How is it easier and more competent to connect your nginx.conf inside the container?

Question

Nginx

Good afternoon,

there is a docker image of a simple nginx based reverse proxy server that I successfully use in my docker-compose.yml.

proxy:
    container_name: nginx-proxy
    restart: always
    image: jwilder/nginx-proxy
    ports:
      - 80:80
      - 443:443
    volumes:
      - certs:/etc/nginx/certs
      - vhost.d:/etc/nginx/vhost.d
      - html:/usr/share/nginx/html
      - /var/run/docker.sock:/tmp/docker.sock
    environment:
      - DEFAULT_HOST=site.ru
    networks:
      - main_network

In this container, I need to add only one line to nginx.conf, since it 'does not pass' a file larger than a certain size to my services that are behind it ...

Actually, how is it easier to do this?
add volume?
Maybe after the start just replace this config in the container?

Answer 1

The documentation says that it is enough to create a file *.confand put it in /etc/nginx/conf.d/a container.
You can build your image with such a modification, for example:

FROM nginx-proxy/nginx-proxy
RUN { \
      echo 'server_tokens off;'; \
      echo 'client_max_body_size 500m;'; \
    } > /etc/nginx/conf.d/my_proxy.conf

Answer 2

Add volume
Or add the whole /etc/nginx/ as a volume and remove the others
