Also dns
resolving only works on the cluster node, and not on the other nodes.
I tried fresh install with HA embedded db and also server, agent options.
The dns server address 10.43.0.10
is only accessible from cluster node ( by ssh to node) and pods on this cluster node (by running pods on this node).
And is not accessible from pods on other nodes (by running pods on other nodes) or other nodes (by ssh to other nodes).
