Docker access container IP/Port directly
我有实验用的码头集装箱。因此,我不知道稍后在尝试新应用程序时将使用哪些端口。在不在docker run命令中公开的情况下,是否可以从主机访问具有IP/端口的docker容器应用程序?
Docker for Mac is unable to route traffic to containers, and from containers back to the host.

更新:OP没有在原来的问题中提供关于
原始答案:
是的,你能做到。
假设您有一个名为
要找到此IP,您可以使用以下方法来
1 | docker container inspect boring_pare |
此外,您还提到:
Isn't it possible to access docker container application with ip/port from the host without exposing it in the docker-run command?
这里的正确术语是出版。进一步阅读:
关于
EXPOSE 或dockerfile的文件
...The
EXPOSE instruction does not actually publish the port. It functions as a type of documentation between the person who builds the image and the person who runs the container, about which ports are intended to be published. To actually publish the port when running the container, use the-p flag ondocker run to publish and map one or more ports, or the-P flag to publish all exposed ports and map them to to high-order ports.Docker中"公开"和"发布"的区别
