start at

https://kubernetes.io/docs/setup/

we will come back to the learning section

https://kubernetes.io/docs/tasks/tools/

We go directly to "installing kubeadm" in the production section

https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/

Check prerequisites

https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/#verify-mac-address

MAC addresses are different - if VMs were independently created.

checking ports

ubuntu@ubuntu01:~$ nc 127.0.0.1 6443 -v
nc: connect to 127.0.0.1 port 6443 (tcp) failed: Connection refused

check ports later on a running server

disable swap

ubuntu@ubuntu01:~$ cat /proc/swaps

# that works even if disks are added and removed. See fstab(5).
