node-plus-nginx-dynamic-ip

A way to quickly update nginx configuration with dynamic ip, by replacing nginx variable value by correct ip

How to use it

Minimal requirement

Tested with success on Ubuntu 16, all Unix like system should work with this package. Windows system may be support in a future release. Working nginx with site conf loaded.

###Install & Run

    $> npm install -g node-plus-nginx-dynamic-ip
    $> node-plus-nginx-dynamic-ip
    Listening for request on port 15000

##Configure

On the first run, it will say No site were registered in /path/to/conf.unix.json Simply open with your favorite editor the specified path, and add site like in conf.example.unix.json

{
  "port": 15000,
  "site-available": "./test/res/sites-available",
  "site-registered": [
    {
      "file": "test.myserver.com.conf",
      "variable_name": "ip_of_my_host",
      "protocol": "https"
    }
  ]
}

Use case

My case was the following :

    raspberry-pi (XXX.XXX.XXX.XXX) <-> Home modem (Dynamic ip : YYY.YYY.YYY.YYY) <-> My external server (myserver.com)

###Client side

Or simply, how to update my nginx conf to proxy_pass on the correct IP ? With this basic crontab :

@hourly wget -O /dev/null bind.myserver.com/mysite.conf

My raspberry pi tell myserver.com that it ip should be used by nginx in mysite.conf.

###Server side

• Load the configuration (witch site may be updated)
• Listen for http request from remote client (like my raspi)
• On each request, open correspondent file (test.myserver.com.conf) and update the variable ip_of_my_host
• Reload nginx
