GkeHubClient

The GKE Hub service handles the registration of many Kubernetes clusters to Google Cloud, and the management of multi-cluster features over those clusters.

The GKE Hub service operates on the following resources:

Membership
Feature

GKE Hub is currently only available in the global region.

Membership management may be non-trivial: it is recommended to use one of the Google-provided client libraries or tools where possible when working with Membership resources.

Constructor

new GkeHubClient(optionsopt, gaxInstanceopt)

Construct an instance of GkeHubClient.

Parameters:

Name Type Attributes Description

options

object

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

Credentials object.

Properties

Name	Type	Attributes	Description
`client_email`	string	<optional>
`private_key`	string	<optional>

email

string

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

keyFilename

string

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

The port on which to connect to the remote host.

projectId

string

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

The domain name of the API remote host.

clientConfig

gax.ClientConfig

Client configuration override. Follows the structure of gapicConfig.

fallback

boolean

Use HTTP/1.1 REST mode. For more information, please check the documentation.

gaxInstance

gax

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 GkeHubClient({fallback: true}, gax);

Members

apiEndpoint

The DNS address for this API service.

apiEndpoint

The DNS address for this API service - same as servicePath.

port

The port for this API service.

scopes

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

servicePath

The DNS address for this API service.

Methods

(async) checkCreateFeatureProgress(name) → {Promise}

Check the status of the long running operation returned by createFeature().

Parameters:

Name	Type	Description
`name`	String	The operation name that will be passed.

Returns:

Type	Description
Promise	The promise which resolves to an object. The decoded operation object has result and metadata field to get information from. Please see the documentation for more details and examples.

close() → {Promise}

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns:

Type	Description
Promise	A promise that resolves when the client is closed.

featurePath(project, location, feature) → {string}

Return a fully-qualified feature resource name string.

Parameters:

Name	Type	Description
`project`	string
`location`	string
`feature`	string

Returns:

Type	Description
string	Resource name string.

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.

listFeaturesAsync(request, optionsopt) → {Object}

Equivalent to listFeatures, 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	Description
`parent`	string	The parent (project and location) where the Features will be listed. Specified in the format `projects/* /locations/*`.
`pageSize`	number	When requesting a 'page' of resources, `page_size` specifies number of resources to return. If unspecified or set to 0, all resources will be returned.
`pageToken`	string	Token returned by previous call to `ListFeatures` which specifies the position in the list from where to continue listing the resources.
`filter`	string	Lists Features that match the filter expression, following the syntax outlined in https://google.aip.dev/160. Examples: - Feature with the name "servicemesh" in project "foo-proj": name = "projects/foo-proj/locations/global/features/servicemesh" - Features that have a label called `foo`: labels.foo:* - Features that have a label called `foo` whose value is `bar`: labels.foo = bar
`orderBy`	string	One or more fields to compare and use to sort the output. See https://google.aip.dev/132#ordering.

options

object

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 Feature. 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.

listFeaturesStream(request, optionsopt) → {Stream}

Parameters:

Name Type Attributes Description

request

Object

The request object that will be sent.

Properties

Name	Type	Description
`parent`	string	The parent (project and location) where the Features will be listed. Specified in the format `projects/* /locations/*`.

object

Call options. See CallOptions for more details.

Returns:

Type	Description
Stream	An object stream which emits an object representing Feature on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using `listFeaturesAsync()` method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.
