Git push to prod

post-receive

#!/bin/sh

# Use git to push to deploy (aka git push to prod)
# Use 'git push remote master' to push to deploy
# This script only deploys on pushes to master.  
#
# HOWTO:
# On your server to deploy, create a bare git directory 
# (somewhere like /var/git/<gitProject>)
# Your depoly directory (like /var/www) should be somewhere other than your git repo.  
#
#     git --bare init
#
# Put this script into <gitProject>/hooks/post-receive on the deploy server
# Make sure this script has execute permissions (chmod +x post-receive)
# Then add this remote repo as a remote in git.  
#
#     git remote add deployServer ssh://example.com/var/git/<gitProject>
#
# Then use ssh to push to production.
#
#     git push deployServer master
# 
# You can create a group (like "git"), make it owner of this file 
# Then add every user that needs to push to the that group.
# See http://security.stackexchange.com/a/72951/17878 for more background.

            echo 'Master branch.  Pushing to prod'
            push

            echo 'Not on master.  Not pushing to prod'

What is the purpose of this script ? Should I put the script on my private git server or on the hosting server (where I pull the code with the git client) ? What is not clear to me, it's your definition of production server.

Hi @borgogelli. I've updated the gist with a better description. Let me know if this answers your question.

Does this still work? I know now that the file is named ‘push-update’ instead of ‘push-receive’

Yes, it should be working.
