Yes to databases in containers – Microsoft SQL Server available on Docker Store

Microsoft SQL Server 2017 is now available for the first time on multiple platforms: Windows, Linux and Docker. Your databases can be in containers with no lengthy setup and no prerequisites, and using Docker Enterprise Edition (EE) to modernize your database delivery. The speed and efficiency benefits of Docker and containerizing apps that IT Pros and developers have been enjoying for years are now available to DBAs.   Try the Docker SQL Server lab now and see how database containers start in seconds, and how you can package your own schemas as Docker images.   If you’ve ever sat through a SQL Server install, you know why this is a big deal: SQL Server takes a while to set up, and running multiple independent SQL Server instances on the same host is not simple. This complicates maintaining dev, test and CI/CD systems where Continue reading…

Video Series: Modernizing .NET Apps for IT Pros

  This is a new 5-part video series in Docker’s Modernize Traditional Apps (MTA) program, aimed at Microsoft IT Pros. The video series shows you how to move a .NET 3.5 app from Windows Server to a Windows Docker container and deploy it to a scalable, highly-available environment in the cloud – without any changes to the app. Part 1 introduces the series, explaining what is meant by “traditional” apps and the problems they present. Traditional apps are built to run on a server, rather than on a modern application platform. They have common traits, like being complex to manage and difficult to deploy. A portfolio of traditional applications tends to under-utilize its infrastructure, and over-utilize the humans who manage it. Docker Enterprise Edition (EE) fixes that, giving you a consistent way to package, release and manage all your apps, without having to re-write 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 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. This will be the first DockerCon since Windows Server 2016 was released, bringing native support for Docker containers to Windows. There will be plenty of content for Windows developers and admins – here are some of the standouts. Windows and .NET Sessions On the main stages, there will be hours of content dedicated to Windows and .NET. Docker for .NET Developers Michele Bustamante, CIO of Solliance, looks at what Docker can do for .NET applications. Michele will start with a full .NET Framework application and show how to run it in a Windows container. Then Michele will move on to .NET Core and show how the new cross-platform framework can build apps which run in Windows or Linux containers, making for true Continue reading…

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…
