Controlling Kopf Operator Behavior to Prevent Unwanted Object Creation about kopf HOT 8 OPEN

The on.create() handlers are reacting to the creation of the resource, so any failure in the handler cannot prevent the creation that already happened.

If you want to be able to block the creation of the CR you can use a validating webhook which can reject the creation request if your criteria are/are not met. See: https://kopf.readthedocs.io/en/stable/admission/#validation-handlers

Hello again, I am struggling to use the admission controller in Kopf. I was using Kind and then switched to Minikube. I have been following the documentation, but it's not working, and I am encountering some unusual errors. I would be very grateful if you could provide any assistance regarding this.

I have even tried the webhookMinikube method, but it didn't work either.

It looks like the Windows signal interface is not compatible - you might want to try Linux.

My friend is using Windows WSL, but he is also facing some errors, and it's a bit ambiguous to set up the admission controller. @bobh66, have you ever used it? If so, could you please share the steps you have followed?

This is how I configure the admission webhook:

@kopf.on.startup()
async def configure(
    settings: kopf.OperatorSettings, logger: kopf.Logger, memo: kopf.Memo, **_
):
    addr = socket.gethostbyname(socket.gethostname())
    with socket.socket() as s:
        s.bind(("", 0))  # Bind to a free port provided by the host.
        port = s.getsockname()[1]
    settings.admission.server = kopf.WebhookServer(port=port, addr=addr)
    settings.admission.managed = "auto.kopf.dev"

Thank you for your response, but unfortunately the same problem always.
