As of Kubespray 2.18.0, containerd is already the default container engine. If you have the chance, it is advisable and safer to reset and redeploy the entire cluster with a new container engine.

## System upgrade
If you want to upgrade the APT or YUM packages while the nodes are cordoned, you can use:
```ShellSession
ansible-playbook upgrade-cluster.yml -b -i inventory/sample/hosts.ini -e system_upgrade=true
```
Nodes will be rebooted when there are package upgrades (`system_upgrade_reboot: on-upgrade`).
This can be changed to `always` or `never`.
Note: Downloads will happen twice unless `system_upgrade_reboot` is `never`.
