What kiwi is and what it’s not

KIWI is: A command line based toolkit Usable as part of a process chain Usable as base tool for a high level application KIWI is not: A product

kiwi history

riginated by Marcus Sch¨

afer

riginal purpose was creating “system on a stick”

James Willcox (snorp) joins active development for Thin Client (SLETC) Jigish Gohil (CyberOrg) joins active development: LTSP project I join active development for Autobuild extension I’ll get back to the last point later

Current project status

Used for the following products: SLEPOS – SuSE Linux Point of Sale SLETC – SuSE Linux Thin Client Hardware vendors for preload images Community projects: Developers who deliver Live DVDs (KDE, openSUSE, . . . ) users who want to make images containing their application . . . ? (You tell me)

Setting up the buildhost

Install kiwi, kiwi-tools and kiwi-desc-* packages create an image description file config.xml, or get and modify an existing image description

Theory and History A Real Life Example What else? Questions and Answers Closing The Configuration Directory

Contents of the Configuration Directory

config.xml contains every necessary image information(packages, repositories, settings, . . . config.sh customise the image after the packages are installed image.sh ditto root/ contains overlay files which are included in the image or needed in scripts

ther special YaST files and others

The main thing to do is tweaking the config.xml.

Requirements and Regressions

You developed a distributed application as Diploma Work (for example) You have to give a “public” demonstration You have virtually no control over the hardware for the demo

SLIDE 17

Theory and History A Real Life Example What else? Questions and Answers Closing Solution

One Possible Solution

Your program is available as RPM package: add a plain RPM folder to your repositories add the package name to the <packages> section Build your image

Jan-Christoph Bornschlegel <jcborn@suse.de> SUSE Linux Products GmbH - Build Service Team System Imaging with KIWI

SLIDE 18

One Possible Solution II

Your program is not available as RPM package: Get a BuildService account and package it ;) put all needed files into your image manually Build your image

Theory and History A Real Life Example What else? Questions and Answers Closing Autobuild System

Purpose

Autobuild is current internal package and media factory

penSUSE BuildService will be the next generation

package factory kiwi can not yet create installation sources not yet. . .

SLIDE 22

Theory and History A Real Life Example What else? Questions and Answers Closing Autobuild System

How it works

Autobuild is a distributed system Build clients build single RPMs based on a central scheduler and source base every employee’s machine can (and should) be a build host scheduler collects built rpm files to internal “full trees” for each codebase and architecture metadata is created

Theory and History A Real Life Example What else? Questions and Answers Closing Product Creation now and then

Current Product Creation

full trees for target architectures are sync’d to dedicated machines rpm files are selected and collected to one repository metadata for this particular repository is created finally all sorts of media are made:

ftp repositories CD, DVD, torrent, . . .

SLIDE 25

Theory and History A Real Life Example What else? Questions and Answers Closing Product Creation now and then

Product Creation with kiwi

Collecting the target repository must be integrated into kiwi. Expansion of the config.xml syntax add module for repository creation allow priority value for repositories allow exceptions implement script hooks Autobuild knowledge is necessary to create package lists and scripts
