Compute V1 Client - Class InstanceGroupsClient (1.22.0)

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

Service Description: The InstanceGroups 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

addInstances

Adds a list of instances to the specified instance group. All of the instances in the instance group must be in the same network/subnetwork. Read Adding instances for more information.

The async variant is InstanceGroupsClient::addInstancesAsync() .
