WordPress with MySQL Docker Application

This application deploys WordPress with MySQL as the database backend using Docker containers. The setup includes persistent storage for both the WordPress files and the MySQL database.

Prerequisites

To run this application, you need:

• Docker Engine (version 20.10.0 or newer)
• Bash shell environment
• 1GB+ of free RAM
• 1GB+ of free disk space
• Internet connection to pull Docker images

What the Application Does

This application sets up:

1. A WordPress instance that serves as a content management system
2. A MySQL database that stores WordPress data
3. Persistent volumes to maintain data between restarts
4. A dedicated network for secure inter-container communication

Virtual Networks

• wordpress_network: A bridge network for communication between the WordPress and MySQL containers. This network allows the containers to reference each other by container name instead of IP addresses.

Named Volumes

• wordpress_data: Stores WordPress files, themes, plugins, and uploads
• db_data: Stores MySQL database files

These volumes ensure data persistence across container restarts and application updates.

Container Configuration

MySQL Container

• Image: mysql:5.7
• Container name: db
• Environment variables:
  • MYSQL_ROOT_PASSWORD: Root password for MySQL
  • MYSQL_PASSWORD: Database password for the WordPress user
  • MYSQL_USER: Database user for WordPress (jawad1)
  • MYSQL_DATABASE: Database name for WordPress (cloud_database)
• Volume mounted: db_data:/var/lib/mysql
• Network: wordpress_network
• Restart policy: unless-stopped (automatically restarts if the container fails)

WordPress Container

• Image: wordpress:latest
• Container name: wordpress_app
• Environment variables:
  • WORDPRESS_DB_HOST: Database hostname (db)
  • WORDPRESS_DB_USER: Database username (jawad1)
  • WORDPRESS_DB_PASSWORD: Database password (jawad@password123)
  • WORDPRESS_DB_NAME: Database name (cloud_database)
  • WORDPRESS_CONFIG_EXTRA: Additional WordPress configuration
• Port mapping: 8080:80 (exposes WordPress on port 8080)
• Volume mounted: wordpress_data:/var/www/html
• Network: wordpress_network
• Restart policy: unless-stopped (automatically restarts if the container fails)

Usage Instructions

Preparing the Application

Run the prepare script to download Docker images:

chmod +x prepare-app.sh
./prepare-app.sh

Running the Application

Start the containers with:

chmod +x start-app.sh
./start-app.sh

After starting, WordPress will be available at http://localhost:8080

The first load may take some time as WordPress initializes the database and sets up the environment.

Stopping the Application

Stop the running containers without removing data:

chmod +x stop-app.sh
./stop-app.sh

Removing the Application

To completely remove the application, including all data:

chmod +x remove-app.sh
./remove-app.sh

Warning: This will delete all your WordPress data and MySQL databases!

Accessing the Web Application

After starting the application, access WordPress through your web browser at:

http://localhost:8080

The first time you access this URL, you'll be guided through the WordPress setup process where you can create an admin account and configure your site.
