Hello Guys,
Its been a long time after which i am writing a blog on a automation recently i got a requirement about backup the Jenkins into a git and since after a quick search on internet i find it out there is no such plugin available i have to do it the hard way
Requirement : Backup all Jenkins important config files (xml) in git on daily basis
Now there are two ways to do it
- Write a script and schedule it in cron to execute it on midnight
- create a Jenkins job for this and let the backup script get executed using jenkins
I like the 2nd approach as it will give a transparency I did not need to login to a box just to check if my script is working or not also i can send an email if i wanted to if some thing goes wrong and its easy to keep an eye on if some thing goes wrong
So lets get started
create a jenkins job its a free style jenkins job
in the General config you will find the option
Restrict where this project can be run : in the label expression write master .
Source code management : None or you can have it if you want to check out your script from git every time you want to execute the job
Build Trigger : Build Periodically in the schedule write 0 0 * * * while means you need to execute it on daily basis
Build : in the build section select Execute shell
copy paste the below shell script
#!/bin/bash
# Setup
#
# - Create a new Jenkins Job
# - Mark "None" for Source Control Management
# - Select the "Build Periodically" build trigger
# - configure to run as frequently as you like
# - Add a new "Execute Shell" build step
# - Paste the contents of this file as the command
# - Save
#
# NOTE: before this job will work, you'll need to manually navigate to the $JENKINS_HOME directory
# and do the initial set up of the git repository.
# Make sure the appropriate remote is added and the default remote/branch set up.
#
# Jenkins Configuraitons Directory
cd $JENKINS_HOME
# Add general configurations, job configurations, and user content
git add -- *.xml jobs/*/*.xml userContent/*
# only add user configurations if they exist
if [ -d users ]; then
user_configs=`ls users/*/config.xml`
if [ -n "$user_configs" ]; then
git add $user_configs
fi
fi
# mark as deleted anything that's been, well, deleted
to_remove=`git status | grep "deleted" | awk '{print $3}'`
if [ -n "$to_remove" ]; then
git rm --ignore-unmatch $to_remove
fi
git commit -m "Automated Jenkins commit"
git push -q -u origin master
save the job
Login to jenkins server from shell Now Go to the Jenkins Home directory usually its a /var/lib/jenkins
also make you the public key(/var/lib/jenkins/.ssh/id_rsa.pub) for jenkins user is added to the github so that it will be able to push it
# git init
# git add remote <github repo url where you need to backup your jenkins>
once done we are all set to test it. Let me know how it works for you
