# Upgrade
|
||
|
|
|
||
|
|
# Command line
|
||
|
|
|
||
|
|
You can also use the `rancherd upgrade` command on a `server` node to automatically
|
||
|
|
upgrade RancherOS, Rancher, and/or Kubernetes.
|
||
|
|
|
||
|
|
# Kubernetes API
|
||
|
|
|
||
|
|
All components in RancherOS are managed using Kubernetes. Below is how
|
||
|
|
to use Kubernetes approaches to upgrade the components.
|
||
|
|
|
||
|
|
## RancherOS
|
||
|
|
|
||
|
|
RancherOS is upgraded with the RancherOS operator. Refer to the
|
||
|
|
[RancherOS Operator](./operator.md) documentation for complete information, but the
|
||
|
|
TL;DR is
|
||
|
|
|
||
|
|
```bash
|
||
|
|
kubectl edit -n fleet-local defautl-os-image
|
||
|
|
```
|
||
|
|
```yaml
|
||
|
|
apiVersion: rancheros.cattle.io/v1
|
||
|
|
kind: ManagedOSImage
|
||
|
|
metadata:
|
||
|
|
name: default-os-image
|
||
|
|
namespace: fleet-local
|
||
|
|
spec:
|
||
|
|
# Set to the new RancherOS version you would like to upgrade to
|
||
|
|
osImage: rancher/os2:v0.0.0
|
||
|
|
```
|
||
|
|
|
||
|
|
## rancherd
|
||
|
|
|
||
|
|
Rancherd itself doesn't need to be upgraded. It is only ran once per node
|
||
|
|
to bootstrap the system and then after that provides no value. Rancherd is
|
||
|
|
packaged in the OS image so newer versions of Rancherd will come with newer
|
||
|
|
versions of RancherOS.
|
||
|
|
|
||
|
|
## Rancher
|
||
|
|
Rancher is installed as a helm chart following the standard procedure. You can upgrade
|
||
|
|
Rancher with the standard procedure documented at
|
||
|
|
https://rancher.com/docs/rancher/v2.6/en/installation/install-rancher-on-k8s/upgrades/.
|
||
|
|
|
||
|
|
## Kubernetes
|
||
|
|
To upgrade Kubernetes you will use Rancher to orchestrate the upgrade. This is a matter of changing
|
||
|
|
the Kubernetes version on the `fleet-local/local` `Cluster` in the `provisioning.cattle.io/v1`
|
||
|
|
apiVersion. For example
|
||
|
|
|
||
|
|
```shell
|
||
|
|
kubectl edit clusters.provisioning.cattle.io -n fleet-local local
|
||
|
|
```
|
||
|
|
```yaml
|
||
|
|
apiVersion: provisioning.cattle.io/v1
|
||
|
|
kind: Cluster
|
||
|
|
metadata:
|
||
|
|
name: local
|
||
|
|
namespace: fleet-local
|
||
|
|
spec:
|
||
|
|
# Change to new valid k8s version, >= 1.21
|
||
|
|
# Valid versions are
|
||
|
|
# k3s: curl -sL https://raw.githubusercontent.com/rancher/kontainer-driver-metadata/release-v2.6/data/data.json | jq -r '.k3s.releases[].version'
|
||
|
|
# RKE2: curl -sL https://raw.githubusercontent.com/rancher/kontainer-driver-metadata/release-v2.6/data/data.json | jq -r '.rke2.releases[].version'
|
||
|
|
kubernetesVersion: v1.21.4+k3s1
|
||
|
|
```
|
