how to load 3rd party lua libs (installed via luarocks) into haproxy

I'm writing lua script that is going to run inside HAproxy using it's Lua API.

My script is using socket package which I want to install on my machine.

Currently I'm running inside docker and my dockerfile looks like this: 

FROM haproxy:1.7

RUN apt-get update -y &&  apt-get install curl luarocks -y
RUN luarocks install luasocket

EXPOSE 80 9000

COPY 500error.json.http /etc/haproxy/errorfiles/
COPY hello_world.lua /etc/haproxy/scripts/

my script have the next line:

local http = require('socket.http')

which works okay when running lua interpreter but not when running haproxy:

[ALERT] 298/104833 (8) : parsing [/usr/local/etc/haproxy/haproxy.cfg:5] : lua runtime error: /etc/haproxy/scripts/hello_world.lua:1: module 'socket.http' not found:

How should I load this correctly to haproxy?

You can print package.path and package.cpath values just before require luasocket module.

This values is where lua store paths to load a library.
