A simple Nginx proxy for PHP-FPM

This image is based on the latest Nginx docker image and includes additional functionality so that it can easily be set up as a PHP-FPM proxy for a container within the same Docker stack.

LISTEN_PORT	The port Nginx will listen on	80
DOCUMENT_ROOT	The path to the root of the application	/var/www/app

Static files

If your application has to serve static files, this can be achieved following the example illustrated in the docker-compose.yml below:

services:
  webserver:
    image: hercdottech/docker-nginx-fpm-proxy:latest
    environment:
      LISTEN_PORT: 80
      DOCUMENT_ROOT: /var/www/app
      CONTAINER_NAME: php-fpm
      CONTAINER_PORT: 9000
    ports:
      - '8080:80'
    volumes:
      - app-files:/var/www

  php-fpm:
    image: php:8.4-fpm-alpine
    volumes:
      - app-files:/var/www

volumes:
  app-files:

If you mount an empty volume into a directory in the container in which files or directories exist, these files or directories are propagated (copied) into the volume. Similarly, if you start a container and specify a volume which does not already exist, an empty volume is created for you. This is a good way to pre-populate data that another container needs.
