如何让码头集装箱访问主机网络端口

Question

我想从码头集装箱连接到我的本地主机服务。我使用docker for mac。我检查了这个链接How to access host port from docker container，但是当我在Docker容器中运行ip addr show docker0。我得到了ip addr show docker0错误响应。以下是我的码头集装箱上的所有网络设备。

# ip addr show

     valid_lft forever preferred_lft forever 

哪一个是我的本地主机地址？

Answer 1

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