There is also https://skateco.github.io/ which (at quick glance) seems similar

Skate author here: please try it out! I haven’t gotten round to diving deep into uncloud yet, but I think maybe the two projects differ in that skate has no control plane; the cli is the control plane.

I built skate out of that exact desire to have a dokku like experience that was multi host and used a standard deployment configuration syntax ( k8s manifests ).
