Problem with module 'openssl.digest'

[Xav59]

Hi,

I'm trying to use kong-oidc-auth plugin in a fresh install of Kong in Docker.
I'm using the latest official Kong Docker image with Kong version 2.2.1.
The installation of the plugin is okay using luarocks install kong-oidc-auth.
But when I startup Kong, I get the following error stack:

2020/12/10 14:56:08 [error] 1#0: init_by_lua error: /usr/local/share/lua/5.1/kong/tools/utils.lua:652: error loading module 'kong.plugins.kong-oidc-auth.handler':

Do you have any advice?

I just tested with version 2.0.5 of Kong, also using Docker, and I don't have the problem, the server starts without any error.

[franviera92]

which is the solution on kong 2.2.1?

[saroha87]

Basically openssl-dev is missing. So need to install openssl-dev in your linux of choice, then run "luarocks install luaoss".

Docker image to include this plugin

FROM kong:2.6.0-alpine
USER root
RUN apk update && apk add git unzip build-base luarocks openssl-dev
#RUN luarocks install kong-oidc
RUN luarocks install lua-resty-jwt 0.2.2-0
RUN luarocks install lua-resty-openidc 1.7.2-1
RUN luarocks install luaossl
RUN luarocks install kong-oidc-auth
USER kong

Hmm I guess Kong removed one of the older dependencies they used to bundle in their installs. Any community members want to take a crack at adding it to this plugins dependencies and we can rebuild and cut another version :) . If not I will give a go at it.

[jeremyjpj0916]

Actually added:

dependencies = {
  "luaossl == 20220711-0",
}

To the rockspec and latest version build, should be the only dep. needed seems. Let me know if works for yall?
