What is the best method to keep scrapyrt open/active even after reboot

I have been exploring many options on how to keep scrapyrt open and active even after reboot, but I am unsure what is best. I was thinking of using immortal.run. I have used tmux, but it eventually kills the scrapyrt process after sometime. Not sure how long it persists. I have also tried without success to write a bash script to start scrapyrt within a tmux session (new or existing) if the scrapyrt process is not active. Is immortal.run a good option? Is a simple bash script and using crontab (for example: @reboot) possible? I am open to any option that will work. Please share an example. Thanks. (I am currently using Ubuntu 18.04 VM on Azure)

Here is an example of my attempt at writing a script in bash:

#!/bin/bash
if ! pgrep -x "scrapyrt" > /dev/null
then
	SESSION_NAME=coinSpider
	tmux has-session -t $SESSION_NAME 2>/dev/null
	if [ $? -ne 0 ]
	then
		tmux new-session -d -s $SESSION_NAME "$*"
	fi
	tmux attach -t $SESSION_NAME \; \
	send-keys -t 'scrapyrt -p 9080 -i 0.0.0.0' C-m \;
fi

There is wiki here that could contain useful info like this, otherwise it could go to readthedocs docs https://github.com/scrapinghub/scrapyrt/wiki/Deploy

That documentation has the deployment to ubuntu server marked as todo since 2016.
