The very first problem I met is:

❯ kubebuilder create api --version v1beta1 --kind ServiceL2Status --group metallb.io
Error: failed to create API: unable to load configuration file: 
unable to load the configuration: 
unable to read "PROJECT" file: open PROJECT: no such file or directory

On the other hand, it seems not possible to init a kubebuilder project based on a non empty folder.

❯ kubebuilder init --domain metallb.io
Error: failed to initialize project: unable to run pre-scaffold tasks of "base.go.kubebuilder.io/v4": 
target directory is not empty (only go.mod, go.sum, files and directories with the prefix ".", 
files with the suffix ".md" or capitalized files name are allowed); found existing file "api"

So now there seems no way to generate the xxx_type.go ? I wonder how was the xxx_types.go written before?

I honestly don't remember how it was done (and I did it). The thing is, metallb is kind of a frankenstein that started before kubebuilder (or controller runtime) was a thing. Lately, we introduced CRDs and the controller-runtime based controllers in place of the existing configmap.

If I were you, I'd just copy one existing file and adjust it, doesn't seem a big deal.

@lwabish did you manage to sort it out?

I think so. I have finished coding and start working on testing them.
