Hi Team,
Background
- Rancher version: v2.2.4, Helm: v2.10.0-rancher11, Host: v0.15.0-rancher8-1
- we have deployed rancher for managing all K8S nodes, and all nodes are managed by rancher.
- we’re going to upgrade K8S to the latest version, and rancher will control the whole process of upgrade, seems that there are lots of risks when upgrading.
So , the question is that:
- is there any way to uninstall rancher before upgrading K8S? If so , we can upgrade K8S nodes manually using kubeadm.
- in other words, don’t need to uninstall Rancher, we can upgrade K8S to the new version manually.
