Nodes or pods? You can execute on pods via kubectl exec. On nodes, I don't think there is any way. You just a daemonSet with hostpath or host network or something like that. But you usually don't want to just exec something. You want something self-healing and immutable pods. So, for pods you should consider build and deploy again, and for nodes a daemonSet that constantly run and checks all it needs and acts accordingly.
