In my previous blog post, I have shown you how to run your R-scripts inside a docker container. For many of the projects we work on here at STATWORX, we end up using the RShiny framework to build our R-scripts into interactive applications. Using containerization for the deployment of ShinyApps has a multitude of advantages. There are the usual suspects such as easy cloud deployment, scalability, and easy scheduling, but it also addresses one of RShiny’s essential drawbacks: Shiny creates only a single R session per app, meaning that if multiple users access the same app, they all work with the same R session, leading to a multitude of problems. With the help of Docker, we can address this issue and start a container instance for every user, circumventing this problem by giving every user access to their own instance of the app and their individual corresponding R session.

If you’re not familiar with building R-scripts into a docker image or with Docker terminology, I would recommend you to first read my previous blog post.
