Docker at Microsoft Build 2017

Build is Microsoft’s premier developer event, run annually. This year Docker, Inc. and containers were everywhere, starting with a dedicated container pre-day, then with constant traffic to the Docker booth, and many shared container success stories.Build is usually a three-day event, but this year saw the very first pre-day – run jointly by Docker and Microsoft. “Container Fest” was a whole-day event focused on containers and Docker, running on Windows and Linux, on-premises and in Azure.

The First DockerCon with Windows Containers

DockerCon 2017 is only a few weeks away, and the schedule is available now on the DockerCon Agenda Builder.

Convert ASP.NET Web Servers to Docker with Image2Docker

A major update to Image2Docker was released last week, which adds ASP.NET support to the tool. Now you can take a virtualized web server in Hyper-V and extract a Docker image for each website in the VM – including ASP.NET WebForms, MVC and WebApi apps.  Image2Docker is a PowerShell module which extracts applications from a Windows Virtual Machine image into a Dockerfile. You can use it as a first pass to take workloads from existing servers and move them to Docker containers on Windows. The tool was first released in September 2016, and we’ve had some great work on it from PowerShell gurus like Docker Captain Trevor Sullivan and Microsoft MVP Ryan Yates. The latest version has enhanced functionality for inspecting IIS – you can now extract ASP.NET websites straight into Dockerfiles. In Brief If you have a Virtual Machine disk image (VHD, VHDX Continue reading…

Learn Docker with More Hands-On Labs

Docker Labs is a rich resource for technical folks from any background to learn Docker. Since the last update on the Docker Blog, three new labs have been published covering Ruby, SQL Server and running a Registry on Windows. The self-paced, hands-on labs are a popular way for people to learn how to use Docker for specific scenarios, and it’s a resource which is growing with the help of the community. New Labs Ruby FAQ. You can Dockerize Ruby and Ruby on Rails apps, but there are considerations around versioning, dependency management and the server runtimes. The Ruby FAQ walks through some of the challenges in moving Ruby apps to Docker and proposes solutions. This lab is just beginning, we would love to have your contributions. SQL Server Lab. Microsoft maintain a SQL Server Express image on Docker Hub that runs in a Windows Continue reading…
