The requested URL returned error: 500 Internal Server Error

Hi,

I can't get ssl work. The issue seems to be with reachability of the internal server at 127.0.0.1:8999. Below is the error logs:

2019/04/17 16:22:15 [error] 17#17: *8 [lua] hook.lua:15: server(): auto-ssl: failed to parse POST args: request body in temp file not supported, client: 127.0.0.1, server: , request: "POST /deploy-challenge HTTP/1.1", host: "127.0.0.1:8999"

And here's my Docker file:

FROM openresty/openresty:bionic

ARG USER=www-data
ARG GROUP=www-data

RUN mkdir -p /etc/letsencrypt &&\
openssl req -new -newkey rsa:2048 -days 3650 -nodes -x509 \
-subj '/CN=sni-support-required-for-valid-ssl' \
-keyout /etc/ssl/resty-auto-ssl-fallback.key \
-out /etc/ssl/resty-auto-ssl-fallback.crt

RUN luarocks install lua-resty-auto-ssl &&\
mkdir /etc/resty-auto-ssl/ &&\
chown -R $USER:$GROUP /etc/resty-auto-ssl/

RUN rm -f /usr/local/openresty/nginx/conf/*

RUN mkdir -p /var/log/nginx &&\
touch /var/log/nginx/access.log &&\
touch /var/log/nginx/error.log

RUN ln -sf /dev/stdout /var/log/nginx/access.log &&\
ln -sf /dev/stderr /var/log/nginx/error.log

EXPOSE 80
EXPOSE 443

COPY ./configs /usr/local/openresty/nginx/conf

CMD ["/usr/local/openresty/bin/openresty", "-g", "daemon off;"]

What am I missing?

Start with hook.lua:15, then read lets_encrypt.lua:41 and ssl_certificate.lua:97 alongside the Dockerfile and copied nginx configuration. Reproduce the HTTP-01 certificate request and inspect why the deploy_challenge POST uses a temporary request-body file. Done means the challenge request succeeds without a 500 response and certificate issuance completes.
