On Windows, Hyper-V doesn't really play nicely with laptops. If you've got it enabled and bridged to your wifi adapter, Windows 10 may think that your connection is Ethernet and turn off all bandwidth saving features. I only found out after Windows Update had exhausted my monthly LTE quota.

Speaking about Windows, it is also disabled on Windows 10 Home and only available on Pro edition. Hope they'll maintain VirtualBox support as a first-class citizen (well, given that it was the most mature option during the beta period, suppose they will).

No, GP got it right.

The quoted part is that instead of VirtualBox one can use Hyper-V. In either case, it's handled by docker-machine which runs a GNU/Linux VM with Docker (host) tools installed, and containers are ran on that VM.

I would be surprised if there aren't plans to support WSL (to run Linux-targetting binaries on Windows "natively", thus have "native" Docker containers) but don't think that's available yet.

Sadly, the state of things, be it the Docker ecosystem or others, "ready for production" means something much different than it did years ago. For me, the definition of ready for production, Debian is a good example of the opposite end of Docker.

I think by 'production', they mean 'ready for general use on developer laptops'. No one in their right mind is deploying actual production software on Docker, on OS X/Windows. I've been using it on my laptop daily for a month or two now, and it's been great. Certainly much better than the old Virtualbox setup.

The fact that I can have Bash up and running in any distro I feel like within minutes blows my friggin mind. Docker is the stuff of the future. We were considering moving our development environment to Docker for some Fun, but we're still holding off until it is more stable and speedy.

On the other hand I find my old setup with VMware much more reliable and performant. And I can continue to use the great tools to manage the VM instead of being limited to what docker provides. Some advanced network configuration is simply impossible in docker's VM.

I doubt the problems mentioned happen on Linux or CoreOS, which is likely what a production environment will run on.

Docker for Windows is to isolate Windows software.

It's not a tool to test Linux containers on Windows.

The deployment target for Docker containers for Windows will be a Windows OS.

Can I run my usual VirtualBox VMs I have running for everything else (non-docker related) alongside Docker for Windows yet? When I tried one of the betas it enabled Hyper-V which prevented me from using any of my other VMs.

You can have just one hypervisor working at any given time. So, no, you can't use your VirtualBox VMs while a Docker container is running in this way (because it'd be using Hyper-V/xhyve).

"This version of Docker requires Windows 10 Pro, Enterprise or Education edition with a minimum build number of 10586. Please use Docker Toolbox." :(

Meaning it doesn't run on LTSB as well (10240). Too bad, it's the only sane version of Windows 10 yet.

An interesting fact I think is worth mentioning is that Docker for Mac uses a forked and currently closed version of xhyve, and not the same xhyve that we can find on Github. The last commit to open source xhyve was May 27.

With that said Docker has plans to open source it, I wonder if that will happen soon as they declare Docker for Mac ready for production. That would imply that the xhyve port also should be ready be contributed back or spin out into a new project (the quote below said they were not sure if they wanted to contribute back or make a new project).

Personally I think the "right thing to do" would be to contribute back to xhyve, at the same time I have a feeling it's more valuable for Docker Inc to "own" and control their own fork/project so I would guess they will go down that path instead (it would still be open source, just under a different project name).

EDIT: I stand corrected, see talex5 comment below, I had missed the hyperkit announcement.

Sadly, no, they're using the name "Docker for Windows" to refer to the Docker-on-Linux-in-a-VM-on-Windows version.

Real native Windows containers and a Docker shim to manage them are coming: [1] but not released yet.
