The NodeGroupControllerService provides methods to manage node groups of Compute Engine managed instances. v1

Package

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of NodeGroupControllerClient.

Parameters
Name	Description
`opts`	`ClientOptions`
`gaxInstance`	`typeof gax \| typeof gax.fallback` : loaded instance of `google-gax`. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new NodeGroupControllerClient({fallback: 'rest'}, gax); ```

resizeNodeGroup(request, options)

resizeNodeGroup(request?: protos.google.cloud.dataproc.v1.IResizeNodeGroupRequest, options?: CallOptions): Promise<[
        LROperation<protos.google.cloud.dataproc.v1.INodeGroup, protos.google.cloud.dataproc.v1.INodeGroupOperationMetadata>,
        protos.google.longrunning.IOperation | undefined,
        {} | undefined
    ]>;

Resizes a node group in a cluster. The returned is [NodeGroupOperationMetadata](https://cloud.google.com/dataproc/docs/reference/rpc/google.cloud.dataproc.v1#nodegroupoperationmetadata).

Parameters
Name	Description
`request`	`protos.google.cloud.dataproc.v1.IResizeNodeGroupRequest` The request object that will be sent.
`options`	`CallOptions` Call options. See CallOptions for more details.

Returns
Type	Description
`Promise<[ LROperation<protos.google.cloud.dataproc.v1.INodeGroup, protos.google.cloud.dataproc.v1.INodeGroupOperationMetadata>, protos.google.longrunning.IOperation \| undefined, {} \| undefined ]>`	{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its `promise()` method returns a promise you can `await` for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.
