WILT: MySQL as a separate service in a PHP app container

Another quick one. Was struggling to get a mysql service up and running alongside a PHP container for a quick migrate/ translate thing. Way to do this is to use the docker host host.docker.internal as the MySql host to access.

version: "3"
services:
  php:
    build:
      context: .
    ports:
      - "80:80"
    volumes:
      - ./src:/var/local-src
  mysql:
    image: public.docker.itc.griffith.edu.au/mysql:8.0
    container_name: mysql-server-80
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=<password>
      - MYSQL_DATABASE=<database>
      - MYSQL_USER=<username>
      - MYSQL_PASSWORD=<password2>
    ports:
      - "3306:3306"

{
  "host": "host.docker.internal",
  "port": 3306,
  "user": "<username>",
  "password": "<password>",
  "db": "<database>"
}
