Day8 不同yml檔，也可以讓容器彼此都能溝通

只要網段一致，即可直接呼叫IP或容器名稱。因此，這邊示範如何在不同的容器中，讓他們有相同的網段。

solve: docker network can container access the localhost by host mode

 1.  

Lastly, under Linux you can run your container in the host network namespace by setting --net=host; in this case localhost on your host is the same as localhost inside the container, so containerized service will act like non-containerized services and will be accessible without any additional configuration.

3. ipforward

作業系統擁有 IP轉發（英語：IP forwarding）功能，意味著該系統能接收從接口傳送進來的 網絡數據包（英語：network packets），如果識別到該數據包不用於該系統自身，那麼系統將會將該網絡數據包傳送到另外一個網絡去，用恰當地方式轉發該數據包。^[1]

一個典型的場景是需要去搭建一個路由器以連接兩個不同網絡。

• Alpine 显然不适合作为Python 应用的基础映像。尽管它提供了惊人存储的空间上效率，但它对于Python包支持的不足的缺陷是难以弥补的。也许Alpine更适合于一些对于映像尺寸敏感的场合，还可以考虑将它用于你的Go 应用。
