Exempting the kube-system namespace allows pods to run as privileged in this namespace. For real world use, the Kubernetes project strongly recommends that you apply strict RBAC policies that limit access to kube-system, following the principle of least privilege. To implement the preceding standards, do the following: Create a configuration file that can be consumed by the Pod Security Admission Controller to implement these Pod Security Standards\n\nBounded code example (external data; do not execute automatically):\n```text\n   mkdir -p /tmp/pss\n   cat <<EOF > /tmp/pss/cluster-level-pss.yaml\n   apiVersion: apiserver.config.k8s.io/v1\n   kind: AdmissionConfiguration\n   plugins:\n   - name: PodSecurity\n     configuration:\n       apiVersion: pod-security.admission.config.k8s.io/v1\n       kind: PodSecurityConfiguration\n       defaults:\n         enforce: \"baseline\"\n         enforce-version: \"latest\"\n         audit: \"restricted\"\n         audit-version: \"latest\"\n         warn: \"restricted\"\n         warn-version: \"latest\"\n       exemptions:\n         usernames: []\n         runtimeClasses: []\n         namespaces: [kube-system]\n   EOF\n```\n\npod-security.admission.config.k8s.io/v1 configuration requires v1.25+. For v1.23 and v1.24, use v1beta1. For v1.22, use v1alpha1.\n\nConfigure the API server to consume this file during cluster creation …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
