Git post commit deploy

post-commit.sh

#!/bin/sh
# set -x
# set -v
#
#
# This script deploys your code to the production/ LIVE site.
#
# To make use of this git hook, it can be copied to `.git/post-commit`
# in the folder root.  It's then triggered after each git commit.
# Git offers hooks on many different git activities and, this custom
# hook checks if we are on the "master" or "develop" branch and, if so
# and the user responds "Yes" to the prompt, will copy the current code
# to a git "current-deploy-release" branch.
#
# Note that our MediaTemple instance listens for commits to that branch.
# After MediaTemple receives a update notification, it's able to download
# latest code, run configuration import updates, clear caches and run cron.
#
# No files need to be rearranged to run the hook successfully.
# It's important your current directory has vendor files and a working
# drupal instance.
