Impact

Protect tuned kernel parameters from overriding kubelet default kernel parameter values. Kernel parameters are usually tuned and hardened by the system administrators before putting the systems into production. These parameters protect the kernel and the system. Your kubelet kernel defaults that rely on such parameters should be appropriately set to match the desired secured system state. Ignoring this could potentially lead to running pods with undesired kernel behavior.

How to Fix

Kind: Pod [source,go]

{ "apiVersion: v1 kind: Pod metadata: creationTimestamp: null labels: component: kubelet tier: control-plane name: kubelet namespace: kube-system spec: containers:

• command:
• • kubelet
• • --protect-kernel-defaults=true image: gcr.io/google_containers/kubelet-amd64:v1.6.0 ...", }
