+description: Install the system-upgrade-controller
+---
+
+To upgrade Kairos with Kubernetes, it is necessary to have [system-upgrade-controller](https://github.com/rancher/system-upgrade-controller) deployed on the target cluster.
+
+[The upstream documentation](https://github.com/rancher/system-upgrade-controller#deploying) on how to install the system-upgrade-controller, is this command:
+
+```
+kubectl apply -k github.com/rancher/system-upgrade-controller
+```
+
+This command requires the `git` command to be available in order to clone the remote repository. Kairos images, generally, don't include git. You will need to run this command from a machine which has `git` available and access to the cluster with a valid KUBECONFIG file.
+
+Alternatively, from withing the Kairos node, you can deploy the following `Job` which will clone the system-upgrade controller repository to the `/home/kairos` directory:
+
+```
+apiVersion: batch/v1
+kind: Job
+metadata:
+  name: git
+spec:
+  template:
+    spec:
+      restartPolicy: Never
+      containers:
+        - name: git
+          image: alpine/git
+          command: ["git", "clone", "--branch", "{{< system-upgrade-controller-version >}}", "https://github.com/rancher/system-upgrade-controller", "/homedir/system-upgrade-controller"]
+          volumeMounts:
+            - name: homedir
+              mountPath: /homedir
+      volumes:
+        - name: homedir
+          hostPath:
+            path: /home/kairos
+            type: Directory
+```
+
+(make sure you checkout the desired branch/release)
+
+Then, from the `/home/kairos` directory, you can run this command to deploy the system-upgrade-controller:
+
+```
+kubectl apply -k system-upgrade-controller
+```

 #### Upgrades with Kubernetes
 
-Kairos can be upgraded with the [system-upgrade-controller](https://github.com/rancher/system-upgrade-controller) from
-Kubernetes itself. The controller and all the relevant CRDs [should already be installed](https://github.com/rancher/system-upgrade-controller?tab=readme-ov-file#deploying)
-(at the time of writing, this workaround is needed in order to install the system-upgrade-controller: [workaround for the missing "latest" tag](https://github.com/rancher/system-upgrade-controller/issues/302#issuecomment-2027163863)).
+To upgrade Kairos with Kubernetes, system-upgrade-controller needs to be deployed on the target cluster. [Read the instructions here]({{< relref "./system-upgrade-controller" >}}).
 
 A "Plan" resource needs to be created which will use the image generated in the step above.
 Since that image only contains the EFI files for the upgrade and in order to be able use any ImagePullSecrets
