We produce 3 Docker images
- sslip.io-dns-server (run sslip.io in a container)
- fedora-golang-bosh (CI testing)
- fedora-ruby-bind-utils (nameserver testing)
We place the Dockerfiles under `Docker/` with a subdirectory name
corresponding to the Docker image name.
TODO: we need to tidy the Dockerfiles under `k8s`, but we'll leave that
for another day.
