Compute V1 Client - Class RegionInstanceGroupManagersClient (1.22.0)

Reference documentation and code samples for the Compute V1 Client class RegionInstanceGroupManagersClient.

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.

Namespace

Google \ Cloud \ Compute \ V1 \ Client

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. At the moment, supports only `rest`. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'rest' => [...], ]; See the Google\ApiCore\Transport\RestTransport::build() method for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.
`↳ logger`	`false\|LoggerInterface` A PSR-3 compliant logger. If set to false, logging is disabled, ignoring the 'GOOGLE_SDK_PHP_LOGGING' environment flag

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.

The async variant is RegionInstanceGroupManagersClient::abandonInstancesAsync() .

Parameters

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 regional managed instance group can contain up to 2000 instances.

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.

The async variant is RegionInstanceGroupManagersClient::patchAsync() .

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.

resize

Changes the intended size of 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 one or more instances. The resize operation is marked DONE if the resize request is successful. The underlying actions take additional time. You must separately verify the status of the creating or deleting actions 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.

resumeInstances

Flags the specified instances in the managed instance group to be resumed. This method increases the targetSize and decreases the targetSuspendedSize of the managed instance group by the number of instances that you resume. The resumeInstances operation is marked DONE if the resumeInstances request is successful. The underlying actions take additional time. You must separately verify the status of the RESUMING action with the listmanagedinstances method. In this request, you can only specify instances that are suspended. For example, if an instance was previously suspended using the suspendInstances method, it can be resumed using the resumeInstances method. If a health check is attached to the managed instance group, the specified instances will be verified as healthy after they are resumed. You can specify a maximum of 1000 instances with this method per request.

The async variant is RegionInstanceGroupManagersClient::resumeInstancesAsync() .

Flags the specified instances in the managed instance group to be started.

stopInstances

Flags the specified instances in the managed instance group to be immediately stopped. You can only specify instances that are running in this request. This method reduces the targetSize and increases the targetStoppedSize of the managed instance group by the number of instances that you stop. The stopInstances operation is marked DONE if the stopInstances request is successful. The underlying actions take additional time. You must separately verify the status of the STOPPING action with the listmanagedinstances method. If the standbyPolicy.initialDelaySec field is set, the group delays stopping the instances until initialDelaySec have passed from instance.creationTimestamp (that is, when the instance was created). This delay gives your application time to set itself up and initialize on the instance. If more than initialDelaySec seconds have passed since instance.creationTimestamp when this method is called, there will be zero delay. 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 stopped. Stopped instances can be started using the startInstances method. You can specify a maximum of 1000 instances with this method per request.
