$ microk8s add-node
From the node you wish to join to this cluster, run the following:
microk8s join 10.0.2.15:25000/136ac2967078d5490de2d1a2d3a8bf52
 
If the node you are adding is not reachable through the default interface you can use one of the following:
 microk8s join 10.0.2.15:25000/136ac2967078d5490de2d1a2d3a8bf52
 microk8s join 192.168.0.40:25000/136ac2967078d5490de2d1a2d3a8bf52
