To configure correct DNS settings on compute node use:
# First test DNS resolution via master using:
#:<pre>
#:: nslookup node<n>.<private-zone> <master-private-ip>
#:</pre>
# Then configure appropriate DNS and search domain using:
#:<pre>
#::  resolvectl domain <private-interface> <private-zone>
#::  resolvectl dns <private-interface> <master-private-ip>
#:</pre>
# Test by using:
#:<pre>
#:: ping master
#:: ping node<n>
#:</pre>
# Resolvectl based settings don't persist after reboot.  For persistent settings launch following as root user:
#:<pre>
#:: sudo nm-connection-editor
#:</pre>
#: and change appropriate interface DNS and search settings using the editor.
# Optionally, Reboot the node and validate DNS and domain settings are coming properly after reboot.
