Launch WordPress with Docker Compose on SiteBay

Introduction to Docker and Docker Compose

Docker provides a way to run applications securely isolated in a container, packaged with all its dependencies and libraries. It’s like having a tiny, portable machine that has everything the application needs to run.

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. This is perfect for setting up environments like a WordPress site with a separate MySQL database.

Docker containers for WordPress and MySQL are readily available on Docker Hub, allowing for easy deployment.

Benefits of Docker for WordPress Pre-configured Solutions: No need to manually configure your server environment. Docker containers are ready to use once deployed. Simplified Updates: Updating WordPress or MySQL is as simple as pulling the latest Docker images. Isolation: Docker ensures that your applications and their environment remain isolated and do not interfere with the host system or other containers. Setting Up WordPress with Docker Compose Installing Docker and Docker Compose

First, ensure Docker and Docker Compose are installed on your SiteBay. Docker allows you to create and manage containers, while Docker Compose helps manage multi-container setups.

Deploying WordPress and MySQL

Create a Project Directory: Make a new directory for your WordPress project and navigate into it:

mkdir ~/wordpress_site && cd ~/wordpress_site

Compose File: Create a docker-compose.yml file in this directory. This file defines your WordPress and MySQL services. Remember to set your passwords for the WORDPRESS_DB_PASSWORD, MYSQL_ROOT_PASSWORD, and MYSQL_PASSWORD variables.

version: ‘3.3’

services: wordpress: depends_on: - db image: wordpress:latest volumes: - wordpress_data:/var/www/html ports: - “8000:80” restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: [Your_Password] WORDPRESS_DB_NAME: wordpress

db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: [Your_Password] MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: [Your_Password]

volumes: wordpress_data: db_data:

Launch Containers: From the project directory, start your containers:

docker-compose up -d

Access WordPress: After the containers start, access your WordPress site by visiting http://localhost:8000 in your browser.

Maintaining Your WordPress Site

Automatic Restarts: The restart: always policy ensures your containers automatically start upon system reboot.

Stopping Containers: To stop the containers, use docker-compose down in your project directory.

Updating WordPress: To update, simply pull the latest images and restart the containers:

docker-compose down docker-compose pull && docker-compose up -d

Conclusion

Using Docker and Docker Compose streamlines the deployment and management of WordPress sites on SiteBay. This approach not only simplifies initial setup but also facilitates ongoing maintenance and updates. For detailed Docker documentation, visit the official Docker and Docker Compose guides.
