Run your application at full speed while syncing your code for development, finally empowering you to utilize docker for development under OSX/Windows/Linux*

Developing with docker under OSX/ Windows is a huge pain, since sharing your code into containers will slow down the code-execution about 60 times (depends on the solution). Testing and working with a lot of the alternatives made us pick the best of those for each platform, and combine this in one single tool: docker-sync

安装 docker-sync

$ gem install docker-sync
