I had to setup an cluster on CentOS virtual machines, and I did as I found on internet; at first seems like is working well, but recently i'm getting too much trouble with istio and communications. Well, my major problem is that I cant reach to a VM who has the database, the master node and the worker nodes can reach and telnet to the database VM, but the pods cant. Do I have to set some kubernetes network config? Thanks (:

Make sure that the Coredns is using host's /etc/resolv.conf https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/ – Rakesh Gupta Dec 17 '21 at 20:53
