From lines from error "nginx: [alert] failed to load the 'resty.core' module (https://github.com/openresty/lua-resty-core); ensure you are using an OpenResty release from https://openresty.org/en/download.html (reason: module 'resty.core' not found:"
It is suggesting to use complete openresty package from https://openresty.org/en/download.html
Can we just use resty.core module insted of whole package? If yes which version should i pick?

[oowl]

First, Openresty is a bundle of Nginx distribution, So I do not recommend building Nginx with lua-nginx-module to use the lua module, it can not guarantee all the functions of lua-nginx-module doc works fine due to Openresty bundle many patch and module to do some feature. You can see lua-nginx-module test CI bundles many repo codes to test all functions. https://github.com/openresty/lua-nginx-module/blob/master/.travis.yml#L81

Second, back to your issues, it's very clearly pointed out that the resty.core module can not be found. You need to clone lua-resty-core module to your lualib path location of the Nginx build prefix that will let luajit interrupt find the resty.core module.

[lynch1981]

to solve this issue, you can install lua-resty-lurcache to /usr/local/share/lua/5.1

Just modify Makefile like this, and run make install

LUA_VERSION := 5.1
PREFIX ?=          /usr/local
LUA_INCLUDE_DIR ?= $(PREFIX)/include
LUA_LIB_DIR ?=     $(PREFIX)/share/lua/$(LUA_VERSION)
INSTALL ?= install

.PHONY: all test install lint

download

Hello @lynch1981
I added lua-resty-lurcache
Still facing few config errors like
[root@a143b7d21bd5 nginx]# "/usr/sbin/nginx" "-e" "/dev/stderr" "-g" "daemon off;"
nginx: [emerg] open() "/var/lib/nginx/tmp/nginx.pid" failed (2: No such file or directory)

[lynch1981]

You start nginx with root privileges, so it's not a permissions issue
It looks like the path "/var/lib/nginx/tmp" does not exist
