How much does this course depend on kubeadm

Section 3.8 on Installing with kubeadm seems like somebody's working notes.  It refers you to the kubernetes web site for setting up a cluster with kubeadm.  That section refers you elsewhere for installing kubeadm, but the instructions for installing kubeadm on Ubuntu are just wrong.

I was able to get kubeadm installed, but the installation page says something about kubectl running in a crash loop waiting for kubeadm ???  But I see no kubectl process running.

Section 3.8 says to Run kubeadm init on the head node.  What is a head node?  Am I supposed to be running kubeadm on my laptop or was I supposed to set up a VM in the Google cloud to be the head node?

What is going on here?

Chapter 3 talks about the many different ways one can use to install Kubernetes (such as using GKE, Minikube, kubeadm, etc.), and then it goes in detail, step-by-step, through the installation process in lab 3.1.

Hi, Lab 3.1 gives step by step instruction on updating your master (head) node - your first Ubuntu VM, installing Docker and Kubernetes, initializing your cluster with kubeadm, and a few post-install verification steps. Lab 3.2 starts by giving step by step instructions on updating your worker node - your second Ubuntu VM, installing Docker and Kubernetes, adding the worker node to the cluster with kubeadm, and then it walks you thru your first nginx deployment on the cluster. 

I do not remember having any issues when I setup my cluster following these instructions in labs 3.1 and 3.2.

Good luck!
