        *Dive deep into the world of Docker containers on Unraid!*
In Part 1, we explained what containers are, what problems they solve, how they are lightweight and isolated, and much more: https://youtu.be/y2Pk5j2l-gI 

In this second part of our Docker Demystified series, we tackle the most critical part of running apps on Unraid: *Data Management.* 

Many beginners struggle with losing configurations after an update or not knowing where files are actually stored. We explain exactly how to prevent that. You’ll learn:

*--The crucial difference between Persistent and Non-Persistent data.*
*--What actually lives inside the Docker Image vs. what stays on your server.*
*--Path Mappings explained simply: How to connect your Unraid storage to your containers.*
*--Troubleshooting tips for when your container can't "see" your files.*
*--How to safely remove containers without deleting your app data.*

*Chapters*
00:00 Understanding Docker Containers 
01:50 Persistent vs Non-Persistent Data
04:10 The Solution: Volume Mappings
05:50 Where Data Lives: The Appdata Share
09:09 Exploring the Container's Internal Filesystem
11:59 Path Mapping Logic (Host vs. Container)
14:55 Practical Demo: Setting Up a New Mapping
17:47 Troubleshooting & Verifying Data Persistence
20:43 Cleanup & Conclusion

*Takeaways*
--Docker containers are lightweight and share the host kernel.
--Understanding data management is crucial for effective container use.
--Persistent data survives container updates, while non-persistent data does not.
--Docker image files store non-persistent data and configurations.
--Path mappings are essential for containers to access host data.
--Container paths must be correctly mapped for communication between containers.
--Removing a container does not delete its app data by default.
--It's important to clean up orphaned app data after container removal.
--Docker networking will be discussed in the next part.
--Proper data management ensures smooth operation of Docker containers.
