        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

I have the above configuration for nginx running inside docker. For some reason it keeps on showing the default nginx page.

Inside the container there is a file /etc/nginx/nginx.conf which includes all the *.conf from the conf.d directory but still unable to get my conf worked.

Then i tried copying my files into sites-available and sites-enabled folders still no luck.

Kindly help Thanks

There are three things we need to do to get nginx up and running.

1. Delete /etc/nginx/conf.d/default.conf during the build process.
2. Make an upstream directive to properly reference the php-fpm service.
3. Alter the nginx user's UID to match yours.

The most efficient solution is to create a Dockerfile that solves all three of these nginx issues and put it in docker-compose.yml 's nginx service definition. This config helps correct the nginx user and includes sites-enabled/.conf

# /etc/nginx/nginx.conf: Changes user to www-data and includes /etc/nginx/sites-enabled/*.conf
user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
  worker_connections  2048;
  multi_accept on;
  use epoll;
}

http {
  server_tokens off;
  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  keepalive_timeout 15;
  types_hash_max_size 2048;
  include /etc/nginx/mime.types;
  default_type application/octet-stream;
  access_log off;
  error_log off;
  gzip on;
  gzip_disable "msie6";
  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-available/*;
  open_file_cache max=100;
}

daemon off;

Both the previous nginx.conf and this Dockerfile should be stored in the same directory.

# <your-nginx-build-context>/Dockerfile
FROM nginx:latest

# The default nginx.conf DOES NOT include /etc/nginx/sites-enabled/*.conf
COPY nginx.conf /etc/nginx/
COPY symfony.conf /etc/nginx/sites-available/

# Solves 1
RUN mkdir -p /etc/nginx/sites-enabled/ \
    && ln -s /etc/nginx/sites-available/symfony.conf /etc/nginx/sites-enabled/symfony.conf \
    && rm /etc/nginx/conf.d/default.conf

# Solves 2
RUN echo "upstream php-upstream { server php:9000; }" > /etc/nginx/conf.d/upstream.conf

# Solves 3
RUN usermod -u 1000 www-data

CMD ["nginx"]

EXPOSE 80
EXPOSE 443

Make sure to update the nginx service definition in docker-compose.yml with something like:

web:
    build: ./nginx/Dockerfile
