Class InstanceGroupManagersClient (1.37.0)

public class InstanceGroupManagersClient implements BackgroundResource

Service Description: The InstanceGroupManagers API.

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 (InstanceGroupManagersClient instanceGroupManagersClient =
     InstanceGroupManagersClient.create()) {
   String project = "project-309310695";
   String zone = "zone3744684";
   String instanceGroupManager = "instanceGroupManager-388242077";
   InstanceGroupManager response =
       instanceGroupManagersClient.get(project, zone, instanceGroupManager);
 }

Note: close() needs to be called on the InstanceGroupManagersClient 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:

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.
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.
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 InstanceGroupManagersSettings 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
 InstanceGroupManagersSettings instanceGroupManagersSettings =
     InstanceGroupManagersSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 InstanceGroupManagersClient instanceGroupManagersClient =
     InstanceGroupManagersClient.create(instanceGroupManagersSettings);

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
 InstanceGroupManagersSettings instanceGroupManagersSettings =
     InstanceGroupManagersSettings.newBuilder().setEndpoint(myEndpoint).build();
 InstanceGroupManagersClient instanceGroupManagersClient =
     InstanceGroupManagersClient.create(instanceGroupManagersSettings);

Methods

abandonInstancesAsync(AbandonInstancesInstanceGroupManagerRequest request)

public final OperationFuture<Operation,Operation> abandonInstancesAsync(AbandonInstancesInstanceGroupManagerRequest request)

Flags the specified instances to be removed from the managed instance group. Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

deleteInstancesAsync(DeleteInstancesInstanceGroupManagerRequest request)

public final OperationFuture<Operation,Operation> deleteInstancesAsync(DeleteInstancesInstanceGroupManagerRequest request)

Flags the specified instances in the managed instance group for immediate deletion. The instances are also removed from any target pools of which they were a member. This method reduces the targetSize of the managed instance group by the number of instances that you delete. This operation is marked as DONE when the action is scheduled even if the instances are still being deleted. You must separately verify the status of the deleting action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

patchAsync(PatchInstanceGroupManagerRequest request)

public final OperationFuture<Operation,Operation> patchAsync(PatchInstanceGroupManagerRequest request)

Updates a managed instance group using the information that you specify in the request. This operation is marked as DONE when the group is patched even if the instances in the group are still in the process of being patched. You must separately verify the status of the individual instances with the listManagedInstances method. This method supports PATCH semantics and uses the JSON merge patch format and processing rules. If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, see Updating instances in a MIG.

Flags the specified VM instances in the managed instance group to be immediately recreated. Each instance is recreated using the group's current configuration. This operation is marked as DONE when the flag is set even if the instances have not yet been recreated. You must separately verify the status of each instance by checking its currentAction field; for more information, see Checking the status of managed instances. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

resizeAsync(ResizeInstanceGroupManagerRequest request)

public final OperationFuture<Operation,Operation> resizeAsync(ResizeInstanceGroupManagerRequest request)

Resizes the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes instances. The resize operation is marked DONE when the resize actions are scheduled even if the group has not yet added or deleted any instances. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method. When resizing down, the instance group arbitrarily chooses the order in which VMs are deleted. The group takes into account some VM attributes when making the selection including: + The status of the VM instance. + The health of the VM instance. + The instance template version the VM is based on. + For regional managed instance groups, the location of the VM instance. This list is subject to change. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted.
