如何将第3方lua库(通过luarocks安装)加载到haproxy中 [英] how to load 3rd party lua libs (installed via luarocks) into haproxy

问题描述

我正在编写将使用Lua API在HAproxy内部运行的lua脚本.

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

我的脚本使用的是socket软件包，我想将其安装在计算机上.

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

当前我正在docker内部运行，我的dockerfile如下所示:

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/

我的脚本下一行:

local http = require('socket.http')

在运行lua解释器时可以正常运行，但在运行haproxy时则不能运行:

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:

我应该如何正确地将其加载到haproxy?

How should I load this correctly to haproxy?

推荐答案

您可以在需要luasocket模块之前打印package.path和package.cpath值.

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

此值是lua存储加载库的路径的地方.

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