Running the tutorial locally fails due to webhook certs

Following the kubebuilder book tutorial, I am facing an issue when running the controller locally by disabling the webhooks.

make run ENABLE_WEBHOOKS=false

as described in the documentation: https://book.kubebuilder.io/cronjob-tutorial/running.html#running-webhooks-locally

Got this error:

1.6535567690158641e+09  ERROR   setup   problem running manager {"error": "open /var/folders/gn/jhjjkq191nl3ggqp77qsc1pr0000gn/T/k8s-webhook-server/serving-certs/tls.crt: no such file or directory"}

It looks like the environment variable is ignored.

I got same error too.
My kubebuilder version is as followed
Version: main.version{KubeBuilderVersion:"3.6.0", KubernetesVendor:"1.24.1", GitCommit:"f20414648f1851ae97997f4a5f8eb4329f450f6d", BuildDate:"2022-08-03T11:47:17Z", GoOs:"darwin", GoArch:"amd64"}

if os.Getenv("ENABLE_WEBHOOKS") != "false" {
        if err = (&batchv1.CronJob{}).SetupWebhookWithManager(mgr); err != nil {
            setupLog.Error(err, "unable to create webhook", "webhook", "CronJob")
            os.Exit(1)
        }
    }

this statement in main.go should recover this normally.

Hi @jakobmoellersap and @zamonia500,

Technically, the webhooks can be run locally, but for it to work you need to generate certificates for the webhook server and store them at /tmp/k8s-webhook-server/serving-certs/tls.{crt,key}. For more details about running webhook locally, refer here.

Then, to disable this one we need to ensure that we have the ENV VAR exported in the same place where you will execute the make run.

Did you tried :

export ENABLE_WEBHOOKS=false
make run

To see if that works?

Also, I think the fix here is only to update the docs with the above instructions.
Can you check it out and would you like to contribute to the project by opening a PR so we can fix it?
