MicroK8S adding new node

i was installing sysmtem by following guide

On mks1 and mks2 run

echo 192.168.5.114 mks3 | sudo tee -a /etc/hosts

Then, on master node

microk8s add-node

As result it prints:

microk8s join 192.168.5.107:25000/AgkdIMSZBoUOcbkdFxPfYfEXUIkgoatk

which i run on new node

After that kubectl get nodes shown all three nodes (i waited half of minute, it did not appear immediatelly)

Thats all, third node is added, now, we need to make rolling reboot

On a second node did:

sudo apt-get update
sudo apt-get upgrade
sudo reboot

After reboot, waited until kubectl get nodes shown all nodes and five more minutes just in case for all workloads to spinup

While waiting you may want to run

kubectl get pods -o wide --all-namespaces

or even

kubectl get pods -o wide --all-namespaces -w

To watch how pods are moving
