Node.js express app to receive github and bitbucket Git POST hook and automate code deployment.

Deploy Hook is is just simple Node.js git pull application triggered by git hosting hook notifications.

• Set git repository for your apps in both your development machine and deployment server
• Set SSH keys in both machines
• Clone deploy hook app
• Adjust config.js
• Run deploy hook app in your server
• Set Hook url on your git hosting (github or bitbucket)
• See notes below
• Commit and enjoy

When execute with Node.js exec, git run on different environment than you usual command line bash. Make sure you set correct gitPath and keyPath in config.js. I tested this on my machine on Windows 7 32 bit and Windows Server 2012 64 bit. You might need to modify config file and path accordingly.

My applications are running on IIS with iisnode. It turns out that even with setting keyPath directly git pull just won't work. One solution is to copy .ssh folder from HOME directory (Usually something like : C:\Users\Administrator\.ssh) into your Git installation path C:\Program Files (x86)\Git\.ssh.

With above approach you can use git pull origin master directly. Apparently when executed with Node.js exec(), git looks for SSH keys in C:\Program Files (x86)\Git\.ssh folder.

Note that this app has basic auth in it. So your POST hook url should be like https://user:password@serverhost:serverport/helper/v1/deploy/hook

If you see function deploy in deploy.js you will notice that I separate staging and production deployment using branch information from github Webhook body or bitbucket POST hook body.

I also include sample payload in function getHook in deploy.js. You can create your own custom deployment suitable for your needs and use POST body accordingly

This code is intended for private repository as it's using SSH key. If you have public repository you can skip SSH config settings.
