public class ClusterControllerClient implements BackgroundResource

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

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (ClusterControllerClient clusterControllerClient = ClusterControllerClient.create()) {
   String projectId = "projectId-894832108";
   String region = "region-934795532";
   String clusterName = "clusterName-1141738587";
   Cluster response = clusterControllerClient.getCluster(projectId, region, clusterName);
 }
 

Note: close() needs to be called on the ClusterControllerClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of ClusterControllerSettings to create(). For example:

To customize credentials:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);
 

To customize the endpoint:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newBuilder().setEndpoint(myEndpoint).build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ClusterControllerSettings clusterControllerSettings =
     ClusterControllerSettings.newHttpJsonBuilder().build();
 ClusterControllerClient clusterControllerClient =
     ClusterControllerClient.create(clusterControllerSettings);

Parameters
Name	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. 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 = *

updateMask	FieldMask Required. Specifies the path, relative to Cluster, of the field to update. For example, to change the number of workers in a cluster to 5, the update_mask parameter would be specified as config.worker_config.num_instances, and the PATCH request body would specify the new value, as follows: { "config":{ "workerConfig":{ "numInstances":"5" } } } Similarly, to change the number of preemptible workers in a cluster to 5, the update_mask parameter would be config.secondary_worker_config.num_instances, and the PATCH request body would be set as follows: { "config":{ "secondaryWorkerConfig":{ "numInstances":"5" } } } <strong>Note:</strong> Currently, only the following fields can be updated: <table> <tbody> <tr> <td><strong>Mask</strong></td> <td><strong>Purpose</strong></td> </tr> <tr> <td><strong><em>labels</em></strong></td> <td>Update labels</td> </tr> <tr> <td><strong><em>config.worker_config.num_instances</em></strong></td> <td>Resize primary worker group</td> </tr> <tr> <td><strong><em>config.secondary_worker_config.num_instances</em></strong></td> <td>Resize secondary worker group</td> </tr> <tr> <td>config.autoscaling_config.policy_uri</td><td>Use, stop using, or change autoscaling policies</td> </tr> </tbody> </table>
