Hook for Google Compute Engine APIs.

All the methods in the hook where project_id is used must be called with keyword arguments rather than positional.

get_conn()[source]

Retrieves connection to Google Compute Engine.

Returns

Google Compute Engine services object

Return type

dict

get_compute_instance_template_client()[source]

Returns Compute Engine Instance Template Client.

get_compute_instance_client()[source]

Returns Compute Engine Instance Client.

insert_instance_template(body, request_id=None, project_id=PROVIDE_PROJECT_ID, retry=None, timeout=None, metadata=())[source]

Creates Instance Template using body specified.

Must be called with keyword arguments rather than positional.

Parameters

  • body (dict) – Instance Template representation as an object.

  • request_id (str | None) – Unique request_id that you might add to achieve full idempotence (for example when client call times out repeating the request with the same request id will not create a new instance template again) It should be in UUID format as defined in RFC 4122

  • project_id (str) – Google Cloud project ID where the Compute Engine Instance Template exists. If set to None or missing, the default project_id from the Google Cloud connection is used.

  • retry (google.api_core.retry.Retry | None) – A retry object used to retry requests. If None is specified, requests will not be retried.

  • timeout (float | None) – The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

  • metadata (Sequence[tuple[str, str]]) – Additional metadata that is provided to the method.

delete_instance_template(resource_id, request_id=None, project_id=PROVIDE_PROJECT_ID, retry=None, timeout=None, metadata=())[source]
