Add Docker for a quick test environment

# Start with the php image containing an Apache server

FROM php:apache

# Enable the Apache module to rewrite requests, because we need it in a .htaccess

RUN a2enmod rewrite

# That's it. Everything else will be done by Docker Compose.

version: "3.9"

services:

  status:

    build: .

    volumes:

      # Mount the current directory as document root into the container.

      # This way, updates to the code are immediately also inside the container

      - .:/var/www/html

    ports:

      # Publish what is inside the container on port 80 outside the container on port 8080, but only

      # to 127.0.0.1 (i.e. localhost). This means you won't expose the status page to anyone else

      # except your own PC while working on it.
