I upgraded rancher to 2.10.2 then ran into bug. No gui no kubectl working. How to downgrade rancher manually to 2.10.1 , I only have ssh access to all nodes. Thanks

in your helm command you can pass version information

The kubectl and helm list doesn't work.

hmm

How I get kubeconfig from control plane nodes ? it's rke1.

as per this doc: https://rke.docs.rancher.com/kubeconfig

When you deployed Kubernetes, a kubeconfig is automatically generated for your RKE cluster. This file is created and saved as kube_config_cluster.yml.

Couldn't find file on controlplane/workers nodes using

find / -name kube_config_cluster.yml

do you have

kube_config_rancher-cluster.yml

I have kubeconfig file on my workstation that I generated from rancher gui before the upgrade . This one is not working. On controlplane nodes, I can't find the initial kubeconfig that usually points to controlplance localhost.

was this cluster generated from Rancher UI? or from running

rke up

The initial cluster was created using terraform provider

rancher/rke

to create

resource "rke_cluster"

you may want to ask in #C896QJRPE I am not sure how you can retrieve kubeconfig if its not saved as

kube_config_cluster.yml

or

kube_config_rancher-cluster.yml

Thanks.
