creating a docker image with nginx compile options for Optional HTTP modules

Question

I am trying to build an nginx image for installing nginx with the Module ngx_http_auth_request_module.

this is my current docker file:

#ubuntu OS
FROM ubuntu:14.04

#update apt-get non interactive and install nginx
RUN \
  sudo apt-get -q -y update; \
  sudo apt-get -q -y install nginx

#copy all mapping configurations for all environments
COPY ./resources/routing-configs/* /routing-configs/

#expose port for nginx
EXPOSE 80

#run task to copy only relevant mapping configuration to nginx and reload nginx service
COPY ./resources/start.sh /opt/mysite/router/start.sh
RUN sudo chmod 766 /opt/mysite/router/start.sh
CMD sudo -E sh /opt/mysite/router/start.sh

typically i would have compiled the nginx files locally like this:

sudo ./configure --with-http_auth_request_module

and then install nginx

sudo make install

but how can i do this with docker file?

please help

I'm somewhat of a noob with Docker, but I had to solve this same problem. I used this Dockerfile as a starting point.

FROM centos:centos7

WORKDIR /tmp
