How to change config file of nginx runing via docker

I have installed sharelatex from this image https://github.com/sharelatex/sharelatex-docker-image via docker on Windows 7 with this command line

 $ docker run -d --name sharemongo mongo:latest
    $ docker run -d --name shareredis redis:latest
    $ docker run -d -P -p 80:80 -v /opt/sharelatex --env SHARELATEX_MONGO_URL=mongodb://mongo/sharelatex --end SHARELATEX_REDIS_HOST=redis --link sharemongo:mongo --link shareredis:redis --name sharelatex sharelatex/sharelatex
    and it seems to work

It could run. But i have problem with upload a larger file (>2mb) . One person told me that just add this line into config file nginx

client_max_body_size 8m;

But i don't know how to change the config file in nginx that already running via docker.

Thank you


Solution 1:

As far as I know, you can either fork out/edit the nginx.conf in the repo you have cloned or you can point the Dockerfile to the path of your custom nginx.conf.
