Probably not quite what you're looking for but perhaps along the right lines (and it looks like they've added some products and maybe features) https://traefik.io/traefik/

The gist of it is Traefik is a reverse proxy that learns about your containers via configuration in the container only, so you can stand up additional services without rebooting everything. Still config heavy, but maybe less than some other approaches.

Traefik is pretty cool. Can get you very far with forward auth plugins.

I use it extensively already :)

A few labels and magic!
