Liberty in Docker on a Raspberry Pi

It seems like everyone is looking at what they should be <em>containerising</em> (yes, that's a word!) in <a href="https://www.docker.com/">Docker</a> to help improve their development, test, and production pipelines. With the recent <a href="/wasdev/docs/deploying-applications-docker-1-12-liberty/">release of Docker 1.12</a>, it's now easy to deploy Docker on a <a href="https://www.raspberrypi.org/">Raspberry Pi</a>. As Liberty was <a href="https://twitter.com/WASdevnet/status/763744610627776512">the first application server to be shown running on a Raspberry Pi</a> we're always looking at how we can take advantage of the awesome little computers. So I set off on a mission to see how easy it is to get a Raspberry Pi-compatible Docker image of Liberty, and then to see how many instances of that image I can run on a single Raspberry Pi.

Getting Java apps talking to Arduino

Arduino is an open source, low-powered, low-cost microcontroller. It's often used in Internet of Things projects to take input from sensors in the environment and to respond appropriately. As a developer, you write a 'sketch' which then runs continuously on the Arduino to tell it how to behave. With this sample Arduino feature for Liberty profile, you can write Java applications that interact with one or many Arduinos. Continue reading Getting Java apps talking to Arduino

Build the Liberty Car (Part 1): The hardware

At IBM Impact 2013, we introduced <a href="/wasdev/blog/2013/04/25/liberty_controlled_car/">the Liberty Car</a>. We replaced the radio receiver in a radio controlled car with a <a href="https://www.raspberrypi.org/">Raspberry Pi</a>. Then, with the help of <a href="/wasdev/websphere-liberty/">WebSphere Liberty</a>, we added hardware and software to make it possible to drive the car from any device with WiFi and a web browser. Part 1 describes how to build the hardware. Continue reading Build the Liberty Car (Part 1): The hardware

WebSphere Application Server running on the Raspberry Pi

Following the recent <a href="https://www.ibm.com/developerworks/mydeveloperworks/blogs/wasdev/entry/websphere_application_server_v8_5_announced_april_24th12?lang=en">announcement of WebSphere Application Server V8.5</a>, we decided to show how lightweight the Liberty Profile really is, by running it on lightweight hardware, the Raspberry Pi. Check out this video to see just how lightweight our new developer profile is. Continue reading WebSphere Application Server running on the Raspberry Pi
