how to run production grade kubernetes on prem?
So, if you're interested on continuing CoreOS, tectonic and matchbox gets you CoreOS on-prem (@dghubble is a great resource). If you're looking at Ubuntu as an OS, I'd recommend MAAS and conjure-up.
Very well summarized discussion on different options: https://www.reddit.com/r/kubernetes/comments/720yg7/tools_to_deploy_k8s_onpremise_on_top_of_ubuntu/
Use conjure-up to run k8s on Ubuntu 16.04 VM; Kubernetes on Ubuntu VMs
- Ubuntu Server 16.04.3 LTS
