docker-coredns

Dockerized coredns.

Whereas official coredns docker image is based on a scratch image, this image based on Alpine. This slight improvement enables shell scripts to be used as the entrypoint, to help to dynamically generate coredns config files, and help with debugging. The coredns binaries are sourced from their official images.
