        Docker容器有哪几种网络模型?针对这个问题,今天小编总结这篇有关Docker网络模型的文章,希望能帮助更多想解决这个问题的朋友找到更加简单易行的办法。
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格式:docker run --net=none
[root@docker ~]# docker run --rm -ti --net=none centos:centos7格式:docker run --net=host
[root@docker ~]# docker run --rm -ti --net=Host centos:centos7
[root@docker /]# ifconfig
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.7.5.1  netmask 255.255.255.0  broadcast 172.7.5.255
        inet6 fe80::42:28ff:fe56:8b6  prefixlen 64  scopeid 0x20<link>

第一个容器运行
