With a few tiny tweaks to your Mac, you can connect with Docker containers running on Weave Net and Docker for Mac, without exposing ports on the Docker host – which is great for testing and debugging during application development. Debugging and testing containerized applications from a Mac can be fiddly, (because you’re running containers inside a Host, which itself is running inside the OS), especially if you have multiple containers using the same port or if a second port is assigned to a value not known before a process starts (JMX, I’m looking at you).
