Yea that still doesn't answer my long standing statement docker fixes an obsolete problem. We already have better ways to handle initializing a raw VM image to a full application server (cloud init is messy but more than workable). While I'm not 100% wild about dracut it is extremely useful for light weight Paravirtualization in the sense that it can make the Linux Kernel in a standard distro require less ram than it has in more than a decade. Finally containers are no more than a kernel enforced chroot and still have all of the same problems to a systems admin that made most of them shy away from chroot in the 80s the difference is now many "web developers" think they know better than sysadmins on how everything works. By the way I put web developers in quotes to clarify that those people are not really qualified web developers but mostly kids just out of college given a title in there first job at a new startup. By the way these are the same kids who post and vote on segfault, stackexchange, etc..

Docker and Microsoft unite Windows and Linux in the cloud

*DockerCon 2015* Microsoft has doubled down on its support for Docker,
further integrating the software container tech with Azure and Visual
Studio Online and demoing the first-ever containerized application
spanning both Windows and Linux systems.
The software giant first showed off its support for Docker on its Azure
cloud at the DockerCon conference in June 2014. Then in October it said
it would introduce Docker-compatible containers for Windows
in the next version of Windows Server.
At this year's DockerCon, which took place in San Francisco earlier this
week, attendees could stop by Microsoft's booth to see Windows
Containers in action – although there's still no word on a release date
for a version of Windows Server that supports them.
Then, during Tuesday morning's DockerCon keynote, Microsoft Azure CTO
Mark Russinovich went one step further by giving a demo of a
containerized application where some of the code ran on Linux and some
on Windows Server.
Cleverly, he pushed a container with the ASP.Net portion of the code to
the Linux server, while the Windows host ran a container with the
Node.js portion. Ordinarily you might expect it to work the other way
around.
To drive the point home, there were plenty of free T-shirts available at
the Microsoft booth on the subject of uniting Windows and Linux via
Docker. There were even buttons with the catchphrase that Microsoft CEO
Satya Nadella coined
in
November, "Microsoft ♥ Linux."
Microsoft Loves Linux
Who'da thunk it?
Docker, Docker everywhere
Behind the scenes, Docker's own orchestration tools
– including Docker Compose and Docker Swarm – handled the grunt work for
both operating systems. But Russinovich didn't need to muck about with
the command line, thanks to the newly implemented integration of
Docker's tools with Visual Studio.
Russinovich first demonstrated how the IntelliSense feature of Redmond's
free, cross-platform Visual Studio Code
editor
worked with Docker container configuration files. For example, it
detected when he was typing the name of an image file and IntelliSense's
code completion feature automatically pulled in a list of possible
matches direct from Docker Hub.
Support for publishing projects to Docker hosts is coming to the
full-fat Visual Studio IDE, Russinovich said. But for his demo, he
instead used Visual Studio Code to upload his project to Visual Studio
Online
,
which also now includes Docker integration.
The upload automatically triggered a series of continuous integration
(CI) steps, Russinovich said, such as building Docker images, running
containerized unit tests, pushing the images to Docker Hub, creating a
Docker Swarm cluster on a collection of Azure VMs, and finally pushing
the composed, multi-container application to the cluster.
And if you do plan to deploy your containerized apps on Azure,
Russinovich added, Microsoft has made that easy for you, too. Beginning
on Tuesday, you can now deploy Dockerized applications via the Azure
Marketplace, including ones composed of multiple containers.
The Azure Resource Manager and the Management Portal have also been
updated so that admins can specify configuration options for Dockerized
apps, not just for the virtual machines onto which they will be deployed
but also for the containers that will be launched on the virtual machines.
It's still early days yet for Microsoft and containers, but Redmond is
clearly all-in on the concept. The proof? In addition to everything he
demoed onstage at DockerCon, Russinovich had another bombshell to drop.
Since the beginning of May, he said, the Number One contributor to the
open source Docker code base has been Microsoft. ®
