    Think the ideal solution will be to deploy 2 different containers using docker-compose, one for gunicorn and another one for test2.js nodejs app.

    But could run test2.js nodejs script after starting gunicorn service using below code by inserting "&" at the end of gunicorn line

    #!/bin/bash
set -e

python3 test1.py

gunicorn -b 0.0.0.0:8000 "app:app" --workers=1 --threads=10 --timeout=3600 &

node /home/test2.js

    By default, the next line is only executed after the previous one, but maybe the command ends before the port is active, so you can use a while to check that

    #!/bin/bash
set -e

python3 test1.py

gunicorn -b 0.0.0.0:8000 "app:app" --workers=1 --threads=10 --timeout=3600
#
check=1
#
while [ $check -eq 1 ]
do
  echo "Testing"
  test=$(netstat -nlt | grep "0.0.0.0:8000" &> /dev/null)
  check=$?
  sleep 2
done

node /home/test2.js

    Try this :

    #!/bin/bash
set -e

python3 test1.py

# wait 10 seconds, then run test2.js
{ sleep 10; node /home/test2.js; } &

gunicorn -b 0.0.0.0:8000 "app:app" --workers=1 --threads=10 --timeout=3600
