>I think there is a real hole in the market for a simple solution that lets you deploy some containers to some instances in a declarative fashion without all of that complexity

That's how I see it as well but it's really tough to go against the grain. I have a small enthusiastic community of users around Uncloud (https://github.com/psviderski/uncloud) who went full circle - fed up with k8s and came back to simple, boring declarative Compose deployments across a handful of interconnected hosts.

Uncloud is essentially a cluster version of Docker Compose without a control plane and cluster management overhead.
