I'm aware of these products, but do not fit my use case. I need to run some services on premises and have set up a self hosted Kubernetes instance on a physical server in a rack. It could be overkill and maybe I could use something like Docker Swarm. Apart from this I am unsure what I can use that isn't K8s to orchestrate my containers on site.
