post-receive

## 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.
