DevOps Days India 2013: Build Radiator on Raspberry Pi
0 likes553 views
The document describes how to build a simple build radiator using a Raspberry Pi to display continuous integration build statuses. It discusses installing an operating system on the Pi, configuring the build servers and statuses in a YAML file, using Ruby code to retrieve the build statuses and display them with automatic refreshing. The builds are deployed to the Pi by cloning the code repository, installing dependencies, and starting the Ruby server. The final result is a low-cost build radiator that provides fast feedback and is environmentally friendly.
