Volumes and data
Containers can be recreated from images, but databases, user files and configuration require backup and restore tests.

A practical DataHouse guide to Docker, Docker Compose, volumes, backup, registry, monitoring and application deployment on VPS or cloud servers.
Docker runs business applications in repeatable environments on VPS, cloud servers or dedicated servers. A production setup also needs volumes, backup, image updates, monitoring, logs, firewall rules and a restore procedure.
A common good start is a VPS or cloud server with Docker Compose. It separates the application, database, cache, workers and helper services without requiring full Kubernetes orchestration from day one.
Containers can be recreated from images, but databases, user files and configuration require backup and restore tests.
Containerized applications often sit behind a reverse proxy. Check certificate, proxy headers, HTTPS redirects and mixed content.
Base images and dependencies need an update process with build, test, deploy and rollback.
A running process is not enough. Monitor HTTP endpoints, error logs, resource usage, restarts and backup status.
Use it as a technical checklist and connect it with the relevant diagnostic tools before or after a production change.
