The new app is fully integrated with the OS. There is no need to run docker-machine start xxx and eval $(docker-machine env xxx).It comes with its own lightweight VM based on xhyve. You don't need Virtualbox or VMware Fusion.The Docker app is a native app, which you install by copying its icon to the /Application folder.It's a private beta: you need to apply and wait to be given an operational token, but once you are in, you notice the differences between the beta and the "old" Docker-Toolbox: That can't be done on a Mac, because the host computer is a virtual machine, and even though Docker can access a folder in your Mac, the server installation fails for lack of permissions.īoth the above restrictions are lifted if you use the beta release of Docker for Mac and Windows. telling the container to run the data directory in a virtual path that refers to some safe place in the host computer. The proper way of achieving data persistence with containers is through volumes, i.e. The second limitation I found affects only MySQL, and it is related to using volumes. This happens with any application that listens to a port. I showed one of those issues in a recent article ( MySQL and Docker on a Mac: networking oddity.) When you want to export a port from a service running in the container, the exported port is not available in your mac, but in the virtual machine that runs Docker services. If you develop on a different operating system (OSX or Windows) there are several restrictions. If you develop on Linux, the above statement holds. Using Docker for development is a great way of ensuring that what you develop will be the same that you deploy in production.
