WordPress Deployment Overview¶

Prerequisites¶

The following configuration parameters are required for the application to function correctly:

FQDN of the final panel on hostkey.in domain¶

Domain name template for application access:

File and Directory Structure¶

Main directories used in the system:

• /root/wordpress — project working directory and Docker Compose configuration file.

• /data/nginx/ — Nginx configuration files.

• /data/nginx/user_conf.d/ — custom virtual host configurations.

• /data/wordpress — web application content (WordPress files).

Application Installation Process¶

Deployment is performed by creating the necessary directories, generating Nginx and Docker Compose configuration files, and then starting the container environment using the docker compose up -d command. The application uses official WordPress and MariaDB images.

Docker Containers and Execution¶

The application is deployed as a set of three containers:

mariadb¶

• Image name: docker.io/bitnami/mariadb:latest

• Restart policy: unless-stopped

• Volumes: mariadb_data:/bitnami/mariadb

• Environment variables:

  • MARIADB_USER=wordpress

  • MARIADB_DATABASE=wordpress

  • MARIADB_PASSWORD={password}

  • MARIADB_ROOT_PASSWORD={password}

wordpress¶

• Image name: docker.io/wordpress:php8.2-fpm

• Restart policy: unless-stopped

• Ports: 127.0.0.1:9000:9000

• Volumes: /data/wordpress:/var/www/html

• Environment variables:

  • MYSQL_ROOT_PASSWORD={password}

  • WORDPRESS_DB_PASSWORD={password}

  • WORDPRESS_DB_HOST=mariadb

  • WORDPRESS_DB_USER=wordpress

  • WORDPRESS_DB_NAME=wordpress

nginx¶

• Image name: jonasal/nginx-certbot:latest

• Volumes:

  • nginx_secrets:/etc/letsencrypt

  • /data/nginx/user_conf.d:/etc/nginx/user_conf.d

  • /data/wordpress:/var/www/html

Application Update¶

Updates are performed via the command:

docker compose pull && docker compose up -d

Permissions Settings¶

To ensure security and correct service operation, the following permissions are set on directories:

• /data directory and subdirectories: owner root, group root, access mode 0640 or 0755.

• Configuration files in /data/nginx/: owner root, group root, access mode 0644.

• /root/wordpress directory: owner root, group root, access mode 0644 (for files) or 0755 (for directories).

Configuration Files and Data Location¶

Available Ports for Connection¶

• 80 — HTTP (for redirection and Certbot verification).

• 443 — HTTPS (primary access port for the website).

• 9000 — PHP-FPM (available locally on the host via 127.0.0.1).

Starting and Stopping the Application¶

Container management is performed from the /root/wordpress directory:

• Start:

  docker compose up -d
  

• Stop:

  docker compose down
