1.calico node 容器在kubernetes中以DaemonSet 的方式运行，容器的网络模式为hostNetwor，与host共享网络栈，拥有相同的Ip和hostname
2.查看某个pod：[root@bserver40 ~]# kubectl get pods -o wide -n kube-system |grep -i tiller
tiller-deploy-5dfffddb8d-n4vp6 1/1 Running 0 3d 10.233.122.4 bserver42
3.查看某个pod的网卡和ip
先用calicoctl查看容器A的workloadEndpoint： --workload=<namespace>.<podname>
[root@bserver40 ~]# calicoctl get workloadendpoint --workload=kube-system.tiller-deploy-5dfffddb8d-n4vp6 -o yaml
- apiVersion: v1
kind: workloadEndpoint
node: bserver42
workload: kube-system.tiller-deploy-5dfffddb8d-n4vp6

用一个例子来演示会更加清晰
