How to implement Flask Application Dispatching by Path with WSGI?

Question

I would like to use a single domain as a Staging Environment for multiple flask applications that will eventually run on their own domains.

Something like:

This worked for me:

Folder structure

DISPATCHER (folder)
   dispatcher.py

   app1 (folder)
       __init__.py

   app2 (folder)
       __init__.py

   app3 (folder)
       __init__.py

dispatcher.py

from flask import Flask
from werkzeug.wsgi import DispatcherMiddleware
from werkzeug.exceptions import NotFound

from app1 import app as app1
from app2 import app as app2
from app3 import app as app3

app = Flask(__name__)

app.wsgi_app = DispatcherMiddleware(NotFound(), {
    "/app1": app1,
    '/app2': app2,
    '/app3': app3
})

if __name__ == "__main__":
    app.run()

app1 to app3 __init__.py

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index_one():
    return "Hi im 1 or 2 or 3"

if __name__ == "__main__":
    app.run()

Working

python app.py

localhost:5000/app1 "Hi im one"
localhost:5000/app2 "Hi im two"
localhost:5000/app3 "Hi im three"

Another configuratiom

You can import another app, like app0 and add a menu to the apps, changing this with NotFound()
