Developing and testing Docker container can be problematic on Windows 10 if you have different type of container. Suppose that you have one Linux container and one Windows Container that need to communicate, the simple solution to communicate through host ip address (Docker bridge actually is not working in mixed mode); but if your IP is not stable (you move on different network)? Do you need to change the hostname/IP in every configuration file. But there is a more simple solution: Microsoft loopback adatper. If you install this virtual adapter and assign a fixed IP, containers can communicate using this IP, that not change if you change network. Simple solution for speed-up developing process.
