Returns:

updated port object, including all fields.

update_portgroup(context, portgroup_obj, topic=None)[source]¶

class ironic.conductor.rpcapi.LocalContext[source]¶

Bases: object

Context to make calls to a local conductor.

call(context, rpc_call_name, **kwargs)[source]¶: Make a local conductor call.

cast(context, rpc_call_name, **kwargs)[source]¶

Make a local conductor call.

It is expected that the underlying call uses a thread to avoid blocking the caller.

Any exceptions are logged and ignored.
