Deploying a WordPress site with Docker essentially implies running the WordPress (WP) application and Database in separate containers. Here’s how it works:
1. Install Docker: Before you can use Docker, you have to install the Docker Engine and Docker Compose. Both of these can be installed with a single command on most Linux distributions. \`\`\` curl -fsSL https://get.docker.com -o get-docker.sh sudo sh get-docker.sh \`\`\`
1. Create a Directory: Now you need to create a directory for your project, you can do this with the mkdir command, followed by the name of your project \`\`\` mkdir wordpress_docker && cd wordpress_docker \`\`\`
1. Create a Docker Compose File: Create a yaml file named “docker-compose.yaml” using your preferable text editor and paste in this example: \`\`\` version: ‘3.3‘ services: db: image: mysql:5.7 volumes: – ./db\_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL\_DATABASE: wordpress MYSQL\_USER: wordpress MYSQL\_PASSWORD: wordpress
wordpress: depends\_on: – db image: wordpress:latest ports: – “8000:80“ restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress WORDPRESS_DB_NAME: wordpress volumes: db\_data: {} \`\`\`1. Run Docker Compose: To begin your WordPress deployment, use the up sub-command, alongside the -d flag to run it in detached mode. \`\`\` docker-compose up -d \`\`\`
1. Access the WP Site: Open a web browser and navigate to `http://localhost:8000` you should see the WordPress setup page.
Remember to replace ‘wordpress’ and ‘somewordpress’ for environment values such as MYSQL_USER, MYSQL_PASSWORD with your respective usernames and passwords for securing your DataBase.
You should also back up the exported Database, as it’s a local database and data might get lost if the Docker container crashes.
That’s it! Your WordPress website should now be live, and you can begin the process of customization as per your project requirements.
