Google Cloud Dataproc V1 Client - Class WorkflowTemplateServiceClient (3.4.0)

Reference documentation and code samples for the Google Cloud Dataproc V1 Client class WorkflowTemplateServiceClient.

Service Description: The API interface for managing Workflow Templates 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:

$workflowTemplateServiceClient = new WorkflowTemplateServiceClient();
try {
    $formattedParent = $workflowTemplateServiceClient->regionName('[PROJECT]', '[REGION]');
    $template = new WorkflowTemplate();
    $response = $workflowTemplateServiceClient->createWorkflowTemplate($formattedParent, $template);
} finally {
    $workflowTemplateServiceClient->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.

parseName

Parses a formatted name string and returns an associative array of the components in the name.

The following name formats are supported: Template: Pattern

  • location: projects/{project}/locations/{location}
  • projectLocationWorkflowTemplate: projects/{project}/locations/{location}/workflowTemplates/{workflow_template}
  • projectRegionWorkflowTemplate: projects/{project}/regions/{region}/workflowTemplates/{workflow_template}
  • region: projects/{project}/regions/{region}
  • workflowTemplate: projects/{project}/regions/{region}/workflowTemplates/{workflow_template}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.

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. May be either the string rest or grpc. Defaults to grpc if gRPC support is detected on the system. 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 = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.

↳ clientCertSource callable

instantiateInlineWorkflowTemplate

Instantiates a template and begins execution.

This method is equivalent to executing the sequence CreateWorkflowTemplate, InstantiateWorkflowTemplate, DeleteWorkflowTemplate.

The returned Operation can be used to track execution of workflow by polling operations.get. The Operation will complete when entire workflow is finished.

The running workflow can be aborted via operations.cancel. This will cause any inflight jobs to be cancelled and workflow-owned clusters to be deleted.

The Operation.metadata will be WorkflowMetadata. Also see Using WorkflowMetadata.

On successful completion, Operation.response will be Empty.
