Subject: [PATCH] k8s: deployment & nodePort service

- nodePort service is merely a proof-of-concept; this won't be the final
  form the service takes. The port needs to be 53, not 32767.
- the deployment doesn't include the nginx webserver, merely the DNS
  server. Also, I had trouble connecting both UDP & TCP to port 53,
  so I chose UDP.
