line with sudo command is keep iteration when started with pm2

!/bin/bash
cd /home/pi/dockertest
sudo -S <<< Adminpassword docker-compose up -d --scale chrome=2 --scale firefox=0

I want to add a script to pm2 to start the SeleniumGrid. So I have created .sh file with above code and added to pm2 with

pm2 start '/home/user/dockertest/startGrid.sh' --name SeleniumGrid

Docker & Grid is up now, but in pm2 monit console, I see the command keeps iterating over and over. How to prevent this?

enter image description here

-S in sudo allows input from pipes to be the password

so you need to remove -S from sudo:

#!/bin/bash
cd /home/pi/dockertest
sudo <<< 'Adminpassword docker-compose up -d --scale chrome=2 --scale firefox=0'

and if you really want it to take the password from a pipe:

#!/bin/bash
cd /home/pi/dockertest
sudo -S bash -c 'Adminpassword docker-compose up -d --scale chrome=2 --scale firefox=0'

Hope that helps
