Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the Workflows Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# Modify the configuration for all Workflows clients
::Google::Cloud::Workflows::V1::Workflows::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the Workflows 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 Client.configure.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns

#create_workflow

def create_workflow(request, options = nil) -> ::Gapic::Operation
def create_workflow(parent: nil, workflow: nil, workflow_id: nil) -> ::Gapic::Operation

Creates a new workflow. If a workflow with the specified name already exists in the specified project and location, the long running operation returns a [ALREADY_EXISTS][google.rpc.Code.ALREADY_EXISTS] error.

Overloads 
def create_workflow(request, options = nil) -> ::Gapic::Operation
Pass arguments to create_workflow via a request object, either of type CreateWorkflowRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Workflows::V1::CreateWorkflowRequest, ::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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def create_workflow(parent: nil, workflow: nil, workflow_id: nil) -> ::Gapic::Operation
Pass arguments to create_workflow 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) — Required. Project and location in which the workflow should be created. Format: projects/{project}/locations/{location}
  • workflow (::Google::Cloud::Workflows::V1::Workflow, ::Hash) — Required. Workflow to be created.
  • workflow_id (::String) —

    Required. The ID of the workflow to be created. It has to fulfill the following requirements:

    • Must contain only letters, numbers, underscores and hyphens.
    • Must start with a letter.
    • Must be between 1-64 characters.
    • Must end with a number or a letter.
    • Must be unique within the customer project and location.
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) — if the RPC is aborted.
