If this is configurable today, why can't the user scan them now? I must be missing something.

it was impossible because specific Kind values were hard-coded in multiple places.
When the actual type didn’t match one of those hard-coded cases, the code returned an error.
for example:
https://github.com/aquasecurity/trivy-operator/blob/main/pkg/kube/object.go#L204-L237
https://github.com/aquasecurity/trivy-operator/blob/main/pkg/kube/object.go#L336-L385

Just thinking out loud how to test this change: As part of our integration tests, we can specify the new PV resource and have it get scanned and create reports based on that. WDYT?

simar7 · 2025-08-07T01:02:25Z

Another point about testing, I added perf support on a feature branch (to enable profiling) but I think I'll enhance it by adding support for it to be enabled with a configuration option. That we the performance team can test this branch to see if there's a big performance overhead or not.

I updated that PR here #2666

Pull Request Overview

This PR adds support for any kinds of resources in policy checks by implementing a new scope resolution system. It removes hardcoded resource type validation and introduces dynamic resource discovery based on the Kubernetes scheme.

Introduces a new K8sScope resolver for dynamic scope detection of Kubernetes resources
Replaces hardcoded resource lists with dynamic resource discovery in controllers
Adds support for PersistentVolume and PersistentVolumeClaim resources in configuration audits

 // security report.
 func ComputeSpecHash(obj client.Object) (string, error) {
-	switch t := obj.(type) {
+	switch obj.(type) {


The variable t is declared but no longer used after the switch statement change. Consider removing the unused variable declaration.

Adding PersistentVolume to the default target workloads should also include PersistentVolumeClaim for consistency, as both are tested in the integration tests.

Suggested change

TargetWorkloads string `env:"OPERATOR_TARGET_WORKLOADS" envDefault:"Pod,ReplicaSet,ReplicationController,StatefulSet,DaemonSet,CronJob,Job,PersistentVolume"`

TargetWorkloads string `env:"OPERATOR_TARGET_WORKLOADS" envDefault:"Pod,ReplicaSet,ReplicationController,StatefulSet,DaemonSet,CronJob,Job,PersistentVolume,PersistentVolumeClaim"`

 		})
+


Can we also add another case where we don't specify the scanning of a PVC but create one? In such a case the assertion should ensure that no report is generated.

Another case should be that we create a new resource (something other than what we support by default) it shouldn't generate any reports either.
