1、POD设计,netshoot:latest作为sidecar，用于调试网络。
sdfp2-net.yaml设计
指定IP
annotations:
cni.projectcalico.org/ipAddrs: "[\"172.16.135.135\"]"
指定主机名称
hostname: sdfp2
containers:
- image: mi:v1
......
- image: nicolaka/netshoot:latest
# k apply -f sdfp2-net.yaml
[root@sdfp2 ~]# k get pod
NAME READY STATUS RESTARTS AGE
sdfp2-netshoot-dp-84f4d7b99d-5pvhm 2/2 Running 0 35m进入sdfp2容器运行服务进程
# k exec -ti sdfp2-netshoot-dp-84f4d7b99d-5pvhm -c sdfp2 -- bash
拷贝license.ini,mid.xml——>/home/cdatc/AirNet/config/gconf/mid/；network.xml——>/home/cdatc/AirNet/config/(也需更新mid.xml，否则提示授权问题)

top查看mnt\mid\afp\rfp正常运行进入sidecar容器查看组播172.16.135.135.50849 > 225.1.0.1.40002
