Instantiate

Instantiates a template and begins execution

5 variables
11 variables

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.On successful completion, Operation.response will be Empty

Authorization

To use this building block you will have to grant access to at least one of the following scopes:

  • View and manage your data across Google Cloud Platform services

Input

This building block consumes 5 input parameters

  = Parameter name
  = Format

name STRING Required

Required. The "resource name" of the workflow template, as described in https://cloud.google.com/apis/design/resource_names of the form projects/{project_id}/regions/{region}/workflowTemplates/{template_id}

requestId STRING

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 (https://en.wikipedia.org/wiki/Universally_unique_identifier).The tag must contain only letters (a-z, A-Z), numbers (0-9), underscores (_), and hyphens (-). The maximum length is 40 characters

version INTEGER

Optional. The version of workflow template to instantiate. If specified, the workflow will be instantiated only if the current version of the workflow template has the supplied version.This option cannot be used to instantiate a previous version of workflow template

parameters OBJECT

Optional. Map from parameter names to values that should be used for those parameters. Values may not exceed 100 characters

parameters.customKey.value STRING Required

Optional. Map from parameter names to values that should be used for those parameters. Values may not exceed 100 characters

Output

This building block provides 11 output parameters

  = Parameter name
  = Format

done BOOLEAN

If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available

response OBJECT

The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse

response.customKey.value ANY

The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse

name STRING

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id}

error OBJECT

The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC (https://github.com/grpc). Each Status message contains three pieces of data: error code, error message, and error details.You can find out more about this error model and how to work with it in the API Design Guide (https://cloud.google.com/apis/design/errors)

error.message STRING

A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client

error.details[] OBJECT

error.details[].customKey.value ANY

error.code INTEGER

The status code, which should be an enum value of google.rpc.Code

metadata OBJECT

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any

metadata.customKey.value ANY

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any
