Question

我想从docker容器连接到我的本地主机服务。我正在使用docker for mac。我查看了此链接How to access host port from docker container，但是当我在docker容器中运行ip addr show docker0时。我收到ip addr show docker0错误回复。以下是我的docker容器上的所有网络设备。

哪一个是我的本地主持人地址？

Answer 1

您可以使用特殊的Mac-only DNS名称docker.for.mac.localhost，这将解析为主机IP。

Answer 2

您可以docker run --network host ...允许docker容器访问主机端口。或使用network_mode中的选项docker-compose.yaml。但是，如果您使用不受信任的Docker映像，则此模式可能会成为安全问题。
