#!/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 |
And this can be simplified
to_remove=`git status | grep "deleted" | awk '{print $3}'`
if [ -n "$to_remove" ]; then
git rm --ignore-unmatch $to_remove
fi
to:
git status | awk '/deleted/ { print $3 }' | xargs -r git rm --ignore-unmatch
Final edition:
#!/bin/sh -e
cd "$JENKINS_HOME"
# Add general configurations, secrets, job configurations, nodes, user content, users and plugins info:
ls -1d *.xml secrets/ jobs/*/*.xml nodes/*/*.xml userContent/* users/*/config.xml \
plugins/*/META-INF/MANIFEST.MF 2>/dev/null | xargs -r -d '\n' git add --
# Track deleted files:
LANG=C git status | awk '$1 == "deleted:" { print $2; }' | xargs -r git rm --ignore-unmatch
LANG=C git status | grep -q '^nothing to commit' || {
git commit -m "Automated Jenkins commit at $(date '+%Y-%m-%d %H:%M')"
git push -q -u origin master
}

I'm noticing that when you restore jenkins, it's important to make sure the files are all owned by the jenkins user with the jenkins group or you might see the below error in the GUI:

transistorgit's comment was mangled by the Markdown renderer, but I think this was the intention:
The initial script works fine for me, but leaves out some more complex (deeper nested) jobs.
So I added
shopt -s globstar
at the beginning and changed
git add -- *.xml jobs/*/*.xml userContent/*
to
git add -- *.xml jobs/**/config.xml userContent/*
This script has one issue though, folders and build history are not saved.
