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().

Method	Description	Method Variants
AbandonInstances	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.	Request object method variants only take one parameter, a request object, which must be constructed before the call. abandonInstancesAsync(AbandonInstancesInstanceGroupManagerRequest 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 zone, String instanceGroupManager, InstanceGroupManagersAbandonInstancesRequest instanceGroupManagersAbandonInstancesRequestResource) 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()
AggregatedList	Retrieves the list of managed instance groups and groups them by zone.

DeleteInstances	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.

Insert	Creates a managed instance group using the information that you specify in the request. After the group is created, instances in the group are created using the specified instance template. This operation is marked as DONE when the group is created even if the instances in the group have not yet been created. You must separately verify the status of the individual instances with the listmanagedinstances method. A managed instance group can have up to 1000 VM instances per group. Please contact Cloud Support if you need an increase in this limit.

ListManagedInstances	Lists all of the instances in the managed instance group. Each instance in the list has a currentAction, which indicates the action that the managed instance group is performing on the instance. For example, if the group is still creating an instance, the currentAction is CREATING. If a previous action failed, the list displays the errors for that failed action. The orderBy query parameter is not supported. The pageToken query parameter is supported only in the alpha and beta API and only if the group's listManagedInstancesResults field is set to PAGINATED.	Request object method variants only take one parameter, a request object, which must be constructed before the call. listManagedInstances(ListManagedInstancesInstanceGroupManagersRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. listManagedInstances(String project, String zone, String instanceGroupManager) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. listManagedInstancesPagedCallable() listManagedInstancesCallable()

Patch	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.	Request object method variants only take one parameter, a request object, which must be constructed before the call. patchAsync(PatchInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. patchAsync(String project, String zone, String instanceGroupManager, InstanceGroupManager instanceGroupManagerResource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. patchOperationCallable() patchCallable()

RecreateInstances	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.	Request object method variants only take one parameter, a request object, which must be constructed before the call. recreateInstancesAsync(RecreateInstancesInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. recreateInstancesAsync(String project, String zone, String instanceGroupManager, InstanceGroupManagersRecreateInstancesRequest instanceGroupManagersRecreateInstancesRequestResource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. recreateInstancesOperationCallable() recreateInstancesCallable()
Resize	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.	Request object method variants only take one parameter, a request object, which must be constructed before the call. resizeAsync(ResizeInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. resizeAsync(String project, String zone, String instanceGroupManager, 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. resizeOperationCallable() resizeCallable()
SetInstanceTemplate	Specifies the instance template to use when creating new instances in this group. The templates for existing instances in the group do not change unless you run recreateInstances, run applyUpdatesToInstances, or set the group's updatePolicy.type to PROACTIVE.	Request object method variants only take one parameter, a request object, which must be constructed before the call. setInstanceTemplateAsync(SetInstanceTemplateInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. setInstanceTemplateAsync(String project, String zone, String instanceGroupManager, InstanceGroupManagersSetInstanceTemplateRequest instanceGroupManagersSetInstanceTemplateRequestResource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. setInstanceTemplateOperationCallable() setInstanceTemplateCallable()
SetTargetPools	Modifies the target pools to which all instances in this managed instance group are assigned. The target pools automatically apply to all of the instances in the managed instance group. This operation is marked DONE when you make the request even if the instances have not yet been added to their target pools. The change might take some time to apply to all of the instances in the group depending on the size of the group.	Request object method variants only take one parameter, a request object, which must be constructed before the call. setTargetPoolsAsync(SetTargetPoolsInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. setTargetPoolsAsync(String project, String zone, String instanceGroupManager, InstanceGroupManagersSetTargetPoolsRequest instanceGroupManagersSetTargetPoolsRequestResource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. setTargetPoolsOperationCallable() setTargetPoolsCallable()
UpdatePerInstanceConfigs	Inserts or updates per-instance configurations for the managed instance group. perInstanceConfig.name serves as a key used to distinguish whether to perform insert or patch.	Request object method variants only take one parameter, a request object, which must be constructed before the call. updatePerInstanceConfigsAsync(UpdatePerInstanceConfigsInstanceGroupManagerRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. updatePerInstanceConfigsAsync(String project, String zone, String instanceGroupManager, InstanceGroupManagersUpdatePerInstanceConfigsReq instanceGroupManagersUpdatePerInstanceConfigsReqResource) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. updatePerInstanceConfigsOperationCallable() updatePerInstanceConfigsCallable()

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);

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.

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.

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.

OperationFuture<Operation,Operation>

resizeAsync(String project, String zone, String instanceGroupManager, int size)

public final OperationFuture<Operation,Operation> resizeAsync(String project, String zone, String instanceGroupManager, int size)

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.

Parameters
Name	Description
project	String Project ID for this request.
zone	String The name of the zone where the managed instance group is located.
instanceGroupManager	String The name of the managed instance group.
size	int The number of running instances that the managed instance group should maintain at any given time. The group automatically adds or removes instances to maintain the number of instances specified by this parameter.
