This looks cool. I see under the "current limitations" section that it only supports a single node. Are there plans to change that? I'd imagine that database instances which got started on a single node deployment would be hard to migrate to a multi-node setup later on if they weren't originally spun up in that configuration (though ofc not impossible, just tricky).

Dokku user for a decade here, congrats on shipping, love to see more self-hosted PaaS options like this.

Why are binaries checked into the bin/ directory in the repo?

Compared to Dokku, I like how your LE support is builtin instead of a plugin. Is your main www ingress server an nginx that gets externally configured (like Dokku) or are you using net/http or libcaddy directly?

Dokku has a history of trying to compete with Heroku buildpacks - as a non Heroku/non Ruby developer this never resonated with me and there are a lot of vestigal parts (e.g. .web.1) that i would just put in my own Dockerfile directly. So focusing solely on Dockerfiles i personally feel is a good move.

One issue i faced with Dokku is eventually the build process for my Dockerized app was too memory-intensive to run on the VPS. I switched to running docker build locally, sending the container via `docker export | ssh | docker import`, and having a single `FROM myapp` dockerfile in Dokku. This was not particularly ergonomic to set up. Is it possible you can improve the UX of client-side built containers, or will you focus solely on the GitOps deploy?

Gratz on shipping! I've been eyeing Canine for my next Hetzner setup, but the database support on Mist is a nice feature.

Looks like I have some experiments to run soon.
