• configmap for dso.mil now contains basic zone data to test local resolution on TCP 5353
• Corefile defines domain and port
• Corefile mounts to /etc/coredns/corefile/Corefile
• Zone files for $DOMAIN will mount to /etc/coredns/zones/$DOMAIN/$DOMAIN in order to consolidate the location of config files
• coredns service defines the protocol and port for dns per domain

TODO:

2. DNSSEC signing
3. Istio (and all therein)
4. Forwarding server to handle client requests.
