Photon OS 4.0 as kubernets node - port 10250 issue

[igorbarsanti]

I'm running a kubernetes cluster, now with only 1 worker node.

The control-plane runs on ubuntu 20.04, the node runs Photon OS 4.0 GA from VMWare.

I've successfully added the node and deployed pods but I cannot reach port 10250 on the node; I've added the port to iptables, but I can only connect from node shell with 127.0.0.1:10250, I cannot reach the port from control-plane and I cannot see logs on node1 pods either execute a command...

If I try a telnet node 10250 from control-plane host the packets arrive to destination because I can see them with tcpdump.

Any idea?

Thanks,

Igor
