# Continuous Deployment
# ---------------------
#
# This file is a post-receive hook to be installed in the
# ./hooks/ dir of a bare git repository.
#
# When pushing to that repo from outside (a dev machine,
# or a jenkins/gitlab ci_cd rule), it updates a working dir previously
# set by cd to ${TARGET} and get the latest code .
# How to set it up:
# -----------------
#
# On the server to deploy:
#
# 1- create a bare repository and set hook
# git clone url-to-central-repo deploy-repo.git
# cp post-receive.git-hook deploy-repo.git/hooks/post-receive
#
# 2- set a working dir and configure
# cd /var/www/
# git clone deploy-repo.git your-app-dir
# do_any_config_tasks
#
#
# On the desktop computer:
#
# 1- add the server as a remote source
# git remote add deploy url-to-deploy-repo.git
#
# 2- try it out
# git push deploy HEAD:BRANCH_NAME
#
# $TARGET: is the working dir you want to update at last
# $BRANCH: is the branch you want to update from
#
TARGET="/var/www/pdc-web/"
BRANCH="DEV"
GIT_DIR="/path/to/pdc-web.git/"
while read oldrev newrev ref
do
# only checking out the branch you would like to deploy
if [ "$ref" = "refs/heads/$BRANCH" ];
then
echo "Ref $ref received. Deploying ${BRANCH} branch to production..."
[ -d $TARGET ] || exit
git --work-tree=$TARGET --git-dir=$GIT_DIR checkout -f $BRANCH
cd $TARGET || exit
touch *wsgi # now, trigger wsgidaemons restarting
/bin/sh scripts/post-deploy.sh
else
echo "Ref $ref received. Doing nothing: only the ${BRANCH} branch may be deployed on this server."

done
# Alternately, it is possible to just update a git repo
# git stash # remove any modification, sorry guy.
# git checkout ${BRANCH} # set branch if not done yet, sorry guy
# git pull origin ${BRANCH} # get latest modifications, assumes remote origin previously set
# exec git update-server-info
# vim: ft=sh
