⁠Using as a base image

When using LuaRocks, be aware that many modules require a compiler. This requires us to temporarily add a few extra packages to our image.

For example, if we wanted to add the "httpclient" and "lua-cjson" modules to our image then we would add the following to our Dockerfile:

RUN apk add --update gcc lua5.2-dev musl-dev git \
    && export C_INCLUDE_PATH=/usr/include/lua5.2/ \
    && luarocks install httpclient \
    && luarocks install lua-cjson \
    && apk del gcc lua5.2-dev musl-dev git \
    && rm -rf /var/cache/apk/*
