Let’s say you just want to have Joomla with its Mysql and also redis infrastructure ready.
And don’t want to bother setting it up manually for each services.

Just make a docker-compose.yaml with the following content and then start it up.

version: '3.1'

services:
  web:
    image: joomla
    restart: always
    links:
      - db:mysql
      - redis:cache
    ports:
      - "80:80"
    volumes:
      - "./html:/var/www/html"
      - "./php/php.ini:/usr/local/etc/php/php.ini"
    environment:
        JOOMLA_DB: ${MYSQL_DB}
        JOOMLA_DB_HOST: db
        JOOMLA_DB_PASSWORD: ${MYSQL_ROOT_PASSWORD}

  db:
    image: mysql:5.6
    ports:
      - "3306:3306"
    restart: always
    volumes:
      - "./mysql:/var/lib/mysql"
    environment:
        MYSQL_DATABASE: ${MYSQL_DB}
        MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}

  redis:
    image: redis
    container_name: cache
    ports:
        - "6379:6379"
    restart: always    

then create an .env file with the content for above parameters.

MYSQL_ROOT_PASSWORD=password # set to whatever here
MYSQL_DB=dbname # set approriate database name here

If you have an pre-compiled quickstart file, just extract it into `html` folder.

Then just start the docker with

docker-compose up -d

During install process at http://localhost/installation
just enter the password and db name credential similar to what have been defined in `.env` file.
