A tiny program help you deploy your code via git web hook

cd /path/to/your/repository
git reset --hard HEAD
git pull
deploy.sh    # Only if there is a deploy.sh file

First, build this tiny program via go build

Then, config your nginx like this:

    location /Admin/Deploy/YOUR-DEPLOY-KEY-HERE/ {
        proxy_pass  http://127.0.0.1:4321/path/to/your/repository;
    }

I suggest you to add that deploy key in path and use https request to prevent abuse.

You may notice the path in your request is exactly the path of repository. So please keep this little program behind firewall, use nginx for proxy instead.
