About me

!  CI Architect @ Axway ! Was Senior Ops Director ! Was Developer, TL and Architect ! JPackage Project Founder ! OpenJDK 7 & 8 packages for OSX !  ASF Member (Tomcat & XMLRPC)

Native Packages

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

Jenkins User Conference Paris, 17 April 2012 #jenkinsconf

Linux Packaging

!  RPM (Redhat Package Manager) –  RHEL/CentOS/ Fedora –  SLES/OpenSuse –  Mandriva

!  DEB –  Debian –  Ubuntu

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

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

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

Jenkins User Conference Paris, 17 April 2012 #jenkinsconf

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

Jenkins User Conference Paris, 17 April 2012 #jenkinsconf

Jenkins Factory in-depth

Parallel build on slaves (Matrix) Build binaries

uploaded via SCP

Repositories reindexed by cron if update detected

New packages immediatly available

remotely via HTTP

Initial method – 1 Job / OS-Arch

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
