Docker for Mac and Windows Beta

link says its Hyper-V on Windows, but then says Windows 10 only... Anyone know if Windows Server is also supported?

> Faster and more reliable: no more VirtualBox!

I'm a Docker n00b, still don't know what it can do exactly. Can Docker replace Virtualbox? I guess only for Linux apps, and suppose it won't provide a GUI, won't run Windows to use Photoshop?!

"the simplest way to use Docker on your laptop"

I think they forgot about Linux :)

Let me explain Docker for Mac in a little more detail [I work on this project at Docker].

Previously in order to run Linux containers on a Mac, you needed to install VirtualBox and have an embedded Linux virtual machine that would run the Docker containers from the Mac CLI. There would be a network endpoint on your Mac that pointed at the Linux VM, and the two worlds are quite separate.

Docker for Mac is a native MacOS X application that embeds a hypervisor (based on xhyve), a Linux distribution and filesystem and network sharing that is much more Mac native. You just drag-and-drop the Mac application to /Applications, run it, and the Docker CLI just works. The filesystem sharing maps OSX volumes seamlessly into the Linux container and remaps MacOS X UIDs into Linux ones (no more permissions problems), and the networking publishes ports to either `docker.local` or `localhost` depending on the configuration.

A lot of this only became possible in recent versions of OSX thanks to the Hypervisor.framework that has been bundled, and the hard work of mist64 who released xhyve (in turn based on bhyve in FreeBSD) that uses it. Most of the processes do not need root access and run as the user. We've also used some unikernel libaries from MirageOS to provide the filesystem and networking "semantic translation" layers between OSX and Linux. Inside the application is also the latest greatest Docker engine, and autoupdates to make it easy to keep uptodate.

Although the app only runs Linux containers at present, the Docker engine is gaining support for non-Linux containers, so expect to see updates in this space. This first beta release aims to make the use of Linux containers as happy as possible on Windows and MacOS X, so please reports any bugs or feedback to us so we can sort that out first though :)

Biggest problem with Boot2docker was volume mounting and file permissions, hope this happens soon. > Volume mounting for your code and data: volume data access works correctly, including file change notifications (on Mac inotify now works seamlessly inside containers for volume mounted directories). This enables edit/test cycles for “in container” development
