首先明确两点: 1只有自定义网络,才能手工指定每个容器的ip.默认的bridge是不行的! 2 手工设定了网段比如172.19.0.0   不影响docker在host装的网卡docker0 的172.17.0.1 容器内的172.19.0.XX  还是可以通过172.17.0.1访问到主机. docker-compose.yml  参考官网 https://docs.docker.com/compose/compose-file/#network-configuration-reference…

docker网络介绍 大量的互联网应用服务需要多个服务组件,这往往需要多个容器之间通过网络通信进行相互配合. docker 网络从覆盖范围可分为单个 host 上的容器网络和跨多个 host 的网络.docker 目前提供了映射容器端口到宿主主机和容器互联机制来为容器提供网 络服务,在启动容器的时候,如果不指定参数,在容器外部是没有办法通过网络来访问容器内部的网络应用和服务的. docker安装时,会自动在host上创建三个网络: [root@localhost ~]# docker netwo…
