updates.sh

updates.sh is a shell script written by Cogent, that does customization of the Jenkins interface for Fuego.

This program is called during the Docker container build, to customize the Jenkins installation for Fuego. It copies lots of static files into jenkins jar files, then installs them. Overall, it's extremely fragile and version dependent.

steps [edit section]

Here are the steps it does:
  • scan jenkins var file for JENKINS_CORE_NAME
    • set to WEB-INF/lib/jenkins-core-1.509.2.jar
  • make all files under /var/lib/jenkins owned by user 'jenkins'
  • make all files under /var/lib/jenkins/war owned by user 'jenkins'
  • get jenkins-cli.jar from running local server.
    • restart server if there are problems
  • cd en_US
  • customize main page html:
    • cp *.xml to /var/lib/jenkins (and fix permissions)
      • hudson.plugins.page_markup.PageMarkupPageDecorator.xml
      • locale.xml
  • customize plugins
    • jar -uf ./* each plugin in en_US/plugins/* (and fix permissions)
      • jar -uf $p.jpi or $p.hpi ./*
  • copy en_US/css to /var/cache/jenkins/war
  • copy en_US/images to /var/cache/jenkins/war
  • customize core classes:
    • extract jenkins core: jar xf /usr/share/jenkins/jenkins.var WEB-INF/lib/jenkins-core-1.509.2.jar
    • update core jar with junk: for d in hudson, jenkins, lib:
      • jar uf WEB-INF/lib/jenkins-core-1.509.2.jar $d/*
    • cp core jar to /var/cache/jenkins/var
    • fix permissions
  • install plugins (CSS & locale)
    • restart jenkins
    • get jenkins-cli.jar (again?)
    • use jenkins-cli.jar to install-plugin

data files [edit section]

In the directory: en_US, there are a bunch of files used to customize the Jenkins interface. Here is the rough directory structure:
  • core
    • hudson
      • widgets
      • init
      • model
      • cli
      • matrix
      • views
      • lifecycle
    • jenkins
      • model
      • management
    • lib
  • css
  • images
  • plugins
    • compact-columns
    • dashboard-view
    • PrioritySorter
    • jobConfigHistory
