WordPress Docker Automation Script

This script automates the setup of a new WordPress environment for a client using Docker. It creates a complete, isolated WordPress stack with a database, phpMyAdmin, and an SFTP server. The entire process is containerized, ensuring a clean and repeatable deployment for each new client. At the end it dumps all the credentials into a txt file.

Features

🏗️ Automated Setup: Quickly create a new WordPress instance for a client with a single command.

🐳 Dockerized Environment: Uses Docker Compose to manage a multi-container application, including WordPress, MySQL, phpMyAdmin, and SFTP.

🔐 Secure by Default: Automatically generates strong, unique passwords for the WordPress admin, MySQL database, and SFTP user.

📂 Isolated Directories: Each client's installation is stored in its own directory under /opt/elite-wp-packages, preventing conflicts.

⚙️ WP-CLI Integration: Installs and uses WP-CLI inside the container to automatically complete the WordPress installation.

📄 Credential Management: Saves all generated credentials to a credentials.txt file within the client's directory for easy access.

Prerequisites

• Docker: The script requires Docker and Docker Compose to be installed on your system.
• WordPress Package: A zipped WordPress package must be available at /root/wp.zip.
• Root Permissions: The script must be run as the root user or with sudo to perform directory creation and Docker commands.

How to Use

1. Place the Script: Save the provided script as automateWordPress.sh and place it in a convenient location.

2. Prepare the WordPress Zip: Ensure you have a clean WordPress installation zipped and placed at /root/wp.zip.

3. Run the Script: Execute the script from the command line. It will prompt you for a client name.

   sudo ./automateWordPress.sh

4. Enter Client Name: When prompted, enter a client name without spaces and in lowercase (e.g., client1, acme-corp).

The script will then:

• Create a directory for the client.
• Unzip the WordPress package.
• Create a docker-compose.yml file.
• Start all the Docker containers.
• Wait for the containers to be ready.
• Install WordPress using WP-CLI and the generated credentials.
• Save all access details to a credentials.txt file.

Post-Installation

After the script completes, you can find all the necessary access information in the credentials.txt file.

• WordPress Site URL: http://[client-name].elite04.com
• phpMyAdmin URL: http://[client-name].elite04.com:8080
• SFTP Access:
  • Host: Your server's public IP address
  • Port: 2222
  • Username: [client-name]sftp
• Credentials File Location: /opt/elite-wp-packages/[client-name]/credentials.txt

---

Managing the Containers

The script provides convenient commands for managing the containers for a specific client.

• Stop and Remove Containers:

  cd /opt/elite-wp-packages/[client-name]
  docker-compose down

• View Logs:

  cd /opt/elite-wp-packages/[client-name]
  docker-compose logs -f

---

Directory Structure

The script creates the following directory structure for each client:

/opt/elite-wp-packages/
└── [client-name]/
    ├── html/               # All WordPress files are here
    ├── docker-compose.yml  # Docker configuration for this client
    └── credentials.txt     # All generated credentials
