Reference documentation and code samples for the Google Cloud Dataproc V1 Client class AutoscalingPolicyServiceClient.
Service Description: The API interface for managing autoscaling policies in the Dataproc 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:
$autoscalingPolicyServiceClient = new AutoscalingPolicyServiceClient();
try {
$formattedParent = $autoscalingPolicyServiceClient->regionName('[PROJECT]', '[REGION]');
$policy = new AutoscalingPolicy();
$response = $autoscalingPolicyServiceClient->createAutoscalingPolicy($formattedParent, $policy);
} finally {
$autoscalingPolicyServiceClient->close();
}
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 parseName method to extract the individual identifiers contained within formatted names that are returned by the API.
This service has a new (beta) implementation. See Google\Cloud\Dataproc\V1\Client\AutoscalingPolicyServiceClient to use the new surface.
Namespace
Google \ Cloud \ Dataproc \ V1Methods
__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 |
↳ 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. May be either the string |
↳ 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 = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods 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. |

|
policy |
Google\Cloud\Dataproc\V1\AutoscalingPolicy
Required. The autoscaling policy to create. |
optionalArgs |
array
Optional. |

* period for which to remove workers. A scale-down factor of 1 will result in
