问题
So I was following along this tutorial (https://www.youtube.com/watch?v=KBTXBUVNF2I) and after setting up the reconciler, when I execute "make run", I am getting the following error:

The error seems to originate from this line:
https://github.com/DirectXMan12/kubebuilder-workshops/blob/605890232fb368a8ff00ac5e9879c8dfd90f904c/controllers/redis_controller.go#L73
Any Idea what might be causing this error and how to solve it?
回答1:
That is using a relatively new feature, make sure your kubernetes is very up to date and has server side apply enabled.
