Ask HN: Package and sell self-hosted web-app?

I'm working on a SaaS product that, by the nature of it, doesn't make sense to do a cloud model. Instead I'd like to sell yearly licenses for it, and distribute a container or some easy-to-consume image.

The Docker store seems perfect for this, but I'm not seeing a lot of containers people charge outright for (which gives me flashbacks to the App Store). I'm wondering how folks here package up a server+DB for distribution and sale?
