I want upgrade my current rancher cluster. My cluster is now in version 2.1.1 and was created by rancher without rke tool.
|User Interface |v2.1.4|
I seems to me that I have to do this steps
- Do a full backup / snapshoot of the etcd
- Install tiller repo
- Update with catalog helm repository.
I am a little afraid because I think that my rancher not was deployed by helm and my cluster is not installed with RKE
Could someone confirm this?
