11-docker 三种网络简单介绍

1.查看docker网络

[root@docker03 ~]# docker network ls
NETWORK ID          NAME                DRIVER              SCOPE
a66de95d526f        bridge              bridge              local
51e1ca20a9e5        host                host                local
d218e92e7a5a        none                null                local

2.指定镜像容器使用的网络

[root@docker03 ~]# docker run -it --rm --net=none alpine sh
