Description
Installing the chart in a cluster that doesn't use WorkerResourceTemplate leaves the manager pod in CreateContainerConfigError or CrashLoopBackOff:
open /tmp/k8s-webhook-server/serving-certs/tls.crt: no such file or directory
This happens even when I pass:
--set certmanager.install=false
--set certmanager.enabled=false
--set webhook.enabled=false
What I had to do to get it running:
Created a throwaway self-signed cert manually before installing the chart. Nothing in my cluster actually calls the WRT webhook, the cert just exists so the binary will boot.

Research direction
Reproduce the installation with certmanager and webhook disabled, then trace the manager pod startup and Helm chart values involved in creating the webhook server. Confirm the fix by verifying that a cluster without WorkerResourceTemplate can start the controller without a TLS secret and without entering CreateContainerConfigError or CrashLoopBackOff.
