Kyverno Version

1.12

Kubernetes Version

1.24

Kubernetes Platform

GKE

Description

In Kyverno version 1.12, I don't see any msg or note fields in Kyverno logs that need to be displayed when using the validate rule type. But in version 1.11 it is fully available.

My policy

apiVersion: kyverno.io/v1
kind: ClusterPolicy
metadata:
  name: slsa-verify-all-images
spec:
  validationFailureAction: Enforce

  background: true

        context:

            reference: "{{ element.image }}"
        deny:
          conditions:
            all:
              - key: '{{ imageData.registry || "" }}'
                operator: NotEquals
                value: gcr.io
              - key: '{{ imageData.resolvedImage || "" }}'

Manifest of my pod applied

apiVersion: v1
kind: Pod
metadata:
  name: taile-test-kyverno-pod
  namespace: default
  labels:
    app: taile-test-kyverno-pod
spec:
  containers:
  - name: taile
    image: python:alpine3.19
    tty: true

The error message I get from the console screen

Error from server: error when creating "STDIN": admission webhook "validate.kyverno.svc-fail" denied the request:

resource Pod/default/taile-test-kyverno-pod was blocked due to the following policies

slsa-verify-all-images:

    not been whitelisted ["python:alpine3.19"]'

Steps to reproduce

Upgrade kyverno version to v1.12 .
Apply My policy in above description .
Use kubectl to capture logs kubectl logs -f -l app.kubernetes.io/part-of=kyverno -n kyverno | grep "taile-test-kyverno-pod" (taile-test-kyverno-pod is my pod name) .
Apply Manifest of my pod .
Check logs get from step 3 .

Expected behavior

I would like the log information to be fully described as in v1.11, which I showed above.
