Client-server version difference exceeds supported skew (+/-1)

[Andriy_S]

Version difference between the client (1.xx) and the server (1.xx) exceeds the supported minor version skew of +/-1

Sometimes during the upgrade process, you can see such a warning:

This means that kubectl version installed on the server differs by more than 1  version from Kubernetes, which is not officially supported.

To fix this issue, you’ll need to set the following value in the configuration yaml file:

update_k8s_version: true

And run the update as usual
