I run microk8s on a 3 node cluster, using FluxCD to deploy and manage my services. I also work with Kubernetes at work, so I’m very familiar with the concepts. But I will never use anything else.
If you want maximum control and flexibility, learn Kubernetes. For a lot of people (myself included) it’s overkill, but IMO it’s the best.
My main gripe with docker-compose, which is what I used to use, is that service changes require access to the machine. I have to run commands on the host to alter services. With Kubernetes, and more precisely a GitOps model, you can just make a commit to a git repo and it will roll out.
