Winter 2010 Posters/Koji Builder
Title
Koji Builder by: David Cabral (dpcabra1@learn.senecac.on.ca)
Introduction
The goal was to create machines/builders that work with the koji-hub to build packages on the ARM (armv5tel) architecture. Fedora Project doesn't have the resources to maintain the ARM architecture for all its packages and with the increase of actual ARM systems being used, the need of builders have too increased. Kojid is the build daemon that runs on the build machines. It's primary responsibility is polling for incoming build requests and handling them accordingly. Kojid is written in Python and communicates with koji-hub via XML-RPC.
Description
Setting up the builders according to the koji-hub configuration. The builder relys heavily on the koji-hub to be configured before kojid could functional. Kojid and koji-hub need to communicate with each other, so we use SSL Certifications to authenticate the requests. Each builder needs it's own certificate and needs to be put in the PostgreSQL database. Kojid uses Mock to create a chroot of a minimal installation to test the packages and make sure they install correctly and if the SRPM work it creates all the RPMs. We used one actual ARM machine and nine virtual machines to familiarize the steps involved in getting builders to work with a Koji Hub. The final goal is to make an Koji farm dedicated to building ARM packages for Fedora since the architecture is getting more and more popular everyday. Creating this farm will help with the Fedora Project Community development.
