Как проверяется

Метод проверки: Команда оболочки

out=$(kubectl get pods -A -o go-template='{{range .items}}{{.metadata.namespace}} {{.metadata.name}} {{.spec.hostPID}}{{"\n"}}{{end}}') || exit 1
bad=$(printf '%s\n' "$out" | awk -v ex='^(kube-system|kube-public|kube-node-lease)$' 'NF && $1 !~ ex && ($3=="true")')
if [ -z "$bad" ]; then echo compliant; else printf '%s\n' "$bad" | head -n 25; fi

Ожидаемый вывод

compliant

Configure Pod Security Admission on workload namespaces so pods that request spec.hostPID: true are denied at admission time. In current EKS guidance, AWS recommends applying Pod Security Standards with at least the baseline profile cluster-wide and the restricted profile for workload namespaces. AWS also states that the baseline profile prohibits hostPID, while restricted inherits that restriction. For remediation, use enforce because AWS documents that only enforce rejects violating pods. warn and audit can help during rollout, but they do not block admission. • Label each workload namespace to enforce restricted. kubectl label ns NAMESPACE pod-security.kubernetes.io/enforce=restricted --overwrite • Add warn and audit during transition if you want visibility into violations before or alongside enforcement.
