Future with digital ocean kubernetes

[MislavSag]

Hi,

I am trying to use future package with kubernetes for the first time. I have succesfully installed kubernetes cluster with Rstudio server using steps described here:
https://pacha.dev/blog/2022/02/02/rstudio-on-kubernetes/

I can see my R studio in web browser, listening on http://localhost:8787/.

I don't understand how can I run R commands in parallel from local machine, using future?

I have to use plan(cluster) but how to connect to my cluster from local machine?
