After years I am now migrating my development environment from vagrant to docker. I was always very pleased about the way vagrant worked but running a complete VM is a bit of overhead and beside that very resource consuming. It’s also less flexible, its more work to maintain for example. After reading about Linux Containers, how they work I got interested in Docker. Now I am working on my own docker development environment. While I am building such environment I experience sometimes difficulties, some easy to overcome and some harder. Today I had an issue with mounting volumes from my windows machine using docker compose. The problem was that the mount just didn’t work. So what is the problem?
