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…

WEBINAR Q&A: Modernize Traditional Applications with Docker Enterprise Edition

This week at DockerCon, we announced the Modernize Traditional Applications (MTA) Program to help enterprises make their existing legacy apps more secure, more efficient and portable to hybrid cloud infrastructure. This webinar covers the importance of “WHY NOW and HOW” to start modernizing traditional applications with Docker Enterprise Edition. Legacy applications often serve critical business needs and have to be maintained for a long time. The maintenance of these applications can become expensive and very time consuming. Some applications may have been written decades ago, grown to millions of lines of code  and the team that built and deployed the app may no longer be at your company. That can pose a challenge for app maintenance, security and support. Docker Enterprise Edition and the Image2Docker Tool presents a unique opportunity to modernize these apps into containers to make them portable, more secure and 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…

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…

Webinar Recap: Docker for Windows Server 2016

Last week, we held our first webinar on “Docker for Windows Server 2016” to a record number of attendees, showcasing the most exciting new Windows Server 2016 feature – containers powered by Commercially Supported Docker Engine. Docker CS Engine and containers are now available natively on Windows and supported by Microsoft with Docker’s Commercially Supported (CS) Engine included in Windows Server 2016.Now developers and IT pros can begin the same transformation for Windows-based apps and infrastructure to reap the benefits they’ve seen with Docker for Linux: enhanced security, agility, and improved portability and freedom to run applications on bare metal, virtual or cloud environments. Watch the on-demand webinar to learn more about the technical innovations that went into making Docker containers run natively on Windows and how to get started. Webinar: Docker for Windows Server 2016 Here are just a few Continue reading…

Image2Docker: A New Tool for Prototyping Windows VM Conversions

Docker is a great tool for building, shipping, and running your applications. Many companies are already moving their legacy applications to Docker containers and now with the introduction of the Microsoft Windows Server 2016, Docker Engine can now run containers  natively on Windows.To make it even easier, there’s a new prototyping tool for Windows VMs that shows you how to replicate a VM Image to a container. Docker Captain Trevor Sullivan recently released the Image2Docker tool, an open source project we’re hosting on GitHub. Still in it’s early stages, Image2Docker is a Powershell module that you can point at a virtual hard disk image, scan for common Windows components and suggest a Dockerfile. And to make it even easier, we’re hosting it in the Powershell Gallery to make it easy to install and use. In Powershell, just type: Install-Module -Name Image2Docker And Continue reading…
