Fuel is an open source deployment and management tool for OpenStack. Developed as an OpenStack community effort, it provides an intuitive, GUI-driven experience for deployment and management of OpenStack, related community projects and plug-ins.

Fuel brings consumer-grade simplicity to streamline and accelerate the otherwise time-consuming, often complex, and error-prone process of deploying, testing and maintaining various configuration flavors of OpenStack at scale. Unlike other platform-specific deployment or management utilities, Fuel is an upstream OpenStack project that focuses on automating the deployment and testing of OpenStack and a range of third-party options, so it’s not compromised by hard bundling or vendor lock-in.

Shotgun takes a yaml files with command lines as argument so that it can collect log files and such to help diagnose problems in Fuel.
