AutoscalingPolicyServiceClient

AutoscalingPolicyServiceClient

The API interface for managing autoscaling policies in the Cloud Dataproc API.

Constructor

new AutoscalingPolicyServiceClient(optionsopt)

Construct an instance of AutoscalingPolicyServiceClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description
client_email string <optional>
private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.

keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.

port number <optional>

The port on which to connect to the remote host.

projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.

apiEndpoint string <optional>

The domain name of the API remote host.

clientConfig gax.ClientConfig <optional>

Client configuration override. Follows the structure of gapicConfig.

fallback boolean <optional>

Use HTTP fallback mode. In fallback mode, a special browser-compatible transport implementation is used instead of gRPC transport. In browser context (if the window object is defined) the fallback mode is enabled automatically; set options.fallback to false if you need to override this behavior.

Members

scopes

The scopes needed to make gRPC calls for every method defined in this service.

getProjectId() → {Promise}

Return the project ID used by this class.

Returns:
Type Description
Promise

A promise that resolves to string containing the project ID.

initialize() → {Promise}

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns:
Type Description
Promise

A promise that resolves to an authenticated service stub.

listAutoscalingPolicies(request, optionsopt) → {Promise}

Lists autoscaling policies in the project.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
parent string

Required. The "resource name" of the region or location, as described in https://cloud.google.com/apis/design/resource_names.

  • For projects.regions.autoscalingPolicies.list, the resource name of the region has the following format: projects/{project_id}/regions/{region}

  • For projects.locations.autoscalingPolicies.list, the resource name of the location has the following format: projects/{project_id}/locations/{location}

pageSize number <optional>

Optional. The maximum number of results to return in each response. Must be less than or equal to 1000. Defaults to 100.

pageToken string <optional>

Optional. The page token, returned by a previous call, to request the next page of results.

options object <optional>

Call options. See CallOptions for more details.

Returns:
Type Description
Promise
  • The promise which resolves to an array. The first element of the array is Array of AutoscalingPolicy. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using listAutoscalingPoliciesAsync() method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.

listAutoscalingPoliciesAsync(request, optionsopt) → {Object}

Equivalent to listAutoscalingPolicies, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
parent string

Required. The "resource name" of the region or location, as described in https://cloud.google.com/apis/design/resource_names.

  • For projects.regions.autoscalingPolicies.list, the resource name of the region has the following format: projects/{project_id}/regions/{region}

  • For projects.locations.autoscalingPolicies.list, the resource name of the location has the following format: projects/{project_id}/locations/{location}

pageSize number <optional>

Optional. The maximum number of results to return in each response. Must be less than or equal to 1000. Defaults to 100.

pageToken string <optional>

Optional. The page token, returned by a previous call, to request the next page of results.

options object <optional>

Call options. See CallOptions for more details.

Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing AutoscalingPolicy. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.

Example
const iterable = client.listAutoscalingPoliciesAsync(request);
for await (const response of iterable) {
  // process response
}

listAutoscalingPoliciesStream(request, optionsopt) → {Stream}

Equivalent to method.name.toCamelCase(), but returns a NodeJS Stream object.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
parent string

Required. The "resource name" of the region or location, as described in https://cloud.google.com/apis/design/resource_names.

  • For projects.locations.autoscalingPolicies.list, the resource name of the location has the following format: projects/{project_id}/locations/{location}

pageSize number <optional>

Optional. The maximum number of results to return in each response. Must be less than or equal to 1000. Defaults to 100.

Please see the documentation for more details and examples.
