Class NodeGroupControllerClient (4.44.0)

GitHub RepositoryProduct ReferenceREST DocumentationRPC Documentation

Service Description: The NodeGroupControllerService provides methods to manage node groups of Compute Engine managed 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 (NodeGroupControllerClient nodeGroupControllerClient = NodeGroupControllerClient.create()) {
   NodeGroupName name = NodeGroupName.of("[PROJECT]", "[REGION]", "[CLUSTER]", "[NODE_GROUP]");
   NodeGroup response = nodeGroupControllerClient.getNodeGroup(name);
 }
 

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

Methods
Method Description Method Variants

CreateNodeGroup

Creates a node group in a cluster. The returned Operation.metadata is NodeGroupOperationMetadata.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • createNodeGroupAsync(CreateNodeGroupRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • createNodeGroupAsync(ClusterRegionName parent, NodeGroup nodeGroup, String nodeGroupId)

  • createNodeGroupAsync(String parent, NodeGroup nodeGroup, String nodeGroupId)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • createNodeGroupOperationCallable()

  • createNodeGroupCallable()

ResizeNodeGroup

Resizes a node group in a cluster. The returned Operation.metadata is NodeGroupOperationMetadata.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • resizeNodeGroupAsync(ResizeNodeGroupRequest request)

Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service.

  • resizeNodeGroupAsync(String name, int size)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • resizeNodeGroupOperationCallable()

  • resizeNodeGroupCallable()

GetNodeGroup

Gets the resource representation for a node group in a cluster.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getNodeGroup(GetNodeGroupRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getNodeGroup(NodeGroupName name)

  • getNodeGroup(String name)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getNodeGroupCallable()

SetIamPolicy

Sets the access control policy on the specified resource. Replacesany existing policy.

Can return NOT_FOUND, INVALID_ARGUMENT, and PERMISSION_DENIEDerrors.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • setIamPolicy(SetIamPolicyRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • setIamPolicyCallable()

GetIamPolicy

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

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getIamPolicy(GetIamPolicyRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getIamPolicyCallable()

TestIamPermissions

Returns permissions that a caller has on the specified resource. If theresource does not exist, this will return an empty set ofpermissions, not a NOT_FOUND error.

Note: This operation is designed to be used for buildingpermission-aware UIs and command-line tools, not for authorizationchecking. This operation may "fail open" without warning.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • testIamPermissions(TestIamPermissionsRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • testIamPermissionsCallable()

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 NodeGroupControllerSettings 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
 NodeGroupControllerSettings nodeGroupControllerSettings =
     NodeGroupControllerSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 NodeGroupControllerClient nodeGroupControllerClient =
     NodeGroupControllerClient.create(nodeGroupControllerSettings);
 

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
 NodeGroupControllerSettings nodeGroupControllerSettings =
     NodeGroupControllerSettings.newBuilder().setEndpoint(myEndpoint).build();
 NodeGroupControllerClient nodeGroupControllerClient =
     NodeGroupControllerClient.create(nodeGroupControllerSettings);
 

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
 NodeGroupControllerSettings nodeGroupControllerSettings =
     NodeGroupControllerSettings.newHttpJsonBuilder().build();
 NodeGroupControllerClient nodeGroupControllerClient =
     NodeGroupControllerClient.create(nodeGroupControllerSettings);

testIamPermissions(TestIamPermissionsRequest request)

public final TestIamPermissionsResponse testIamPermissions(TestIamPermissionsRequest request)

Returns permissions that a caller has on the specified resource. If theresource does not exist, this will return an empty set ofpermissions, not a NOT_FOUND error.

Note: This operation is designed to be used for buildingpermission-aware UIs and command-line tools, not for authorizationchecking. This operation may "fail open" without warning.
