How to run shell command after gunicorn service? this is for docker enterypoint.sh file-CodePudding

Below is my docker enterypoint.sh file code

#!/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

I want to run test2.js nodejs app after gunicorn service starts because test2.js required to connect with localhost:8000. Please help me with a solution for this

CodePudding user response：

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
