Docker Volumes Explained | Persist Data Beyond Containers (Volumes vs Bind Mounts)

Containers are meant to be temporary — your data should not be.

In this video, I explain why containers lose data by default and how Docker volumes solve this problem in a clean, production-safe way.

You’ll learn:
→ why container data disappears when containers are removed
→ how Docker volumes store data outside the container lifecycle
→ the difference between volumes, bind mounts, and tmpfs
→ when to use volumes vs bind mounts (dev vs prod)
→ how named volumes make backups and reuse easier
→ how databases like MySQL keep data safe with volumes
→ a real workflow to stop, delete, and recreate containers without losing data

This is essential before running databases, stateful services, or production workloads in Docker.
