#KUBEADM CENTOS 7 KUBE PROXY IPVS HOW TO#
I found several articles on how to do this but somehow I got off track a few times and thought another blog post with step by step instructions and screenshots would help others. Therefore, I set out to deploy k8s in my vSphere home lab on some CentOS 7 virtual machines using Kubeadm. Also, from a learning perspective, there is no greater way to learn the underpinnings of a solution than having to deploy and manage it on your own. While these hosted solutions provide additional features such as the ability to spin up a load balancer, they also cost money every hour they’re available and I’m planning on leaving my cluster running.
