For those charts , we will change node_selector_key to some new key like openstack-additional-plane. In AIO (Simplex /Duplex) system : The Openstack- additional-plane is not enabled. Then those services should not be started Shall we force deny if adding label "Openstack- additional-plane" ? And for multi-node, The Openstack- additional-plane is enabled. Then those services should be started . is this proper approach ? Thanks. BR Austin Sun.
