Defined in:: (unknown)

Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

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.

Sending a Request Using GreengrassV2

var greengrassv2 = new AWS.GreengrassV2();
greengrassv2.batchAssociateClientDeviceWithCoreDevice(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the GreengrassV2 object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var greengrassv2 = new AWS.GreengrassV2({apiVersion: '2020-11-30'});

You can also set the API version globally in AWS.config.apiVersions using the greengrassv2 service identifier:

AWS.config.apiVersions = {
  greengrassv2: '2020-11-30',
  // other service API versions
};

var greengrassv2 = new AWS.GreengrassV2();

Method Details

batchAssociateClientDeviceWithCoreDevice(params = {}, callback) ⇒ `AWS.Request`

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.

Note: 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(params = {}, callback) ⇒ `AWS.Request`

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.

Note: IoT Greengrass currently supports Lambda functions on only Linux core devices.

    - pinned — (Boolean)
      Whether or not the Lambda function is pinned, or long-lived.
      
      A pinned Lambda function starts when IoT Greengrass starts and keeps running in its own container.
      
      A non-pinned Lambda function starts only when it receives a work item and exists after it idles for maxIdleTimeInSeconds. If the function has multiple work items, the IoT Greengrass Core software creates multiple instances of the function.
      
      Default: true
    - inputPayloadEncodingType — (String)
      The encoding type that the Lambda function supports.

Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.
Context (this):
- (AWS.Response) —
  the response object containing error, data properties, and the original request object.
Parameters:
- err (Error) —
  the error object returned from the request. Set to null if the request is successful.
- data (Object) —
  the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:
  - arn — (String)
    The ARN of the component version.
  - componentName — (String)
    The name of the component.
  - componentVersion — (String)
    The version of the component.
  - creationTimestamp — (Date)
    The time at which the component was created, expressed in ISO 8601 format.

    A message that communicates details, such as errors, about the status of the component.
    
    errors — (map<String>)
    A dictionary of errors that communicate why the component is in an error state. For example, if IoT Greengrass can't access an artifact for the component, then errors contains the artifact's URI as a key, and the error message as the value for that key.

Returns:

(AWS.Request) —
a handle to the operation request for subsequent event callback registration.

createDeployment(params = {}, callback) ⇒ `AWS.Request`

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.

- targetArn — (String)
  The ARN of the target IoT thing or thing group.
- deploymentName — (String)
  The name of the deployment.
- components — (map<map>)
  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.
  - componentVersion — (String)
    The version of the component.
  - configurationUpdate — (map)
    The configuration updates to deploy for the component. You can define reset updates and merge updates. A reset updates the keys that you specify to the default configuration for the component. A merge updates the core device's component configuration with the keys and values that you specify. The IoT Greengrass Core software applies reset updates before it applies merge updates. For more information, see Update component configurations in the IoT Greengrass V2 Developer Guide.
    - merge — (String)
      A serialized JSON string that contains the configuration object to merge to target devices. The core device merges this configuration with the component's existing configuration. If this is the first time a component deploys on a device, the core device merges this configuration with the component's default configuration. This means that the core device keeps it's existing configuration for keys and values that you don't specify in this object. For more information, see Merge configuration updates in the IoT Greengrass V2 Developer Guide.
    - reset — (Array<String>)
      The list of configuration nodes to reset to default values on target devices. Use JSON pointers to specify each node to reset. JSON pointers start with a forward slash (/) and use forward slashes to separate the key for each level in the object. For more information, see the JSON pointer specification and Reset configuration updates in the IoT Greengrass V2 Developer Guide.
  - runWith — (map)
    The system user and group that the IoT Greengrass Core software uses to run component processes on the core device. If you omit this parameter, the IoT Greengrass Core software uses the system user and group that you configure for the core device. For more information, see Configure the user and group that run components in the IoT Greengrass V2 Developer Guide.
    - posixUser — (String)
      The POSIX system user and, optionally, group to use to run this component on Linux core devices. The user, and group if specified, must exist on each Linux core device. Specify the user and group separated by a colon (:) in the following format: user:group. The group is optional. If you don't specify a group, the IoT Greengrass Core software uses the primary user for the group.
      
      If you omit this parameter, the IoT Greengrass Core software uses the default system user and group that you configure on the Greengrass nucleus component. For more information, see Configure the user and group that run components.
    - systemResourceLimits — (map)
      The system resource limits to apply to this component's process on the core device. IoT Greengrass currently supports this feature on only Linux core devices.
      
      If you omit this parameter, the IoT Greengrass Core software uses the default system resource limits that you configure on the Greengrass nucleus component. For more information, see Configure system resource limits for components.
      
      memory — (Integer)
      The maximum amount of RAM, expressed in kilobytes, that a component's processes can use on the core device.
      
      cpus — (Float)
      The maximum amount of CPU time that a component's processes can use on the core device. A core device's total CPU time is equivalent to the device's number of CPU cores. For example, on a core device with 4 CPU cores, you can set this value to 2 to limit the component's processes to 50 percent usage of each CPU core. On a device with 1 CPU core, you can set this value to 0.25 to limit the component's processes to 25 percent usage of the CPU. If you set this value to a number greater than the number of CPU cores, the IoT Greengrass Core software doesn't limit the component's CPU usage.
    - windowsUser — (String)
      The Windows user to use to run this component on Windows core devices. The user must exist on each Windows core device, and its name and password must be in the LocalSystem account's Credentials Manager instance.
      
      If you omit this parameter, the IoT Greengrass Core software uses the default Windows user that you configure on the Greengrass nucleus component. For more information, see Configure the user and group that run components.

JSON pointers start with a forward slash (/) and use forward slashes to separate the key for each level in the object. For more information, see the JSON pointer specification and Reset configuration updates in the IoT Greengrass V2 Developer Guide.
    
    runWith — (map)
    The system user and group that the IoT Greengrass Core software uses to run component processes on the core device.

On a device with 1 CPU core, you can set this value to 0.25 to limit the component's processes to 25 percent usage of the CPU. If you set this value to a number greater than the number of CPU cores, the IoT Greengrass Core software doesn't limit the component's CPU usage.
    
    windowsUser — (String)
    The Windows user to use to run this component on Windows core devices. The user must exist on each Windows core device, and its name and password must be in the LocalSystem account's Credentials Manager instance.

resolveComponentCandidates(params = {}, callback) ⇒ `AWS.Request`

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.

Service Reference:

ResolveComponentCandidates

Examples:

Calling the resolveComponentCandidates operation

var params = {
  componentCandidates: [ /* required */
