I worked on the lab of “Cluster Upgrade Process”, I tried to follow the instuctions from the official K8S docs, and they don’t work in the lab. And the solution for this lab is different also. How can you give to students such labs, if the instructions from real docs doesn’t work and match the right solution??? Crazy thing
Thanks for your feedback!
Could you please elaborate on what specifically is missing or differs from the official documentation?
It’ll make it easier for me to coordinate with the relevant team to investigate and address the issue.
It was " Lab - Cluster Upgrade Process". Task number 7. The solution for this lab is different from the solution from the official docs of K8S
I followed the lab solution, and it works.
If you could share what exactly differs in the docs, I can ask the team to review.
Yeah, from the solution everything works great. But commands from official docs are different
The standard docs are one way of doing things, but there’s a range of approaches that can also work. Since kubeadm installs have a lot of options, you should expect some range of approaches will be valid. While you probably won’t be tested on doing an install during an exam (it takes too long), you will likely need to be able to do the task in real life, and flexibility is how real life rolls 
I agree with you. The problem was, that the lecture before the lab doesn’t match the solution and the solution from official docs didn’t work in the lab
