What ansible-kubeadm can do:
- Install kubeadm on a variety of linux distribution
- lock kubeadm package to avoid upgrade
- init a cluster and join node in a idempotent manner
- upgrade a cluster in an indempotent maner (just add +1 to minor version config and your good to go !)
What ansible-kubeadm expect to be done and will not do:
- Upgrading distro
- Upgrade the kernel
- install ntp
- installing docker (or whatever CRI)
- disable swap
- remove unattented-upgrade
- configure CNI
