Some folks aren't clear on the limitations. Linux containers will never run on bare metal using Windows Server OS. Virtualization will be required and you will incur that performance penalty. This is Microsoft appeasing it's current users. They aren't making any effort to get folks to switch from Linux as far as I can tell.

You're wrong. They don't care if you run Windows or Linux. They want you to run it on Azure.

You have no idea. Unless Windows start shipping with a Linux kernel, Linux containers will always be slower on Windows.

What is this multiplatform container application they talk about? Is it a Hyper-V container with small Linux runtime? Or a docker-compose file with some containers running on Windows and some on Linux (e.g. ASP.NET on Windows and Redis on Linux)?

My experiences running Docker on Ubuntu on MS virtualization have been negative to lukewarm. First annoyance was dealing with dynamic memory allocation for the linux host, which works fine (I'm told) for Windows VMs, but had to be turned off. Second was some DNS issues, but it could just be that we have a shitty admin. Nevertheless, Linux (and by extension Docker) and Windows are strange bedfellows IMO. I don't get t…

Thanks for the comments, fixxer. For the comment on memory allocation, I would love to know more details about where you saw problems as we are always trying to make Linux run better on Azure (and Hyper-V). For DNS, I would be surprised if this was the virtualization stack although it can be tricky to set-up DNS in the cloud.

For our partnership with Docker, it has already been very valuable to MS. With Azure, we want to offer customers and partners the ability and flexibility to deploy applications from any ecosystem and find many of our customers want to deploy both Windows and Linux as part of their application. For us, Docker offers an amazing API that spans the underlying container technology, for both Windows Server and Linux, to enable deployment, management and orchestration with the exact same tools and solutions. For example, the same Docker Client works against a Windows Server host and a Linux host.

We are excited to continue to partner with the Docker community, as our customers really do want this consistent experience, on Azure, on-premises and even in other clouds across Windows and Linux.

Great question. Because the containers pull from the underlying host operating system, you will be able to deploy a Windows Server Container on a Windows Server host but you cannot deploy a Linux container on a Windows Server host (and vice versa).

However, you can run either a Windows VM or a Linux VM on Hyper-V (or in Azure).

Also, you can now run .NET applications on Windows or Linux. But that is a bit orthogonal to your question. :)

Hopefully that helps.

Is this different from what was announced yesterday, and if it is, can someone please give us an accurate non-PR-speak title?

Let me give it a shot, very succinctly (although I am constantly being told I am too verbose). Here is what Mark demo'd today at DockerCon:

1) We showed an application deployment, using Docker, of a Windows Server Container (running Node) and a Linux container (running .NET). The exact same Docker client can be used for deployment and managing both.

2) We showed DockerHub integration in Visual Studio Code with intelligent code complete (it auto-fills the DockerHub image you want). Visual Studio Code is a free version of Visual Studio that runs on MAC/Ubuntu: https://code.visualstudio.com/

3) We showed Visual Studio Online continuous integration that packaged and deployed a Docker container using Swarm/Compose on Azure.

4) We showed Azure Marketplace deployment of DockerHub images, that will deploy and configure multiple Docker containers onto Azure Linux VMs (we showed one that deploys both a wordpress and MySQL container on a single Linux host using compose).

5) We showed the Docker Trusted Registry image available to deploy from the Azure Marketplace.

Hopefully that helps (and has removed marketing speak? :)).

I will second Corey's request - we've been working to make sure that dynamic memory and other features of Hyper-V are first class experiences on Linux, if you can share details on what issues and what versions you had them on that would be really helpful.

Sure. I'll ask for logs tomorrow. Emails?
