let a few services continuously running (daemon) using plumber.

Thanks for opening this. This is something I'm actively thinking about. I don't think the solution belongs in plumber, since R's forte is not load balancing and managing processes, but I have a poked around at a couple of other tools that can be used to accomplish at least some of these purposes. I'll get them written up shortly.

You can set the port as a command line argument to your bash script:

#!/bin/bash

port=${1:-9002}

kill $(ps aux | grep "$port" | grep plumb | awk '{print $2}')
R --vanilla -e "library(plumber); pr <- plumb('query.api.r'); pr\$run(port=$port)"

kill makes sure you don't get the "port already in use"-error - Sometimes the port will stay in use even after the actual process is shut down.

EDIT. Going through the documentation I realized that any of my solution is original. Removed most of the parts from the official documentation.

Between the above link and http://plumber.trestletech.com/docs/docker/, I'm calling this closed.
