Usually, we do not add log in this file, as you can see, no klog imported in this file, each function will be called repeatedly during each sync which will flood too many logs, what about adding descriptions in types.go to describe this behavior clearly.

@DanielZhangQD Thank you for your reply. Yes, I think it makes sense not to put the log in this file. But I suppose we can add an enum for kubebuilder in types.go to prevent invalid input. I updated the code in the latest commit.

This is not necessary, right？

Yes, if we use enum then this is not necessary. I have removed it in the latest commit.

Does this work if this field is not set explicitly?

@DanielZhangQD Do you mean we need a default value for this field? If so, what should be the default value?
If we want a default value when the field is not set explicitly, we can also specify the default value through this kubebuilder tag

What problem does this PR solve?
This PR solves the problem mentioned in #4649. Basically, we believe an invalid
podManagementPolicyshould not be silently replaced by some default values without explicitly telling the user that the input is invalid.What is changed and how does it work?
We added a warning to explicitly tell the user that
podManagementis invalid and the operator will useParallelinstead.Code changes
