测试

docker ps查看运行中的容器，我这边tomcat-mynet-02、tomcat-mynet-01是用的mynet网络，tomcat902、tomcat901是默认的docker0。

[root@VM-0-3-centos pdx_haokai]# docker ps

执行ping测试

[root@VM-0-3-centos pdx_haokai]# docker exec -it tomcat-mynet-02 ping tomcat902
ping: tomcat902: Name or service not known

添加connect连接后，再执行ping

[root@VM-0-3-centos pdx_haokai]# docker network connect mynet tomcat901
[root@VM-0-3-centos pdx_haokai]# docker exec -it tomcat-mynet-02 ping tomcat901

结论

结论：如果需要跨网络操作别的容器，就使用docker network connect来打通网络。比如docker 搭建redis集群。
