Hi there is a section on in the , which has the content for upgrading Linux worker nodes. I wonder do you want a separate document for it?
Yes. This issue is a request for a document just like but with Linux in the title. It is OK to adapt existing pages and to link to them.
right, i can recall the section only says: From the Windows node, upgrade kubeadm: and no addition for another os. This will be helpful. are you working on it?
Thanks, for the information!
Hi thanks for your comments. Yeah, I am working on it. I will soon open a PR for it.
