Native Packages
! Heart of OS applications stack
! Dependency handling
! Automatic or selective updates
! Widely used by Ops
! Well suited for Cloud based Operations

4. Jenkins User Conference Paris, 17 April 2012 #jenkinsconf
Linux Packaging
! RPM (Redhat Package Manager)
– RHEL/CentOS/ Fedora
– SLES/OpenSuse
– Mandriva
! DEB
– Debian
– Ubuntu

5. Jenkins User Conference Paris, 17 April 2012 #jenkinsconf
Package Definition
! A file(.rpm, .deb)
! An archive (Datas & Programs)
! Executed code at install, update or
remove time.
! Architecture related.
– Intel, ARM, PowerPC
– 32 or 64bits
! Or architecture neutral
– Java application
– Ruby library

Package Benefits
! Describing requirement
! Provide programs, datas and settings
! Registering in system service(ie: logrotate)
! Enforcing dedicated run account
! Total control over runtime cycle-life
– Installation
– Update
– Uninstallation
A package is much more than an archive

Maven common facts
! DSL build based
! Dependency Management
– At build time
– At deploy time
! Packages repositories
– In local mode
– Remotely via HTTP
! Nexus and Artifactory could act as RPM
repositories

8. Jenkins User Conference Paris, 17 April 2012 #jenkinsconf
From application to RPM
! 2 approachs
– OS Vendor way:
• Rebuilt from sources tarballs
• Require tarballs in build path
– Enterprise way:
• Rebuilt from Binaries (stored in Artifacts Repository)
• Avoid duplicate processing
• Trusting your delivery process

RPM building – SPEC FILE
! Sources
! Architecture
! Build Requirements
! Deploy Requirements
! Build
! Assembly
! Contents locations and rights

10. Jenkins User Conference Paris, 17 April 2012 #jenkinsconf
Jenkins as a Packages Factory
! Jenkins Master
– Get contents from SCM (Subversion, Git)
– Prepare build environment
– Trigger build on slaves
! Jenkins Slaves
– One slave by target (OS/Arch) platform
– Confident in OS compatibility
– Deployment on RPM repositories

Axway Packages Factory
! Builder
– 5 target OS
• CentOS 5 / 6 in 32 and 64 bits
• OpenSuse 12.1 in 32 and 64 bits
• Suse SLES 11 in 64 bits
! Distributor
– Apache HTTPd server
– Packages Repositories hosting and servicing
• 4 repos for CentOS 5/6 in 32/64 bits
• 1 repo for OpenSuse 12.1 32/64 and SLES 11.

Jenkins Factory in-depth
! Builder
– take control on slaves via SSH
– Trigger build jobs after SCM change
– Trigger jobs on 5/6 VMs via Matrix Plugin
! Slaves
– Build package on OS / Arch
– Send build packages to distributor via SCP
! Distributor
– Reindex repositories via cron if something change

Packages Tricks
! CentOS/RHEL use one repo by arch
– One repository for x86 32bits with native/noarch
– One repository for x86 64bits with native/noarch
è One slave by architecture for native
è Use one slave builder by arch even for noarch packages
! OpenSuse/SLES use a common repository
– One dir for x86 32bits
– One dir for x86 64bits
– One dir for noarch
è One slave by architecture for native
è You could use 32 or 64 bits builder for noarch packages
