I have successfully created a 5-node k3s RPi4 cluster, installed and am running RStudio in a container (image pulled from docker pull ghcr.io/rocker-org/rstudio:4.3.1@sha256:ae264981a9884adc0b15c44018e0e2d5d08cff54c909f732755242d81b6455ba). I am able to install and load the "parallel" and "foreach" packages, but I am only able to access one node when running RStudio.
What do I need to do to access all cluster nodes when running RStudio?
