Multiple Webtop containers for multiple Users

How can run multiple simultaneous webtops, each with its own Docker image. I would like multiple Anki user to work simultaneously

You would deploy a container per the user that wants to access it. Webtop isn’t designed for proper multi user support within the container. Really if you’re wanting something like that, look into kasm.

Thanks. I thought that since Linuxserver.io Webtop uses KASM that would be sufficient

It just use the kasmvnc client.
