Using Rstudio Server with docker

On the host machine

Assuming you already have docker installed, run the below code in a terminal on the host machine.

docker pull rocker/rstudio
docker run --rm -p 8787:8787 -e PASSWORD="password" rocker/rstudio

The default user name is “rstudio”. If you want to set the user name, add -e USER="user" to the command above.

As easy as that. To make the image usable we would have to create a new dockerfile based on this image and add run commands that install packages within R. For example,

from rocker/rstudio
RUN R -e "install.packages('tidyverse')"

The base armr dockerfile shows how to do this with an install script that reads a requirements.txt file - much quicker than installing each package individually. For saving work, you’ll also need to add a volume tag to the docker run command, e.g.,

docker run --rm -v $(pwd):home/user/ -p 8787:8787 -e USER="user" -e PASSWORD="password" rocker/rstudio

On the external machine

To access from another computer on the network, open a browser and navigate to hostname:877, where hostname is the hostname of the computer running the container. This can be found by running hostname on it from the terminal (Linux only). If you want to access Rstudio server on the go, away from home, then you will need to do the following.

• Issue a static IP address to the host computer, most easily done using your router
• Set up port forwarding to forward port 8787 from the static IP to the outside world
• Read up on security settings in Rstudio server and implement them! These are likely to include IP whitelisting, certificate only authentication, banning IP addresses after several failed attempts (see fail2ban) and more
