git-deploy

A PHP script to automatically pull from a repository to a web server (using a webhook on GitHub, GitLab, or Bitbucket).

You can configure which branch this script pulls from. This script is useful for both development and production servers.

On your server

SSH

Generate an SSH key and add it to your account so that git pull can be run without a password.

• GitLab documentation
• Bitbucket documentation

Configuration

Copy the git-deploy folder and its contents in to your public folder (typically public_html). Note that you can change the name of the folder if desired.

Rename git-deploy/config.sample.php to git-deploy/config.php, and update each variable to a value that suits your needs. An example of a live configuration is below.

define("TOKEN", "secret-token");
define("REMOTE_REPOSITORY", "git@github.com:username/custom-project.git");
define("DIR", "/var/www/vhosts/repositories/custom-project");
define("BRANCH", "refs/heads/master");
define("LOGFILE", "deploy.log");
define("GIT", "/usr/bin/git");
define("AFTER_PULL", "/usr/bin/node ./node_modules/gulp/bin/gulp.js default");

Permissions

When deploy.php is called by the web-hook, the webserver user (www, www-data, apache, etc...) will attempt to run git pull .... Since you probably cloned into the repository as yourself, and your user therefore owns it, the webserver user needs to be given write access. It is suggested this be accomplished by changing the repository group to the webserver user's and giving the group write permissions:

1. Open a terminal to the directory containing the repository on the server.
2. run sudo chown -R yourusername:webserverusername custom-project-repo-dir/ to change the group of the repo.
3. run sudo chmod -R g+s custom-project-repo-dir/ to make the group assignment inherited for new files/dirs.
4. run sudo chmod -R 775 custom-project-repo-dir/ to set read & write for both owner and group.
