A little OT, but is there anything remotely competitive with k8s these days? By "competitive", I mean: good feature set, thriving community, active development.

I still use Docker Swarm for small scale stuff, and am pretty happy with it - it's simple, easy to use and doesn't eat resources. But it very much feels like Docker have given up on it.

I'm particularly interested to know if there is anything simpler than k8s that's competitive?
