Answer 1

I did use below URL for deploy three node cluster. https://blog.alexellis.io/kubernetes-in-10-minutes/

Note: if you want to start only single node cluster, then run taint command as per describe in above URL on master node so container can launch on master node also and if you want to run worker node separately then launch separate vm/vms and run command from start to till swapoff command then join vm to master.

I think you have missed a step in this link .

You seem to have not created a Pod network Add-on , create a local pod network such as flannel etc.
