Voting with Docker: A little break from the election

You may have heard, there’s an election for president (and many other posts) going on in the US today. For those who already voted, who want a break from voting, or just want to create a new quiz for their friends, we have the Docker Example Voting App. And we’ve even created a poll to help you figure out the best quiz to make. Which #Docker voting app face off would you select? #TwitterPoll #ElectionDay — Docker (@docker) November 8, 2016 The voting app was created to showcase a number of features of Docker: Polyglot development environments: The app has Python, Node.js, and .NET code, as well as Redis and Postgres services. Easy deployment of a multi-service app with Docker Compose. Easy Docker Networking. All this using a simple $ docker-compose up. The Example Voting App has been really popular at 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…

Even more Docker Labs!

Since we launched Docker Labs back in May, we’ve had a lot of interest. So we keep adding more and improving the labs that we have. We now have 22 hands on labs for you to choose from, ranging from beginner tutorials to much more advanced ones. Here’s a peek at what we have: To accompany the launch of Windows containers in Microsoft Windows Server 2016, we launched a Windows Container beginner tutorial to walk you through setting up your environment, running basic containers and creating a basic Docker Compose multi-container application using Windows containers. We added 6 security tutorials to take advantage of some of Docker’s strong security features. A Docker community member liked our Java debugging tutorials so much, he translated our labs into Spanish. We added a new Node.js tutorial to show how to easily you can debug Node.js applications live in 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…

Docker Labs Repo Continues to Grow

Back in May, we launched the Docker Labs repo in an effort to provide the community with a central place to both learn from and contribute to Docker tutorials. We now have 16 separate labs and tutorials, with 16 different contributors, both from Docker and from the community. And it all started with a birthday party. Back in March, Docker celebrated it’s third birthday with more than 125 events around the world to teach new users how to use Docker. The tutorial was very popular, and we realized people would like this kind of content. So we migrated it to the labs repository as a beginner tutorial. Since then, we’ve added tutorials on using .NET and Windows containers, Docker for Java developers, our DockerCon labs and much more.     Today we wanted to call out a new series of tutorials on developer tools. Continue reading…

Docker Hub Hits 5 Billion Pulls

Last week, the total number of image pulls from the Docker Hub Repository Service reached 5 billion. That’s an increase of 150% since just February. It’s pretty amazing for a three year old project. Docker Hub has become a part of the daily life of developers because it

Swarm Mode on a Raspberry Pi Cluster

Last week I sat down with Dieter Reuter from Hypriot. Dieter is a Docker Captain who spends a lot of time working with ARM and Raspberry Pis in particular. Dieter told me how excited he is by Swarm Mode in particular because of how easy it would be to set-up a collection of Internet of Things devices to work together securely. So we took a look at how easy it is to set-up a Raspberry Pi cluster and run Docker 1.12 in Swarm Mode. Here’s how he ran Swarm Mode: So if you want to set-up a cluster of your own, he’s provided this helpful guide with a bit more details on how to set-up a Raspberry Pi Cluster in 29 minutes. Also a number of people have asked after the visualizer that he’s using in demo. This is a Continue reading…

Announcing the Docker for Mac and Windows Public Beta

Back in March, we launched a private beta for a new ambitious project called Docker for Mac and Docker for Windows. Our major goal was to bring a native Docker experience to Mac and Windows, making it easier for developers to work with Docker in their own environments. And thousands agreed. Over thirty thousand applied in the first 24 hours. And by last week, we let in over seventy thousand. And now all you need to get started developing is Docker and a text editor. No more installing dependencies and runtimes just to debug applications.
