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]:liyongjian5179/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!
