Get client.Client in webhook admission

[FillZpp]

Now i create webhook admission using kubebuilder alpha webhook ..., and then find the webhook
handler generated like this:

type MyResourceCreateUpdateHandler struct {
	// Client  client.Client

	// Decoder decodes objects
	Decoder types.Decoder
}

The Client which i need in webhook validating or mutating has been commented.
How could i get client or informer in webhook admission?

This is a documentation issue. I will update it.

I will use the test project as an example to show you how to use a client:

1. Define a client by uncommenting https://github.com/kubernetes-sigs/kubebuilder/blob/master/test/project/pkg/webhook/default_server/frigate/validating/frigate_update_handler.go#L39
2. Enable the injection by uncommenting https://github.com/kubernetes-sigs/kubebuilder/blob/master/test/project/pkg/webhook/default_server/frigate/validating/frigate_update_handler.go#L68-L74
3. Add "sigs.k8s.io/controller-runtime/pkg/client" in the import section.
4. If the [import path] for your API type is not in the default path, adjust it. This scenario happens when the API is defined out of tree.

Thanks a lot @mengqiy
I never noticed (2) before.

When I run the following command.
kubebuilder alpha webhook --group core --version v1 --kind Pod --type=mutating --operations=create,update

I get the following error :

make: *** [vet] Error 2```
Seems like webhook.go was not generated 
This only happens when the git repo is the same has other controllers created using kubebuilder as well. 
We have one git repo where we share controllers.

@mohnishkodnani I guess the project was created by an older kubebuilder that doesn't support scaffolding webhook. It currently assume webhook.go was generated at kubebuilder init step, which may not be always true.
