ClusterControllerClient

ClusterControllerClient

The ClusterControllerService provides methods to manage clusters of Compute Engine instances.

Constructor

new ClusterControllerClient(optionsopt, gaxInstanceopt)

Construct an instance of ClusterControllerClient.

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

gaxInstance gax <optional>

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 ClusterControllerClient({fallback: true}, gax);

Members

apiEndpoint

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

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

batchPath(project, location, batch) → {string}

Return a fully-qualified batch resource name string.

Parameters:
Name Type Description
project string
location string
batch string
Returns:
Type Description
string

Resource name string.

cancelOperation(request, optionsopt, callbackopt) → {Promise}

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
name string

The name of the operation resource to be cancelled.

options Object <optional>

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

callback function <optional>

The function which will be called with the result of the API call.

Returns:
Type Description
Promise
  • The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.
Example
```
const client = longrunning.operationsClient();
await client.cancelOperation({name: ''});
```

(async) checkCreateClusterProgress(name) → {Promise}

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

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.

deleteOperation(request, optionsopt, callbackopt) → {Promise}

Deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
name string

The name of the operation resource to be deleted.

options Object <optional>

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

callback function <optional>

The function which will be called with the result of the API call.

Returns:
Type Description
Promise
  • The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.
Example
```
const client = longrunning.operationsClient();
await client.deleteOperation({name: ''});
```

getIamPolicy(request, optionsopt, callbackopt) → {Promise}

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
resource string

REQUIRED: The resource for which the policy is being requested. See the operation documentation for the appropriate value for this field.

options Object <optional>

OPTIONAL: A GetPolicyOptions object for specifying options to GetIamPolicy. This field is only used by Cloud IAM.

This object should have the same structure as GetPolicyOptions.

options Object <optional>

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

callback function <optional>

The function which will be called with the result of the API call.

The second parameter to the callback is an object representing Policy.

Returns:
Type Description
Promise
  • The promise which resolves to an array. The first element of the array is an object representing Policy. The promise has a method named "cancel" which cancels the ongoing API call.

getOperation(request, optionsopt, callbackopt) → {Promise}

Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
name string

The name of the operation resource.

options Object <optional>

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

callback function <optional>

The function which will be called with the result of the API call.

The second parameter to the callback is an object representing google.longrunning.Operation.

Returns:
Type Description
Promise
  • The promise which resolves to an array. The first element of the array is an object representing google.longrunning.Operation. The promise has a method named "cancel" which cancels the ongoing API call.
Example
```
const client = longrunning.operationsClient();
const name = '';
const [response] = await client.getOperation({name});
// doThingsWith(response)
```

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.

listClustersAsync(request, optionsopt) → {Object}

Equivalent to listClusters, 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
projectId string

Required. The ID of the Google Cloud Platform project that the cluster belongs to.

region string

Required. The Dataproc region in which to handle the request.

filter string <optional>

Optional. A filter constraining the clusters to list. Filters are case-sensitive and have the following syntax:

field = value [AND [field = value]] ...

where field is one of status.state, clusterName, or labels.[KEY], and [KEY] is a label key. value can be * to match all values. status.state can be one of the following: ACTIVE, INACTIVE, CREATING, RUNNING, ERROR, DELETING, or UPDATING. ACTIVE contains the CREATING, UPDATING, and RUNNING states. INACTIVE contains the DELETING and ERROR states. clusterName is the name of the cluster provided at creation time. Only the logical AND operator is supported; space-separated items are treated as having an implicit AND operator.

Example filter:

status.state = ACTIVE AND clusterName = mycluster AND labels.env = staging AND labels.starred = *

pageSize number <optional>

Optional. The standard List page size.

pageToken string <optional>

Optional. The standard List page token.

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 Cluster. 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.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
projectId string

Required. The ID of the Google Cloud Platform project that the cluster belongs to.

region string

Required. The Dataproc region in which to handle the request.

filter string <optional>

Optional. A filter constraining the clusters to list. Filters are case-sensitive and have the following syntax:

field = value [AND [field = value]] ...

where field is one of status.state, clusterName, or labels.[KEY], and [KEY] is a label key. value can be * to match all values. status.state can be one of the following: ACTIVE, INACTIVE, CREATING, RUNNING, ERROR, DELETING, or UPDATING. ACTIVE contains the CREATING, UPDATING, and RUNNING states. INACTIVE contains the DELETING and ERROR states. clusterName is the name of the cluster provided at creation time. Only the logical AND operator is supported; space-separated items are treated as having an implicit AND operator.

Example filter:

status.state = ACTIVE AND clusterName = mycluster AND labels.env = staging AND labels.starred = *

pageSize number <optional>

Optional. The standard List page size.

pageToken string <optional>

Optional. The standard List page token.

options object <optional>

Call options. See CallOptions for more details.

Returns:
Type Description
Stream

An object stream which emits an object representing Cluster 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 listClustersAsync() method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.

listOperationsAsync(request, optionsopt) → {Object}

Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED. Returns an iterable object.

For-await-of syntax is used with the iterable to recursively get response element on-demand.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
name string

The name of the operation collection.

filter string

The standard list filter.

pageSize number <optional>

The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.

options Object <optional>

Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

Returns:
Type Description
Object

An iterable Object that conforms to iteration protocols.

Example
```
const client = longrunning.operationsClient();
for await (const response of client.listOperationsAsync(request));
// doThingsWith(response)
```
