# Updating k3s
|
||
|
|
|
||
|
|
## Before you start!
|
||
|
|
|
||
|
|
Ensure you back up your k3s cluster. This is particularly important if you use
|
||
|
|
an external datastore or embedded Etcd. Please refer to the below guide to
|
||
|
|
backing up your k3s datastore:
|
||
|
|
|
||
|
|
https://rancher.com/docs/k3s/latest/en/backup-restore/
|
||
|
|
|
||
|
|
Also, check your volume backups are also working!
|
||
|
|
|
||
|
|
## Proceedure
|
||
|
|
|
||
|
|
### Updates using Ansible
|
||
|
|
|
||
|
|
To update via Ansible, set `k3s_release_version` to the target version you wish
|
||
|
|
to go to. For example, from your `v1.19.3+k3s1` playbook:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
---
|
||
|
|
# BEFORE
|
||
|
|
|
||
|
|
- name: Provision k3s cluster
|
||
|
|
hosts: k3s_cluster
|
||
|
|
roles:
|
||
|
|
- name: xanmanning.k3s
|
||
|
|
vars:
|
||
|
|
k3s_release_version: v1.19.3+k3s1
|
||
|
|
```
|
||
|
|
|
||
|
|
Updating to `v1.20.2+k3s1`:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
---
|
||
|
|
# AFTER
|
||
|
|
|
||
|
|
- name: Provision k3s cluster
|
||
|
|
hosts: k3s_cluster
|
||
|
|
roles:
|
||
|
|
- name: xanmanning.k3s
|
||
|
|
vars:
|
||
|
|
k3s_release_version: v1.20.2+k3s1
|
||
|
|
```
|
||
|
|
|
||
|
|
### Automatic updates
|
||
|
|
|
||
|
|
For automatic updates, consider installing Rancher's
|
||
|
|
[system-upgrade-controller](https://rancher.com/docs/k3s/latest/en/upgrades/automated/)
|
||
|
|
|
||
|
|
**Please note**, to be able to update using the system-upgrade-controller you
|
||
|
|
will need to set `k3s_install_hard_links` to `true`.
