It sounds like Custom Tasks might also be our path to integrating with Tekton Triggers, which currently disallows triggered creation of any non-Tekton resources. However, Triggers _can_ create Custom Tasks...

Tekton uses [`knative/pkg`'s `webhook` package](https://github.com/knative/pkg/tree/master/webhook) to create and manage webhook certs, which has been helpful ([code here](https://github.com/tektoncd/pipeline/blob/master/cmd/webhook/main.go)). I honestly don't know much about how webhooks (certs especially) are configured for...

Someone shared this during the community call yesterday and I forgot who it was now (sorry!) but it seems useful: https://book.kubebuilder.io/cronjob-tutorial/webhook-implementation.html

Thanks for your response! I had imagined this being phrased as another type of parameterized BuildStrategy, but one that didn't require any source input, only an image to rebase. ```yaml...

I'd like to be really careful not to expand the scope of this to include triggering. That's a separate EP entirely, which should be designed in isolation in such a...
