简介 一.bridge模式
1.简介
如图所示docker完整安装后会自动创建一个docker0网桥不指定网络模式的情况下docker程序默认将程序与docker0虚拟网桥连接通过docker0来与宿主机通信。每运行一个docker都会在主机中产生对应的虚拟veth网卡设备运行的docker都是和docker0虚拟网桥位于同一网段docker0的地址作为docker的网关地址
bridge模式下主机和dockerdocker与docker之间可以互相通信 2.演示

1.简介
host模式下容器没有地理的网络命名空间不会新增网卡设备和宿主机共用网络命名空间使用宿主机的IP和端口
2.演示
运行一个容器并且可以在容器内只看到和宿主机共用的IP
[rootlocalhost ~]# docker run -it -d -p 80:80 --name web1 --network host nginx:1.14-alpine

docker exec requires at least 2 arguments.

[rootlocalhost ~]# curl 192.168.2.190
hello三.container模式
1.简介
指定这个模式下新运行的容器和已经存在的容器共享命名空间、IP、端口等不和宿主机共享。可以理解为这两个容器之间在网络方面产生绑定关系可以通过lo环回网卡设备通信。
2.演示
[rootlocalhost ~]# docker run --name nginx1 -it --network container:web1 nginx:1.14-alpine
#web1为被共享的docker
四.none模式
简介
none模式下docker容器拥有自己的网络命名空间此时不为任何docker容器进行网络配置需要自定义网卡和IP等等。此模式下docker不参与网络通信仅能访问本地环回接口适用于无需网络的环境中的离线任务。
