One container many users

I’m very new to working with Shinyproxy and multiple containers, so please tolerate my ignorance. It seems to me that each time a user connects Shinyproxy starts a new container. Is this true? Is it possible to have a single container serving multiple users? In an ordinary workflow, my R application initialises by loading relatively big amount of data shared by numerous Shiny UI users on a single host. Running a single container per user is very prohibitive in terms of memory and time.

As far as i know, this is not possible.

Probably, this can be achieved with a kubernetes deployment and using/configuring the option to preload container images (which I think it is pre-pulled images from a private registry). More details here: https://www.reddit.com/r/kubernetes/comments/oeruh9/can_kubernetes_prepull_and_cache_images/
