## Automatic upgrade ## Automatic upgrade
By default, k3os and its embedded k3s instance get upgraded automatically on each node, thanks to its embedded system upgrade controller. By default, MicroOS and its embedded k3s instance get upgraded automatically on each node, and reboot safely via [Kured](https://github.com/weaveworks/kured) installed in the cluster.
_You can also choose to automatically kustomize the Hetzner CCM and CSI to set their container images to "latest" with an imagePullPolicy of "Always". That means that when the nodes upgrade, these container images will be automatically upgraded too. For more info on this, see [terraform.tfvars.example](terraform.tfvars.example)._ _You can also choose to automatically kustomize the Hetzner CCM and CSI to set their container images to "latest" with an imagePullPolicy of "Always".

_If you wish to turn off automatic upgrade on a specific node, you need to take out the label `k3os.io/upgrade=latest`. It can be done with the following command:_ _About [Kured](https://github.com/weaveworks/kured), it does not have a latest tag present of its image, but it's pretty compatible, so you can just manually update the tag from once every year or more._
_Last but not least, if you wish to turn off automatic upgrade on a specific node, you need to ssh into it and issue the following command:_
```sh ```sh
kubectl label node <nodename> 'k3os.io/upgrade'- systemctl --now disable transactional-update.timer
``` ```
