I have a single node rancher and a HA kubernets cluster. I install k8s with rancher rke.
My rancher version is 2.3.3, k8s version is 1.16.3.
Now,i have update my rancher to 2.3.5,and I want to upgrade k8s to 1.17.3.
Follow this https://rancher.com/docs/rancher/v2.x/en/cluster-admin/editing-clusters/#upgrading-kubernetes
I found i can’t edit the k8s version.
Thanks for your contribution!
