Problem running multiple containers (layers?)

[Jaybau]

I would like to simultaneously run two similar containers from different repos.

 

In my example, I'm trying to run both qbittorrent and qbittorrent-hotio.  The container names, ports, appdata are different.  But I run into problems if I try to have both running at the same time (no problems if I have one of them stopped).

 

I don't know Docker all that well, but I suspect there's a "layer" that is being shared causing a conflict.

 

How do I run multiple containers that might share a layer?

Containers sharing layers should not be an issue. What kind of problems do you run into exactly? Does one just fail to start?
