Create a Directory for Flarum

First, create a directory on your local machine where you’ll store the Docker Compose configuration and related data.

Create a docker-compose.yml File

In the flarum-docker directory, create a docker-compose.yml file with the following content:

version: '3.7'

services:
  flarum:
    image: flarum/flarum:latest
    container_name: flarum
    ports:
      - "8080:80"
    environment:
      - FORUM_URL=http://localhost:8080
      - DB_HOST=db
      - DB_NAME=flarum
      - DB_USER=flarum
      - DB_PASS=flarum_password
    volumes:
      - ./flarum_data:/flarum/app

  db:
    image: mariadb:10.5
    container_name: flarum_db
    environment:
      - MYSQL_ROOT_PASSWORD=root_password
      - MYSQL_DATABASE=flarum
      - MYSQL_USER=flarum
      - MYSQL_PASSWORD=flarum_password
    volumes:
      - ./db_data:/var/lib/mysql
