing AWS GreengrassV2.

Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAWSGreengrassV2 instead.

IoT Greengrass brings local compute, messaging, data management, sync, and ML inference capabilities to edge devices. This enables devices to collect and analyze data closer to the source of information, react autonomously to local events, and communicate securely with each other on local networks. Local devices can also communicate securely with Amazon Web Services IoT Core and export IoT data to the Amazon Web Services Cloud. IoT Greengrass developers can use Lambda functions and components to create and deploy applications to fleets of edge devices for local operation.

IoT Greengrass Version 2 provides a new major version of the IoT Greengrass Core software, new APIs, and a new console. Use this API reference to learn how to use the IoT Greengrass V2 API operations to manage components, manage deployments, and core devices.

For more information, see What is IoT Greengrass? in the IoT Greengrass V2 Developer Guide.

Method Detail

batchAssociateClientDeviceWithCoreDevice

BatchAssociateClientDeviceWithCoreDeviceResult batchAssociateClientDeviceWithCoreDevice(BatchAssociateClientDeviceWithCoreDeviceRequest batchAssociateClientDeviceWithCoreDeviceRequest)

Associate a list of client devices with a core device. Use this API operation to specify which client devices can discover a core device through cloud discovery. With cloud discovery, client devices connect to IoT Greengrass to retrieve associated core devices' connectivity information and certificates. For more information, see Configure cloud discovery in the IoT Greengrass V2 Developer Guide.

Client devices are local IoT devices that connect to and communicate with an IoT Greengrass core device over MQTT. You can connect client devices to a core device to sync MQTT messages and data to Amazon Web Services IoT Core and interact with client devices in Greengrass components. For more information, see Interact with local IoT devices in the IoT Greengrass V2 Developer Guide.

createComponentVersion

CreateComponentVersionResult createComponentVersion(CreateComponentVersionRequest createComponentVersionRequest)

Creates a component. Components are software that run on Greengrass core devices. After you develop and test a component on your core device, you can use this operation to upload your component to IoT Greengrass. Then, you can deploy the component to other core devices.

You can use this operation to do the following:

• Create components from recipes

  Create a component from a recipe, which is a file that defines the component's metadata, parameters, dependencies, lifecycle, artifacts, and platform capability. For more information, see IoT Greengrass component recipe reference in the IoT Greengrass V2 Developer Guide.

  To create a component from a recipe, specify inlineRecipe when you call this operation.

• Create components from Lambda functions

  Create a component from an Lambda function that runs on IoT Greengrass. This creates a recipe and artifacts from the Lambda function's deployment package. You can use this operation to migrate Lambda functions from IoT Greengrass V1 to IoT Greengrass V2.

  This function only accepts Lambda functions that use the following runtimes:

  • Python 2.7 – python2.7

  • Python 3.7 – python3.7

  • Python 3.8 – python3.8

  • Java 8 – java8

  • Node.js 10 – nodejs10.x

  • Node.js 12 – nodejs12.x

  To create a component from a Lambda function, specify lambdaFunction when you call this operation.

Returns:

Result of the CreateComponentVersion operation returned by the service.

Throws:

ValidationException - The request isn't valid. This can occur if your request contains malformed JSON or unsupported characters.

ConflictException - Your request has conflicting operations. This can occur if you're trying to perform more than one operation on the same resource at the same time.

ThrottlingException - Your request exceeded a request rate quota. For example, you might have exceeded the amount of times that you can retrieve device or deployment status per second.

InternalServerException - IoT Greengrass can't process your request right now. Try again later.

RequestAlreadyInProgressException - The request is already in progress. This exception occurs when you use a client token for multiple requests while IoT Greengrass is still processing an earlier request that uses the same client token.

AWS API Documentation

createDeployment

CreateDeploymentResult createDeployment(CreateDeploymentRequest createDeploymentRequest)

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, 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. 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. This operation returns the revision number of the new deployment when you create it.

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

Parameters:

createDeploymentRequest -

Returns:

Result of the CreateDeployment operation returned by the service.

Throws:

resolveComponentCandidates

ResolveComponentCandidatesResult resolveComponentCandidates(ResolveComponentCandidatesRequest resolveComponentCandidatesRequest)

Retrieves a list of components that meet the component, version, and platform requirements of a deployment. Greengrass core devices call this operation when they receive a deployment to identify the components to install.

This operation identifies components that meet all dependency requirements for a deployment. If the requirements conflict, then this operation returns an error and the deployment fails. For example, this occurs if component A requires version >2.0.0 and component B requires version <2.0.0 of a component dependency.

When you specify the component candidates to resolve, IoT Greengrass compares each component's digest from the core device with the component's digest in the Amazon Web Services Cloud. If the digests don't match, then IoT Greengrass specifies to use the version from the Amazon Web Services Cloud.

To use this operation, you must use the data plane API endpoint and authenticate with an IoT device certificate. For more information, see IoT Greengrass endpoints and quotas.

Parameters:

resolveComponentCandidatesRequest -

Returns:

Result of the ResolveComponentCandidates operation returned by the service.

Throws:

ValidationException - The request isn't valid. This can occur if your request contains malformed JSON or unsupported characters.

AccessDeniedException - You don't have permission to perform the action.

shutdown

void shutdown()

Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:

request - The originally executed request.

Returns:

The response metadata for the specified request, or null if none is available.
