I'm just getting started with the Lua framework called Lapis, but I encountered a problem when I tried to install it into a docker cointainer.

I’m using the official OpenResty image (jessie), and want to extendmy Dockerfile with a “luarocks install lapis” command.

When I try to build the image I get this error:

ERROR: Service 'nginx' failed to build: The command '/bin/sh -c luarocks install lapis' returned a non-zero code: 1

And then this one:

lapis 1.6.0-1 depends on lua-cjson (not installed)

Installing https://luarocks.org/lua-cjson-2.1.0-1.src.rock

lua_cjson.c:1298:13: error: static declaration of 'luaL_setfuncs' follows non-static declaration

            ^



In file included from lua_cjson.c:44:0:

                 ^

Error: Failed installing dependency: https://luarocks.org/lua-cjson-2.1.0-1.src.rock - Build error: Failed compiling object lua_cjson.o

gcc -O2 -fPIC -I/usr/local/openresty/luajit/include/luajit-2.1 -c lua_cjson.c -o lua_cjson.o

What causes the error?

Try this docker image with Lapis preinstalled. It's based on Alpine Linux and uses the latest versions of OpenResty and Lapis.
And here is the Dockerfile if you want to reproduce it:

ARG RESTY_IMAGE_BASE="openresty/openresty"

ARG RESTY_IMAGE_TAG="1.13.6.2-alpine"



FROM ${RESTY_IMAGE_BASE}:${RESTY_IMAGE_TAG}



LABEL maintainer="Dmitry Golovin <dima@golovin.in>"



ARG RESTY_LUAROCKS_VERSION="3.0.2"
