Preview: Linux Containers on Windows

Microsoft is getting ready for the next big update for Windows Server (check out today’s complimentary Microsoft blog post) and some of the new features are very exciting for Docker users. One of the most important enhancements is that Docker can now run Linux containers on Windows, using Hyper-V technology. Running Docker Linux containers on Windows requires a minimal Linux kernel and userland to host the container processes. This is exactly what the LinuxKit toolkit was designed for: creating secure, lean and portable Linux subsystems that can provide Linux container functionality as a component of a container platform. We’ve been busy prototyping LinuxKit support for Docker Linux containers on Windows and have a working preview for you to try. This is still a work in progress, and requires either the recently announced  “Windows Server Insider” or Windows 10 Insider builds. Continue reading…

Docker on Windows Webinar Q&A

Recently I presented Docker on Windows: from 101 to Modernizing .NET Apps, a live webinar on using Docker with Windows, and running .NET Framework apps in containers. The session was recorded and you can watch it on the Docker YouTube channel: I start with the basics of Windows Docker containers, showing how to you can run containers from public images, and write Dockerfiles to package your own apps to run in containers. Then I move onto Dockerizing a traditional ASP.NET WebForms app, showing you how to take existing apps and run them in Docker with no code changes, and then use the Docker platform to modernize the app – breaking features out of the monolithic codebase, running them in separate containers and using Docker to connect them. I maxed out the session time (just like Mike with his Docker for the Continue reading…

Docker for Windows Server and Image2Docker

In December we had a live webinar focused on Windows Server Docker containers. We covered a lot of ground and we had some great feedback – thanks to all the folks who joined us. This is a brief recap of the session, which also gives answers to the questions we didn’t get round to.

Containerize Windows workloads with Image2Docker

Yesterday, we held a packed webinar on using the Image2Docker tool that prototypes shifting a legacy Windows virtual machine to a Windows Container Dockerfile. Image2Docker is an open source, community generated powershell module that searches for common components of a Windows Server VM and generates a Dockerfile to match. Originally created by Docker Captain Trevor Sullivan, it is now an open source tool hosted in our GitHub repository. Currently there is discovery of components such IIS, Apache, SQL Server and more. As an input it supports VHD, VHDX, and WIM files. When paired with Microsoft’s Virtual Machine Converter, you can start with pretty much any VM format. Image2Docker is community supported and designed to show you how easy it is to create Windows Containers from your existing servers. We strongly encourage you to fork it, play with it and contribute pull Continue reading…

New Dockercast episode with Mano Marks from Docker

In case you missed it, we launched Dockercast, the official Docker Podcast last month including all the DockerCon 2016 sessions available as podcast episodes. In this podcast, we meet Mano Marks, Director of Developer Relations at Docker.  Mano catches us up on a lot of the new cool things that are going on with Docker.  We get into the new Docker 1.12 engine/swarm built-in orchestration. We also talk about some cool stuff that is happening with Docker and Windows as well as Raspberry Pi and Docker. You can find the latest #Dockercast episodes on the Itunes Store or via the SoundCloud RSS feed.     New #dockercast episode w/ host @botchagalupe & our very own @manomarks as a guest! Click To Tweet
