You will start a two node cluster on your machine, one master and one worker. For this you need to install VirtualBox and vagrant, then:

git clone [email protected]:wuestkamp/cka-example-environments.git
cd cka-example-environments/cluster1
./up.sh

vagrant ssh cluster1-master1
vagrant@cluster1-master1:~$ sudo -i
root@cluster1-master1:~# kubectl get node

You should be connected as root@cluster1-master1. You can connect to other worker nodes using root, like ssh root@cluster1-worker1 If you want to destroy the environment again run ./down.sh. You should destroy the environment after usage so no more resources are used!
