whats-my-ip

A tiny "Whats my IP address" - service written in Lua, using the lua-http library.

Installation

Currently it is recommand to run this service behind nginx. In the future it should be possible to run it standalone too, but for this a few features are missing. This installation assume you're using Debian or Ubuntu, but should work on other systems too, when you replace the package manager commands.

Dependencies

Install dependencies

apt install lua5.3 nginx
  • Create a new user
adduser wmia
  • Login as the user:
su -l wmia
  • Clone the repository
git clone https://git.kokolor.es/imo/whats-my-ip-address.git
  • Change into the new folder
cd whats-my-ip-address/
  • Initialize luarocks for this project
luarocks init

The benefit is, that luarocks will now install new modules in this folder, which keeps the rest of the system clean. But if you want to install the modules for the whole user or the whole system you can do this as well.

  • Now install the modules via luarocks
luarocks install http
luarocks install mimetypes
luarocks install luafilesystem
  • Rename the sample config file and edit it with your favorite editor
cp config.cfg.lua{.sample,}
  • Log back in as root and copy the systemd service file if you use systemd
cp /home/wmia/whats-my-ip-address/install/wmia.service /etc/systemd/system/
  • Before activating the service, check if all paths are correct in the service file. If you didn't use luarocks init make sure you change the path to the Lua executable in ExecStart.
systemctl enable wmia.service
systemctl start wmia.service

If all paths are correctly, the service should start and be reachable locally

  • I don't describe how to configure nginx here, but you can find an example configuration in /install, which you can use

TODO

  • Create Dockerfile
  • Documentation (e.g. usage, installation)
  • maybe reverse dns
  • maybe geoip = http://geoip.nekudo.com
