    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: your_root_password
      MYSQL_DATABASE: horde_db
      MYSQL_USER: horde_user
      MYSQL_PASSWORD: secure_password
    volumes:
      - db_data:/var/lib/mysql

  web:
    image: jakobroehr/horde-webmail:latest # Use a community-maintained Horde Docker image
    restart: always
    ports:
      - "80:80"
      - "443:443"
    environment:
      HORDE_DB_HOST: db
      HORDE_DB_PORT: 3306
      HORDE_DB_USER: horde_user
      HORDE_DB_PASSWORD: secure_password
