This is a simple PHP script for Github's post-receive webhook

1. Setup your repository on Github, if you haven't already

2. On the deployment server, get an SSH key for the web user.

   • Assuming this is apache, to find the web user, run: ps aux | egrep "httpd|apache" -- may be apache, _www, www-data. Let's assume it's www-data:

       sudo mkdir /var/www/.ssh/
       sudo chown www-data:www-data /var/www/.ssh/
       sudo -Hu www-data ssh-keygen -t rsa
       [default dir of /var/www/.ssh/ is fine, no password]
       sudo cat /var/www/.ssh/id_rsa.pub
     

3. Add the SSH key as a deploy key in Github, https://github.com/your-account/your-repo/settings/keys

4. Clone the deploy script to a web-accessible location, git clone git://github.com/mboynes/github-deploy.git

5. Add a deploy-config.php file and in it define constants to override the defaults:

    # A regex matching the ref of the "push". <code>git pull</code> will only run if this matches. Default is the master branch.
    define( 'REF_REGEX', '#^refs/heads/master$#' );
   
    # Log location; make sure it exists
    define( 'LOG', '../logs/deploy.log' );
   
    # Where is your repo directory? This script will chdir to it. If %s is present, it gets replaced with the repository name
    define( 'REPO_DIR', dirname( __FILE__ ) . "/wp-content/themes/%s/" );
   
    # If set to true, $_POST gets logged
    define( 'DUMP_POSTDATA', false );
   
    # In your webhook URL to github, you can append ?auth={{ this field }} as a very simple gut-check authentication
    define( 'AUTH_KEY', 'enter-anything-you-want-here' );
   
    # Where is your git binary, and what command would you like to run?
    define( 'GIT_COMMAND', '/usr/local/bin/git pull' );
   
    # Do we want to do IP verification?
    define( 'VERIFY_IP', true );
   

6. Create the log directory and file, and make sure the user running apache (www-data) has write access to it.

7. In your Github repository, add a WebHook URL. Go to Settings/Admin -> Service Hooks -> WebHook URL (https://github.com/your-account/your-repo/settings/hooks). Add in the URL for your deploy.php file, append ?auth=something if you set the AUTH_KEY. For example, http://deploy.example.com/deploy.php?auth=foobar123

8. Clone your repository, if you haven't already. Do so as the web server's user, sudo -Hu www-data git clone [email protected]:your-account/your-repo.git

9. If you go back to the WebHook URL page in Github, you can test your webhook. Check your log, and make sure it's all set!
