Method: googleapis.spanner.v1.projects.instanceConfigs.create

Creates an instance config and begins preparing it to be used. The returned long-running operation can be used to track the progress of preparing the new instance config. The instance config name is assigned by the caller. If the named instance config already exists, CreateInstanceConfig returns ALREADY_EXISTS. Immediately after the request returns: * The instance config is readable via the API, with all requested attributes. The instance config's reconciling field is set to true. Its state is CREATING. While the operation is pending: * Cancelling the operation renders the instance config immediately unreadable via the API. * Except for deleting the creating resource, all other attempts to modify the instance config are rejected. Upon completion of the returned operation: * Instances can be created using the instance configuration. * The instance config's reconciling field becomes false. Its state becomes READY. The returned long-running operation will have a name of the format /operations/ and can be used to track creation of the instance config. The metadata field type is CreateInstanceConfigMetadata. The response field type is InstanceConfig, if successful. Authorization requires spanner.instanceConfigs.create permission on the resource parent.

This method waits—the workflow execution is paused—until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field. See the Connectors reference.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. For more information about retries and long-running operations, refer to Understand connectors.

The polling policy for the long-running operation can be configured. To set the connector-specific parameters (connector_params), refer to Invoke a connector call.

Arguments

Parameters
parent	string Required. The name of the project in which to create the instance config. Values are of the form projects/.
body	object (CreateInstanceConfigRequest) Required.

Raised exceptions

Exceptions
ConnectionError	In case of a network problem (such as DNS failure or refused connection).
HttpError	If the response status is >= 400 (excluding 429 and 503).
TimeoutError	If a long-running operation takes longer to finish than the specified timeout limit.
TypeError	If an operation or function receives an argument of the wrong type.
ValueError	If an operation or function receives an argument of the right type but an inappropriate value. For example, a negative timeout.
OperationError	If the long-running operation finished unsuccessfully.
ResponseTypeError	If the long-running operation returned a response of the wrong type.

Response

If successful, the response contains an instance of Operation.
