This looks really great, is anyone using it for a real app? It does require you to build in support for a given service though - would be perfect if someone made a package that let you self-deploy instantly to any of the popular services or VPS providers, so that users could instantly self-deploy. This was the promise of containers but it doesn't feel quite ready for that yet.
I'm doing something much simpler here - using cloud config on DO to deploy to CoreOS without containers on a single instance - just a systemd service (as he says in this talk, containers feel like overkill for deploying Go apps). kubernetes does look great for larger deploys though.
