openstack.compute.v2.service

The Service Class

The Service class inherits from Resource.

class openstack.compute.v2.service.Service(_synchronized=False, connection=None, **attrs)

The base resource

Parameters:

  • _synchronized (bool) – This is not intended to be used directly. See new() and existing().

  • connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of self._connection in Resource code should protect itself with a check for None.

classmethod find(session, name_or_id, ignore_missing=True, **params)

Find a resource by its name or id.

Parameters:

  • session (Adapter) – The session to use for making this request.

  • name_or_id – This resource’s identifier, if needed by the request. The default is None.

  • ignore_missing (bool) – When set to False NotFoundException will be raised when the resource does not exist. When set to True, None will be returned when attempting to find a nonexistent resource.

  • list_base_path (str) – base_path to be used when need listing resources.

  • microversion (str) – API version to override the negotiated one.

  • params (dict) – Any additional parameters to be passed into underlying methods, such as to existing() in order to pass on URI parameters.

Returns:

The Resource object matching the given name or id or None if nothing matches.

Raises:

openstack.exceptions.DuplicateResource if more than one resource is found for this request.

Raises:

openstack.exceptions.NotFoundException if nothing is found and ignore_missing is False.

commit(session, prepend_key=False, *args, **kwargs)

Commit the state of the instance to the remote resource.

Parameters:
