The best way to learn Docker for Free: Play-With-Docker (PWD)

Last year at the Distributed System Summit in Berlin, Docker captains Marcos Nils and Jonathan Leibiusky started hacking on an in-browser solution to help people learn Docker. A few days later, Play-with-docker (PWD) was born.  PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode. Under the hood Docker-in-Docker (DinD) is used to give the effect of multiple VMs/PCs. In addition to the playground, PWD also includes a training site composed of a large set of Docker labs and quizzes from beginner to advanced level available at training.play-with-docker.com. In case you missed it, Marcos and Jonathan presented PWD during the last DockerCon Moby Cool Hack session. Watch the video Continue reading…

Developing a Spring Boot app on Docker: The AtSea Demo App

This is the first of a series of blog posts that demonstrates using Docker to develop a typical web application and deploying it in production. For DockerCon 2017, we wanted to build a new demo application that would demonstrate the flexibility of using Docker in development as well as showcase the features of Docker in a production environment. The result was the AtSea Shop, a storefront application that can be deployed on different operating systems and can be customized to both your enterprise development and operational environment. A Hybrid Architecture The team decided on a few ground rules. First, we wanted to use modern components commonly used in enterprise applications. We decided to build a Java application using the Spring Boot framework. The web client is a javascript application written using React as a framework.  Second, the application should be able to Continue reading…

DockerCon Hands-on Labs now online

One of more popular activities at DockerCon is our Hands-on Labs, where you can learn to use the Docker tools you see announced on stage, or talked about in the breakout sessions. This year we had eight labs for people to work through, ranging from 20 minutes to an hour in length. We’ve now moved these apps into the Docker Labs Repo so that everyone can use them. The Docker Labs Repo is where we put a bunch of learning content for people who want to learn Docker, from beginner to advanced security and networking labs. Here are the new labs: Continuous Integration With Docker Cloud In this lab, you will learn how to configure a continuous integration (CI) pipeline for a web application using Docker Cloud’s automated build features. Docker Swarm Orchestration Beginner and Advanced In this lab, you will play around Continue reading…

Docker Birthday #4: Thank you Docker Community!

Pақмет сізге, tak, धन्यवाद, cảm ơn bạn, شكرا, mulțumesc, gracias, merci, danke, obrigado, ευχαριστώ, köszönöm, thank you Docker community! From Des Moines to Santiago de Cuba, Budapest to Tel Aviv and Sydney to Cairo, it was so awesome to see the energy from the community coming together to celebrate and learn about Docker! We originally planned for 50 Docker Birthday #4 celebrations worldwide with 2,500 attendees. But over 9,000 people registered to attend one of the 152 celebrations across 5 continents! A huge thank you to all the Docker meetup organizers who worked hard to make these celebrations happen and offered Docker beginners the  opportunity to participate in hands on Docker labs. Join in on the fun! In case you missed it last week, check out the pics from all of the #DockerBday celebrations including the awesome birthday cakes! Check out the Facebook photo album too!

New Year’s Resolution: Learn Docker

Remember last year when I said the market for Docker jobs was blowing up? Well, it’s more than doubled in the last year. And Swarm is also rising quickly, growing 12829%, almost all of that in the last year. We expect that with our partnership with Microsoft and Windows Docker containers, that this will grow even faster in the next year as .NET developers start to containerize their applications and Windows IT Professionals start porting their infrastructure to Docker. Take a look at this trendline from indeed.com. So what are you doing to increase your Docker skills? Want a few suggestions? Whether you’re a developer or more an ops person, a great place to start is the Docker Labs repository, which has currently 28 labs for you to choose from. They range from beginner tutorials, to orchestration workshops, security and networking tutorials, and guides for using different programming 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…

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…

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…
