* hello folks. I use nodepool connect openstack provider occur ssh connect error. my openstack cloud configure public and prviate netowrk. instance create by nodepool wouldn't assign public float-ip automatically. but nodepool would ssh to private network. so ssh failed. log like follow. what should do let nodepool create float-ip and attach to instance.
on openstck, I create instance manually, it wouldn't assign float-ip automatically. I need generate float-ip and attach to insance, then I can ssh to instance. and when I want create independent float-ip. after a moment, it would be automatic deleted by openstack, is there have config to set?
