DNS server on bastion host should serve wildcard for apps #290

Open jeremyeder opened 7 years ago

jeremyeder commented 7 years ago

The Heat templates deploy a DNS server. Can this server also (optionally) serve out the wildcard entry required for openshift routes?

juddmaltin-dell commented 7 years ago

Deployment docs warn that this could cause pods and containers that lookup DNS there to get confused.

Warning

In your /etc/resolv.conf file on each node host, ensure that the DNS server that has the wildcard entry is not listed as a nameserver or that the wildcard domain is not listed in the search list. Otherwise, containers managed by OpenShift Container Platform may fail to resolve host names properly.

@jeremyeder iirc now those templates require an external dns and don't deploy one anymore.
