Sharing folders from container to container?

I’m trying to share folders and files from one container to another. I have found lots of guides on how to do a shared volume for containers. Problem is that I already have the containers installed and running. Like Sonarr, Transmission and Emby.

Do I need to start from the beginning and redo all my containers or can I share them some how?

The only possible answer with the provided details is: it depends!

Show us what you do, and we can tell you what needs to be done differently :wink:
