Environment Build - Testing

• Download and run Vagrantfile from bmuschko's CKA Crash Course here.
  
• Initialize Kubernetes using these steps
  
• Set Kubelet IP addresses for each node (plan, worker1, worker2):
  

sudo vi /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

Add:

Environment="KUBELET_EXTRA_ARGS=--node-ip=xx.xx.xx.xx"

Then:

sudo systemctl daemon-reload
sudo systemctl restart kubelet

When all are set, go to COntrol Plane node and run:
kubectl get nodes -o wide
