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
