Docker: Store local files

This documentation is part of the Node.js guide. View the full guide here: How to use and deploy a Node.js app with Docker.

Welcome to the Stackhero documentation

Stackhero provides a ready-to-use Docker cloud CaaS (Containers as a Service) platform, designed for fast and reliable container deployments:

• Deploy to production with a single docker-compose up. There is no extra setup: just start your containers.
• Pick your own domain name, secured automatically with HTTPS (for example: https://api.your-company.com, https://www.your-company.com, or https://backoffice.your-company.com).
• Benefit from strong performance and robust security on private, dedicated infrastructure.
• Apply updates with one click for simple, low-effort maintenance.

You can have your containers live in production in about five minutes. Stackhero manages the infrastructure, updates, and security for you, so you can focus on delivering your applications. Read more about Docker CaaS cloud hosting.

If your Node.js app needs to store files (for example, user uploads), consider using an object storage service such as MinIO. An object storage service helps your application scale seamlessly while reducing potential issues.

If you prefer storing files locally, ensure you always use a Docker volume. Storing files directly in a container can lead to data loss. This boilerplate provides a volume mounted at /persistent for storing files safely.

Never store persistent data outside the /persistent directory unless you have created custom volumes and are certain of the configuration. Storing files outside /persistent will result in data loss!
