Simple Git deploy script for PHP apps

Usage

SSH into your server then copy deploy.sh, deploy.json, and deploy_post_hook.sh.

git clone https://gist.github.com/8816795.git

Then set your configs in json and run:

./deploy.sh deploy.json

How it works

Here is what deploy.sh does:

1. check for current deploy number on server (based on dir names)
2. create new deploy dir for current version + 1
3. copy master branch from GitHub via svn into new deploy dir (will prompt for credentials)
4. call your post deploy hook, which can link public_html -> new deploy public dir
5. ?
6. profit
