Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the WorkflowTemplateService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

#create_workflow_template(request, options = nil) ⇒ ::Google::Cloud::Dataproc::V1::WorkflowTemplate #create_workflow_template(parent: nil, template: nil) ⇒ ::Google::Cloud::Dataproc::V1::WorkflowTemplate

Creates new workflow template.

Examples:

Basic example

require "google/cloud/dataproc/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Dataproc::V1::WorkflowTemplateService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Dataproc::V1::CreateWorkflowTemplateRequest.new

# Call the create_workflow_template method.
result = client.create_workflow_template request

# The returned object is of type Google::Cloud::Dataproc::V1::WorkflowTemplate.
p result

Overloads:

  • #create_workflow_template(request, options = nil) ⇒ ::Google::Cloud::Dataproc::V1::WorkflowTemplate

    Pass arguments to create_workflow_template via a request object, either of type CreateWorkflowTemplateRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Dataproc::V1::CreateWorkflowTemplateRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_workflow_template(parent: nil, template: nil) ⇒ ::Google::Cloud::Dataproc::V1::WorkflowTemplate

    Pass arguments to create_workflow_template via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. The resource name of the region or location, as described in https://cloud.google.com/apis/design/resource_names.

      • For projects.regions.workflowTemplates.create, the resource name of the region has the following format: projects/{project_id}/regions/{region}

      • For projects.locations.workflowTemplates.create, the resource name of the location has the following format: projects/{project_id}/locations/{location}

    • template (::Google::Cloud::Dataproc::V1::WorkflowTemplate, ::Hash) (defaults to: nil) —

      Required. The Dataproc workflow template to create.

#instantiate_inline_workflow_template(request, options = nil) ⇒ ::Gapic::Operation #instantiate_inline_workflow_template(parent: nil, template: nil, request_id: nil) ⇒ ::Gapic::Operation

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.

Examples:

Basic example

require "google/cloud/dataproc/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Dataproc::V1::WorkflowTemplateService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Dataproc::V1::InstantiateInlineWorkflowTemplateRequest.new

# Call the instantiate_inline_workflow_template method.
result = client.instantiate_inline_workflow_template request

# The returned object is of type Gapic::Operation. You can use this
# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:

Overloads:

  • #instantiate_inline_workflow_template(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to instantiate_inline_workflow_template via a request object, either of type InstantiateInlineWorkflowTemplateRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Dataproc::V1::InstantiateInlineWorkflowTemplateRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #instantiate_inline_workflow_template(parent: nil, template: nil, request_id: nil) ⇒ ::Gapic::Operation

    Pass arguments to instantiate_inline_workflow_template via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. The resource name of the region or location, as described in https://cloud.google.com/apis/design/resource_names.

      • For projects.regions.workflowTemplates,instantiateinline, the resource name of the region has the following format: projects/{project_id}/regions/{region}

      • For projects.locations.workflowTemplates.instantiateinline, the resource name of the location has the following format: projects/{project_id}/locations/{location}

    • template (::Google::Cloud::Dataproc::V1::WorkflowTemplate, ::Hash) (defaults to: nil) —

      Required. The workflow template to instantiate.

    • request_id (::String) (defaults to: nil) —

      Optional. A tag that prevents multiple concurrent workflow instances with the same tag from running. This mitigates risk of concurrent instances started due to retries.

      It is recommended to always set this value to a UUID.

      The tag must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

#instantiate_workflow_template(request, options = nil) ⇒ ::Gapic::Operation #instantiate_workflow_template(name: nil, version: nil, request_id: nil, parameters: nil) ⇒ ::Gapic::Operation

Instantiates a template and begins execution.

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.

Examples:

Basic example

require "google/cloud/dataproc/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Dataproc::V1::WorkflowTemplateService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Dataproc::V1::InstantiateWorkflowTemplateRequest.new

# Call the instantiate_workflow_template method.
result = client.instantiate_workflow_template request

# The returned object is of type Gapic::Operation. You can use this
# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:
result.wait_until_done! timeout: 60
if result.response?

  puts "Error!"
