v=$(oc -n openshift-kube-apiserver get configmap config -o jsonpath='{.data.config\.yaml}') || exit 1
if printf '%s' "$v" | grep -Eq '"kubelet-read-only-port":[[:space:]]*\[[[:space:]]*"0"[[:space:]]*\]'; then echo compliant; else echo noncompliant; fi

修复方式

修复方法: 操作指南或基础设施补丁

In earlier versions of OpenShift 4, the read-only-port argument is not used. Follow the instructions in the documentation to create a kubeletconfig CRD and set the kubelet-read-only-port is set to 0.
