+**master + any-node** - Schedule to control-plane nodes.
+
+**system + system** - Schedule to first matching node: NodeGroup/virtualization, NodeGroup/system and then control-plane.
+
+**any-node** - Schedule to any node, including control-plane.
+
+TODO d8 helm templates adds HA specifics, research and add them here.

+TODO remove NodeGroup/virtualization when removed from helm templates.
