security-profiles-operator: AppArmor does not work
As AppArmor not in GA so not sure if it is BUG or feature request
What happened:
AppArmor does not work on AKS per the steps in installation manual. I have tested this on vanilla Kubernetes 1.28.2 and AKS 1.27.3
What you expected to happen:
Expect AppArmor in effect
How to reproduce it (as minimally and precisely as possible):
kubectl -nsecurity-profiles-operator patch spod spod --type=merge -p='{"spec":{"webhookOptions":[{"name":"binding.spo.io","namespaceSelector":{"matchExpressions":[{"key":"control-plane","operator":"DoesNotExist"}]}},{"name":"recording.spo.io","namespaceSelector":{"matchExpressions":[{"key":"control-plane","operator":"DoesNotExist"}]}}]}}'
kubectl -n security-profiles-operator patch spod spod --type=merge -p '{"spec":{"verbosity":1}}'
kubectl -n security-profiles-operator patch spod spod --type=merge -p '{"spec":{"enableAppArmor":true}}'
