There was a problem hiding this comment.
I still believe that the internal networks need to be removed from the list in this specific case since it's totally valid on self-hosted (and even hosted) clusters:
- 10.0.0.0/8 (actually Kubernetes default)
- 172.16.0.0/12
- 192.168.0.0/16
- fc00::/7
- Run make manifests generate to sync pattern validations for localEndpoint and HashiCorp Vault baseURL into the CRD YAML - Remove unused eventReasonClusterLookupError and eventReasonClusterAuthError constants flagged by golangci-lint
