Is it possible to connect a specific docker container in rstudio cloud? I have one in mind that I would be interested on @ https://hub.docker.com/r/vnijs/rsm-msba/ if feasible, how to proceed?
Running arbitrary Docker images is not a feature of RStudio Cloud.
What features from that image are you most interested in?
Mostly the pre-installed packages and control over package versions ... but also the ability to use Jupyter Lab if needed. I'd rather use Rstudio for everything but some instructors that use python prefer Jupyter for their classes.
We hadn't entertained the idea of customizable docker containers, but we have thought about hosting JupyterLab. If there is enough interest, we could bump that up the priority list. We also have plans for supporting package version management, but it would probably be good to connect and confirm that we can support what you are looking to do.
