To configure correct DNS settings on compute node use:

  1. First test DNS resolution via master using: 
    nslookup node<n>.<private-zone> <master-private-ip>
  2. Then configure appropriate DNS and search domain using: 
    resolvectl domain <private-interface> <private-zone>
    

    resolvectl dns <private-interface> <master-private-ip>
  3. Test by using: 
    ping master
    

    ping node<n>
