Ask HN: Simple paid deployment service for monetizing an open source app?

I have an open source app that's moderately successful and a few folks have shown interest in paying for a cloud/hosted version. However, setting up and managing a cloud service isn't something I'm particularly interested in doing, so I've been looking for an out-of-the-box option that seems like it should exist.

Basically it'd allow me to provide a docker image and config info, maybe some other setup, and then allow the user to easily deploy it on infrastructure somewhere.

It'd be awesome if they could choose the infrastructure they want, pay them directly, and just pay me a separate fee for on-going support, early updates, etc.

Things are containerized enough these days it seems like it should be possible, but I haven't found anything like this.

Any recommendations?
