Product Reference

Service Description: The RegionInstanceGroupManagers 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 (RegionInstanceGroupManagersClient regionInstanceGroupManagersClient =
     RegionInstanceGroupManagersClient.create()) {
   String project = "project-309310695";
   String region = "region-934795532";
   String instanceGroupManager = "instanceGroupManager-388242077";
   InstanceGroupManager response =
       regionInstanceGroupManagersClient.get(project, region, instanceGroupManager);
 }
 

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

Method	Description	Method Variants
AbandonInstances	Flags the specified instances to be immediately 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.	Request object method variants only take one parameter, a request object, which must be constructed before the call. abandonInstancesAsync(AbandonInstancesRegionInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. abandonInstancesAsync(String project, String region, String instanceGroupManager, RegionInstanceGroupManagersAbandonInstancesRequest regionInstanceGroupManagersAbandonInstancesRequestResource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. abandonInstancesOperationCallable() abandonInstancesCallable()

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 RegionInstanceGroupManagersSettings 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
 RegionInstanceGroupManagersSettings regionInstanceGroupManagersSettings =
     RegionInstanceGroupManagersSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 RegionInstanceGroupManagersClient regionInstanceGroupManagersClient =
     RegionInstanceGroupManagersClient.create(regionInstanceGroupManagersSettings);
 

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
 RegionInstanceGroupManagersSettings regionInstanceGroupManagersSettings =
     RegionInstanceGroupManagersSettings.newBuilder().setEndpoint(myEndpoint).build();
 RegionInstanceGroupManagersClient regionInstanceGroupManagersClient =
     RegionInstanceGroupManagersClient.create(regionInstanceGroupManagersSettings);

Beta

The surface for long-running operations is not stable yet and may change in the future.

This feature is covered by the Pre-GA Offerings Terms of the Terms of Service. Pre-GA libraries might have limited support, and changes to pre-GA libraries might not be compatible with other pre-GA versions. For more information, see the launch stage descriptions.

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.

patchOperationCallable()

public final OperationCallable<PatchRegionInstanceGroupManagerRequest,Operation,Operation> patchOperationCallable()

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.
