Update

SimpleK8s

SimpleK8s is delivered as a single file, typically located in /boot/simplek8s/. To update to a new version, you can directly download it from the official download page.

A more convenient alternative is to use the simplek8s-update command for upgrading SimpleK8s:

$ # By default, simplek8s-update will upgrades from the stable channel.
$ simplek8s-update update

Upgrade third-party programs

Now is an opportune time to upgrade third-party programs, such as Kubernetes. You can temporarily stop these third-party programs and remove them, as they will redeployed upon the next reboot.

Please be cautious!

If you have custom third-party programs in /usr/local/bin, the next command will remove all of then! Alternatively you can manually remove each one.

$ # The next command will stop all Kubernetes components
$ stop-k8s

$ # Third-party files will be restored from factory on reboot
$ rm /usr/local/bin/* /usr/local/sbin/runc /opt/cni/bin/*

$ # Reboot your system to activate the new version:
$ reboot

And you are done!
