The policy will be applied to all namespaces in the cluster. It checks all newly created Pods that run any image matching the expression `docker.stackable.tech/*-operator:23.7.*` (all Stackable operators version 23.7.*) and ensures that these images have been signed by a Stackable Github Action from the release 23.7 (`https://github.com/stackabletech/*-operator/.github/workflows/build.yml@refs/tags/23.7.*`). If the signature of an operator image is invalid or missing, the policy will deny the pod creation.
The policy will be applied to all namespaces in the cluster. It checks all newly created Pods that run any image matching the expression `docker.stackable.tech/+++*+++-operator:23.7.+++*+++` (all Stackable operators version 23.7.+++*+++) and ensures that these images have been signed by a Stackable Github Action from the release 23.7 (`https://github.com/stackabletech/+++*+++-operator/.github/workflows/build.yml@refs/tags/23.7.+++*+++`). If the signature of an operator image is invalid or missing, the policy will deny the pod creation.
For a more detailed explanation of the policy options, please refer to the https://kyverno.io/docs/writing-policies/verify-images/sigstore/#keyless-signing-and-verification[Kyverno documentation].
If the `subject` field in the policy is changed to something like `https://github.com/test/*`, the policy will deny the creation of operator pods because the signature is no longer valid.
