Python - How to run multiple flask apps from same client machine

Question

from flask import Flask
app = Flask(__name__)

@app.route(\"/\")
def main(job_id):
         


        

Answer 1

Flask development server by default listens on port 5000 so when you run a Flask app without port number it will run on 5000.

You can run a number of Flask app on the same machine but with the different port numbers. Let's say your scripts names are script1.py and script2.py:

$ export FLASK_APP=script1.py
$ flask run --host 0.0.0.0 --port 5000

Open up a new terminal

$ export FLASK_APP=script2.py
$ flask run --host 0.0.0.0 --port 5001
