桥接器端口容器端口到主机端口

Question

我使用以下命令运行docker容器:

docker run -d --name frontend_service -net host --publish=3001:3000 frontend_service

据我所知,它将本地端口3001映射到容器端口3000.我已经ssh到容器并检查curl localhost:3000.作品.但在外面,在主机上,我无法卷曲localhost:3001.

我查了一下nmap.该港口是开放的:

nmap -v -sT localhost

如何将容器端口与主机端口连接？

Answer 1

指定时--net=host,您完全关闭了Docker的网络设置步骤.容器不会获得自己的网络命名空间,也不会获得自己的接口,端口发布系统将无法路由到.

如果您希望自己-p 3001:3000的工作,请不要使用--net=host.
