This is part of openshift/os#542 whch is part of openshift/os#477
Hopefully in the future we'll move the full release browser into Github and run it in app.ci, but for now this tiny service should be run by ART to backend the openshift/installer metadata.
I took the basic config from the currently internal https://gitlab.cee.redhat.com/coreos/release-browser and also used as a reference the code from https://github.com/cgwalters/os/commit/6b4cdd758300d62d3df37c436f7b626d27224fc4
After some investigation, it does seem like it's the current
nginx.conf from the release-browser repository that's running.
This runs a simple read-only service on port 8080 built via a Dockerfile.
To test locally you can e.g.:
$ podman build -t localhost/redirector .
$ podman run --name redirector -d -p 8080:8080 localhost/redirector
$ curl -L --head http://127.0.0.1:8080/art/storage/releases/rhcos-4.7/47.83.202012030221-0/x86_64/rhcos-47.83.202012030221-0-qemu.x86_64.qcow2.gz

Just needs a usual BuildConfig/Service/Route etc. that oc new-app will make happily.
