What are major WordPress Concerns you face when you use Docker in your application?

Heya,

For me the main concern would be Persistent Storage and Data Management:

-   **Use Docker volumes** to persist WordPress data such as uploads, plugins, themes, and configurations.
-   **Ensure regular backups** of persistent data to avoid data loss.
-   **Manage file permissions** carefully to avoid issues with data access and modifications.

Additionally, Database Management might be an issue as well. You’ll need to run the database in a separate container for better isolation and management.

Hey Adya,

Great question! For me, some of the main things to keep in mind would be:

1. Your MySQL database and wp-content directory are stored in Docker volumes to prevent data loss.
2. Docker can introduce performance overhead compared to just running your WordPress website on a Droplet directly.
3. Properly configure Docker networks to avoid connectivity issues and ensure secure communication between containers but also make sure to not expose your MySQL port to the public internet.
4. Keep your Docker images updated and secure.
5. Maintain consistent Docker configurations and environment variables across development, staging, and production environments.
6. Deploying WordPress with Docker can be complex. Use tools like Docker Compose or Kubernetes for better orchestration and scaling.

For a deeper dive into Docker, check out this free ebook. Additionally, this DigitalOcean tutorial on installing WordPress with Docker Compose is highly recommended.

Alternatively, you could also consider Kubernetes as well:

Hope this helps! Feel free to ask if you have more questions!
