Local git mirror of github used by private Jenkins

gistfile1.txt

So I've installed a dead simple backup, in /home/USER/git_backup/:

    git clone --mirror [email protected]:USER/PROJECT.git
    update.sh (launched every 5 minutes by cron):

#/bin/sh

cd /home/USER/git_backup/PROJECT.git
LINES=`git remote update 2>&1 | wc -l`

if [ $LINES -eq 1 ]; then
   # only one line "Fetching origin"?
   echo "Project didn't changed"
else
   echo "Project changed, notify jenkins builds"
   curl http://JENKINS:8080/git/[email protected]:USER/PROJECT.git
fi

This keeps a perfect copy (mirror) of the PROJECT github repository, and if there's a change when doing the "git remote update", jenkins is notified, and it'll then poll github to check if it should run the builds related to the url provided.

minor grammar nit: https://gist.github.com/jsoref/861d5584b4b1af9c7248884d5d51ddf2/6b3413aaa138406468190740a66c27ea2c1432bb
