Docker容器有哪几种网络模型

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。

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)

格式：docker run --net=none[root@docker ~]# docker run --rm -ti --net=none centos:centos7

三、Host(与主机相同IP)

格式：docker run --net=host[root@docker ~]# docker run --rm -ti --net=Host centos:centos7[root@docker /]# ifconfigdocker0: flags=4099  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        ether 02:42:28:56:08:b6  txqueuelen 0  (Ethernet)        RX packets 135990  bytes 9017234 (8.5 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 158771  bytes 317188403 (302.4 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0ens192: flags=4163  mtu 1500        inet 10.3.153.120  netmask 255.255.255.0  broadcast 10.3.153.255        inet6 fe80::36aa:b367:aa13:b475  prefixlen 64  scopeid 0x20        ether 00:50:56:9b:00:06  txqueuelen 1000  (Ethernet)        RX packets 747539  bytes 528246025 (503.7 MiB)        RX errors 0  dropped 1227  overruns 0  frame 0        TX packets 249250  bytes 38867074 (37.0 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10        loop  txqueuelen 1  (Local Loopback)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

四、联合网络（即两个容器共用一个IP地址）

第一个容器运行
-----
[root@docker ~]# docker run --rm -ti centos:centos7     #以nat模式启动了一个容器[root@2f504d6966dc /]# ifconfigeth0: flags=4163  mtu 1500        inet 172.7.5.2  netmask 255.255.255.0  broadcast 172.7.5.255     #IP172.7.5.2        ether 02:42:ac:07:05:02  txqueuelen 0  (Ethernet)        RX packets 7417  bytes 13726936 (13.0 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 6118  bytes 473182 (462.0 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0第二个容器运行，以联合网络的方式-----格式：Docker run -net=container:${container_id}[root@docker ~]# docker ps       #查看第一个容器的ID值CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES2f504d6966dc        centos:centos7      "/bin/bash"         6 minutes ago       Up 6 minutes                            thirsty_bhabha[root@docker ~]# docker run --rm -ti --net=container:2f504d6966dc centos:centos7[root@2f504d6966dc /]# ifconfigeth0: flags=4163  mtu 1500        inet 172.7.5.2  netmask 255.255.255.0  broadcast 172.7.5.255        ether 02:42:ac:07:05:02  txqueuelen 0  (Ethernet)        RX packets 15431  bytes 27381590 (26.1 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 13359  bytes 1061065 (1.0 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        loop  txqueuelen 1  (Local Loopback)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
