Plugin shell execute on: role=master, but execute on all node

[init-object]

What happened:

在master机器上修改kube-apiserver.yaml 文件 调整nodeport范围
在node机器上也执行了shell脚本

What you expected to happen:

只在master节点上执行shell脚本

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

If you want to define your own apiserver config, The better way is using constomized kubeadm config. #762 check this out.

I try to use the apiserver config defined by myself but it doesn't take effect

I know the reason, because the sealer machine and the k8s-master0 machine are not the same machine. the rootfs folder is not mounted on the machine where the sealer is executed
I think this is a bug
