Build a Kubernetes Home Lab from Scratch step-by-step!
Building a Kubernetes Home Lab environment from scratch might seem like a daunting task. However, it is actually pretty straightforward with the right tools in place. In this video, we are going to use Kubeadm to initialize a Kubernetes cluster from scratch in our home lab environment. Using Kubeadm takes some of the heavy lifting out of the underlying complexities of Kubernetes. We look at how to build the Kubernetes home lab cluster from scratch step-by-step. Join me in the adventure!

Installing kubeadm, kubelet, kubectl, and Kubernetes - 5:02
Explaining why we are only running commands on the Kubernetes master node - 5:16
Running the kubeadm init command - 6:00
kubeadm init command finishes successfully and have the kubeadm join command - 6:20
The worker nodes are now caught up with the master node - 6:58
We still have the special join command to copy and paste into our worker nodes - 7:20
Notice the output of workers. They have successfully joined the Kubernetes cluster - 7:45
Kubectl commands are failing. This is because we haven't copied our kubeconfig to our HOME directory - 7:54
Nodes are in the not ready state. This is because we haven't deployed container networking - 8:30
We are going to deploy Calico for container networking - 8:45
After container networking we check the STATE of our Kubernetes nodes - 9:16
