Koji Hub Installation and ConfigurationBuild System for Fedora ARM

At the beginning of the Winter 2010 semester the Software Build and Release 600 class The goal was to set out to create a Koji build system for the ARM architecture. Koji is the software that builds and tests packages for the Fedora Project. At The software package used by Fedora is called an RPM and provides a means for easy installation, removal and updating. The process of building software on a platform ensures that all the center necessary files are available for that software package to function in the given hardware environment. Currently we are aware of one other Koji operations Build System for the ARM architecture which is the Koji Hublocated in Germany. The plan was to initially set up all components of the Koji build system on the one server, with the Koji builder Daemons running on Virtual ARM Machinesand the physical hardware as it arrives. Planned hardware includes various applications of the ARM processor. After installation and configuration of the PostgreSQL, the Koji Hub would be configured, followed by the other components of Koji including the Koji Web, Kojira and finally the set up of the actual builders themselves. 

Mock - mock is a tool that creates a protected and minimal Linux file system that is used to test build software packages. = Results Problems Encountered =At * Initially the close of Virtual Machines had no network connectivity, network settings and devices had to be added manually before becoming functional. * Problems using the semester we currently have PostgreSQL database - installation for use with Koji required a functional Koji Build systemstandard installation. The After the first attempt PostgreSQL was reinstalled successfully and Koji Hub is was successfully dispatching packages able to the Koji builder Daemons and Kojira is creating new repositories for use interact with the ARM architecturedatabase. On the path to success some issues encountered included

= Problems Encountered =* Authentication using SSL certificates - Problems using the PostgreSQL databaseThe SSL certificates posed some authentication issues due to conflicting configurations when generated. The certificates were recreated and authentication was successful.

* Various configuration issues - After what appeared to be a successful installation and throughout the process the different configuration, Koji builders files that required editing were listed as not being fully functionalmis-configured, this appeared or needed to be an issue edited multiple times to work correctly with the Koji Hub but was later determined to be a lack of disk space on the Koji buildersconfiguration.

* The creation of repositories by Kojira was failing after 2919/12788 software packages (RPMS), additional memory was added to the Virtual ARM Machines an the repository creation continued. * Lack of documentation - Authentication using SSL certificatesbecause this is the second Koji Build System for the ARM architecture, there are limited resources. Within weeks of starting work and blogging on Koji, our blogs became the top results when searching the internet.- Various configuration issues* Understanding the relationship of package creation and Koji's method of organizing software packages in the database. This is still a learning process as Koji has just become fully functional.

= Summary Results =Currently we have a functional Koji Build system. The Koji Hub is successfully dispatching packages to the Koji builder Daemons and Kojira is creating new repositories for use with the ARM architecture. Eight VM's and the Open-RD Client are online and set of conclusions =are listed as Ready and Enabled using the Koji command line tool and the web interface through Koji Web. Koji Web can be used to monitor all Koji operations and provide real time log information that can be used to troubleshoot problems as they arise.
