部署网络插件

kubectl 检查这个节点上各个系统 Pod 的状态，其中，kube-system 是 Kubernetes 项目预留的系统 Pod 的工作空间（Namepsace，注意它并不是 Linux Namespace，它只是 Kubernetes 划分不同工作空间的单位）
[root@dock01 ~]# kubectl get pods -n kube-system

部署网络插件在 Kubernetes 项目“一切皆容器”的设计理念指导下，部署网络插件非常简单，只需要执行一句 kubectl apply 指令，以 Weave 为例：
kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
[root@dock01 ~]# kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
