1. Using Docker Compose

Docker Compose offers a simplified and reproducible method for deploying multi-container applications like Horde Webmail. Instead of manually installing and configuring each component (web server, database, PHP), Docker Compose automates the process using a docker-compose.yml file.

Explanation:

This approach leverages pre-built Docker images for each component, eliminating the need for manual installation and configuration. Docker Compose orchestrates these containers, ensuring they work together seamlessly. This method improves consistency, simplifies deployment, and allows for easy scaling. It is a quick way to learn How to setup Horde Webmail with Apache or Nginx.

Example docker-compose.yml file:

version: "3.8"
services:
  db:
    image: mariadb:10.6
    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
      HORDE_DB_NAME: horde_db
      HORDE_SERVER_NAME: webmail.example.com
      HORDE_SSL: "true" # Optional: Enables SSL (requires certs in the image or mounted volume)
    depends_on:
      - db
    volumes:
      - ./config:/var/www/html/horde/config #Persist config between container recreations

volumes:
  db_data:

Steps:

  1. Install Docker and Docker Compose: Follow the official Docker documentation for your operating system.
  2. Create a docker-compose.yml file: Save the above example to a file named docker-compose.yml. Important: Replace placeholder passwords and domain names with your actual values.
