安装kubemark

参考：https://github.com/kubernetes/community/tree/master/contributors/devel/sig-scalability

• 1 下载源码编译镜像（也可以用先有的）

# kubemark 镜像
staging-k8s.gcr.io/kubemark  # 下载源码编译之后
ss104301/kubemark          # 官方现有 

• 2 create hollow node
  kubectl create ns kubemark
kubectl create secret generic kubeconfig --type=Opaque --namespace=kubemark --from-file=kubelet.kubeconfig=/root/.kube/config --from-file=kubeproxy.kubeconfig=/root/.kube/config
  修改副本数
  kubectl scale rc hollow-node --replicas=1 -n kubemark
