Create a LUA enabled NGINX docker image

 

In this post we will review the steps to create a LUA enabled docker image.

NGINX LUA, is a JIT based scripting enable a highly customizable behavior.

The standard docker image is simply:

Dockerfile:

FROM openresty/openresty:1.19.3.1-8-centos7

On the nginx.conf, as part of the main context, we will need to enable LUA JIT:

pcre_jit on;

and as part of the http context of the nginx.conf, we will need to add the folder where our LUA scripts reside:

http {
    lua_package_path    '/usr/local/lib/lua/?.lua;/my-lua/?.lua;;';

Now, the NGINX is ready for LUA scripting.
