PHP git hook deploy

Used for automated deploy web site code from Bitbucket to Dreamhost test site.

When push branch 'master' to bitbucket, the post hook will invoke this url:

http://git:pass@yourdomain.com/git-hook.php

then this script will pull the origin/master down.

Usage

1. Copy the both files to your Dreamhost site web root.
2. Add post hook URL into your bitbucket repo admin panel.
3. Initialize your git repo on Dreamhost, including add remote as a ssh protocol.
4. Add the ssh public key to Bitbucket deploy keys.
5. Checkout the branch you want to deploy So that the pulled code will be present on your site.

Thanks

@thorakmedichi No. It's only hardcoded in this script to match the basic HTTP authentication you set in post hook service panel.

NOT FOR COMMON SERVER THAN DREAMHOST (PHP based)

I have worked it out to a new project hookagent to handle most deployment on common server rather than Dreamhost (PHP only). And I moved it to node.js and shell based which much simpler.

Hope you will find it useful!
