RaspberryPi webserver with nginx and docker only displays Welcome to nginx-CodePudding

I try to create a small webserver on my raspberry pi with docker. This is my docker-compose file:

version: "3.6"
services:
  web:
    image: nginx:latest
    ports:
      - "8080:80"
    volumes:
      - /home/pi/testData/code:/var/www/html
      - /home/pi/testData/site.conf:/etc/nginx/conf.d/site.conf
    depends_on:
      - php

  php:
    image: php:7.4-fpm
    volumes:
      - /home/pi/testData/code:/var/www/html

And this my site.conf

server {
    index index.html index.php;
    listen 80;
    server_name localhost;
    error_log /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /var/www/html;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(. \.php)(/. )$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

Inside of the folder /home/pi/testData/code is a file named index.php which just echos a Hello World. So this file will be mapped into the Docker Container into the path /var/www/html/ and inside of the site.conf is the root mentioned also to /var/www/html. I also checked if the files are really available inside of the nginx container - both are.

So as I understand it: If I put an index-file inside of the /var/www/html folder of my nginx docker container, then this file should be displayed if I call the IP of my Raspberry pi on Port 8080. But unfortunately I only receive the Welcome to Nginx Page.

Did I miss something or did I something wrong?

CodePudding user response：

Nginx will load configuration files found in /etc/nginx/conf.d/ and their names ends with .conf as suffix in alphabetical order.

Your configuration does have conflicting server name with the default configuration file of nginx. /etc/nginx/conf.d/default.conf you can check that by exec into nginx container and run nginx -t command to check the configuration for warnings and errors.

you should see something like:

[warn] 502#502: conflicting server name "localhost" on 0.0.0.0:80, ignored
nginx: [warn] conflicting server name "localhost" on 0.0.0.0:80, ignored

you should rename the default file to a something like default.conf.old or you can simply overwrite its contents with your configuration.
