Kubernetes From Scratch (Part 2)

Kubernetes without Minikube or MicroK8s

In my article in this series, “Kubernetes from Scratch,” I discussed a minimal Kubernetes system. Now I’d like to add to that success by making it a more complete system.

If you get Kubernetes from a cloud provider, things like storage and Ingress are most likely provided. The core Kubernetes system doesn’t provide things like Ingress, as that’s something that should integrate closely with the cloud system it’s running on.

To follow along, you should have read “Kubernetes from Scratch” and built up the system described. The system we built is four nodes running in VMs on a bare-metal server. As long as you have a similar setup, you should be able to follow along with minor adjustments. The cluster nodes are named kube1kube2kube3, and kube4. The kube1 node is the master, and the rest are workers. The main host is called beast and is running Ubuntu 20.04, and the VMs are running Ubuntu 18.04.

Also required for the second half of this article is a storage server we built in my article “Build Your Own In-Home Cloud Storage.” That server is running Ubuntu 20.04 on bare metal and has GlusterFS installed.
