一、NAT(默认)
NAT网络模型，默认情况下，均为NAT模式，如网络的端口映射就为NAT
二、None(无网络)
[root@docker ~]# docker run --rm -ti --net=none centos:centos7
三、Host(与主机相同IP)
[root@docker ~]# docker run --rm -ti --net=Host centos:centos7
[root@docker /]# ifconfig
docker0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

四、联合网络（即两个容器共用一个IP地址）
