Managing multiple WordPress environments—development, staging, and production—can be challenging. Using WordPress staging with Docker Compose enables developers to replicate production environments, test plugins, and deploy updates without affecting live sites. In this guide, we cover a multi-environment workflow, container configuration best practices, and techniques to streamline staging and deployment in 2025.

1. Why Use Docker Compose for WordPress Staging?

Docker Compose allows you to:

• Spin up isolated containers for each environment.
• Version control environment configurations.
• Quickly replicate staging environments locally or on remote servers.
• Standardize workflows across development teams.

Key benefits:

• Repeatable deployments
• Reduced configuration drift
• Secure separation between dev, staging, and production

2. Folder Structure for Multi-Environment Workflow

A clear project structure ensures maintainability:

wordpress-project/
├─ docker/
│  ├─ dev/
│  │  └─ docker-compose.yml
│  ├─ staging/
│  │  └─ docker-compose.yml
│  └─ prod/
│     └─ docker-compose.yml
├─ wp-content/
├─ db-backups/
└─ .env

• docker/: Contains environment-specific Compose files.
• .env: Centralizes environment variables like DB credentials.
• wp-content/: Shared volume for themes, plugins, and uploads.

3. Sample docker-compose.yml for Staging

Here’s a staging Compose file with multi-service setup:

version: '3.8'

services:
  wordpress:
    image: wordpress:6.3-php8.2-fpm
    container_name: wp_staging
    env_file:
      - ../../.env
    ports:
      - "8081:80"
    volumes:
      - ../../wp-content:/var/www/html/wp-content
    depends_on:
      - db

  db:
    image: mysql:8.0
    container_name: wp_db_staging
    environment:
      MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASSWORD}
      MYSQL_DATABASE: ${DB_NAME}
      MYSQL_USER: ${DB_USER}
      MYSQL_PASSWORD: ${DB_PASSWORD}
    volumes:
      - ../../db-backups:/var/lib/mysql

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    container_name: wp_pma_staging
    ports:
      - "8082:80"
    environment:
      PMA_HOST: db

Notes:

• Each environment (dev, staging, prod) should have unique ports and container names.
• Volumes allow sharing plugins/themes while isolating databases.

4. Using Environment Variables for Multi-Environment Control

.env file example:

DB_ROOT_PASSWORD=StrongRootPassword123!
DB_NAME=wp_staging
DB_USER=wpuser
DB_PASSWORD=SecurePass2025

• Centralizes sensitive data for all environments.
• Avoid hardcoding passwords in Compose files for security.
• Combine with Docker Secrets in production for best practices.

---

5. Network Isolation Between Environments

Define separate networks per environment to prevent cross-contamination:

networks:
  staging_network:
    driver: bridge

services:
  wordpress:
    networks:
      - staging_network
  db:
    networks:
      - staging_network

Best practices:

• Dev network: local testing only.
• Staging network: isolated for QA.
• Production network: secured, minimal access.

---

6. Backup and Restore Strategy for Staging

Regular backups prevent data loss:

docker exec wp_db_staging sh -c 'exec mysqldump -uroot -p"$DB_ROOT_PASSWORD" $DB_NAME' > db-backups/staging.sql

• Automate backups via cron jobs.
• Test restore procedures regularly.
• Use volume snapshots for wp-content.

---

7. Deploying Updates Safely in Staging

• Pull new WordPress or plugin updates in staging first.
• Test thoroughly before deploying to production.
• Use separate Git branches for dev/staging/prod and merge only after QA approval.

---

8. Security Considerations in Staging

Apply Docker security tips from our previous post:

• Run containers with non-root users.
• Limit exposed ports.
• Use secrets for credentials.
• Monitor containers and logs for anomalies.

Even staging environments can be targeted by attackers if misconfigured.

---

9. CI/CD Integration for Staging

Automate your multi-environment workflow:

• Use GitHub Actions or GitLab CI/CD.
• Spin up staging containers on push to staging branch.
• Run automated tests on WordPress plugins/themes.
• Notify teams of successful or failed deployments.

---

Conclusion

By implementing WordPress staging Docker Compose, developers can safely replicate production environments, test changes, and maintain a secure workflow across multiple environments. Combining multi-environment Docker Compose setups with Docker security tips ensures both operational efficiency and a hardened staging environment.

Quick Reference: Multi-Environment Checklist

Task	Staging Recommendation
Folder structure	Separate Compose files per environment
Ports	Unique per environment to avoid conflicts
Environment variables	Centralize in .env
Networks	Isolated bridge network per environment
Backups	Daily DB + wp-content snapshots
Updates	Apply first to staging, test, then prod
Security	Non-root users, secrets, monitoring
CI/CD	Automated deployment and tests
