docker-compose docker nginx php

You need to mount same volumes for both PHP and Nginx docker image.

version: '3'
services:
  nginx:
    image: nginx:alpine
    volumes:
      - ./app:/app
      - ./nginx-config/:/etc/nginx/conf.d/
    ports:
      - 80:80
    depends_on:
      - php
  php:
    image: php:7.3-fpm-alpine
    volumes:
     - ./app:/app

in the above compose file, code is placed under app folder in the host.

Tree

├── app
│   ├── helloworld.php
│   └── index.php
├── docker-compose.yml
└── nginx-config
    └── default.conf

You Nginx config should use docker service network to connect with php-fpm container.

server {
    index index.php index.html;
    server_name php-docker.local;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /app/;

    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;
    }
}

Or you can try the working example from Github.

git clone https://github.com/Adiii717/dockerize-nginx-php.git
cd dockerize-nginx-php;
docker-compose up

Now open the browser

http://localhost/helloworld.php
