Currently, if the bastion machine is assigned IP address with DHCP, it also receive the DNS server from DHCP
server. Although the resolv.conf can be updated by adding the bastion address through NetworkManager
ifcfg script, its address would be put below the DNS addresses from DHCP and that will make looking up a name
for the OCP cluster fail. To put it on the top in the generated resolv.conf, the following line should be added to the
/etc/dhcp/dhclient.conf:
prepend domain-name-servers [ip address of bastion];
A task would be needed to replace the generate dns with interface script.task if using DHCP.
