Instance Method Details

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

Configure the WorkflowsService 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.

#run_pipeline(request, options = nil) ⇒ ::Gapic::Operation #run_pipeline(parent: nil, pipeline: nil, labels: nil, pub_sub_topic: nil) ⇒ ::Gapic::Operation

Runs a pipeline. The returned Operation's [metadata] [google.longrunning.Operation.metadata] field will contain a google.cloud.lifesciences.v2beta.Metadata object describing the status of the pipeline execution. The response field will contain a google.cloud.lifesciences.v2beta.RunPipelineResponse object if the pipeline completes successfully.

Note: Before you can use this method, the Life Sciences Service Agent must have access to your project. This is done automatically when the Cloud Life Sciences API is first enabled, but if you delete this permission you must disable and re-enable the API to grant the Life Sciences Service Agent the required permissions. Authorization requires the following Google IAM permission:

  • lifesciences.workflows.run

Examples:

Basic example

require "google/cloud/life_sciences/v2beta"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::LifeSciences::V2beta::WorkflowsService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::LifeSciences::V2beta::RunPipelineRequest.new

# Call the run_pipeline method.
result = client.run_pipeline 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?
  p result.response
else
  puts "Error!"
end

Overloads:

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

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

    Parameters:

    • request (::Google::Cloud::LifeSciences::V2beta::RunPipelineRequest, ::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.

  • #run_pipeline(parent: nil, pipeline: nil, labels: nil, pub_sub_topic: nil) ⇒ ::Gapic::Operation

    Pass arguments to run_pipeline 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) —

      The project and location that this request should be executed against.

    • pipeline (::Google::Cloud::LifeSciences::V2beta::Pipeline, ::Hash) (defaults to: nil) —

      Required. The description of the pipeline to run.

    • labels (::Hash{::String => ::String}) (defaults to: nil) —

      User-defined labels to associate with the returned operation. These labels are not propagated to any Google Cloud Platform resources used by the operation, and can be modified at any time.

      To associate labels with resources created while executing the operation, see the appropriate resource message (for example, VirtualMachine).

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

      The name of an existing Pub/Sub topic. The server will publish messages to this topic whenever the status of the operation changes. The Life Sciences Service Agent account must have publisher permissions to the specified topic or notifications will not be sent.

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.
