Configuring the Flask port with SERVER_NAME

Hi,

I'm trying to get the Flask server to run on a different port than the 
default of 5000.  The docs say that SERVER_NAME can be updated in the 
config to change this, but it doesn't appear to do so, even though when 
I print out app.config the SERVER_NAME is being set correctly.  Passing 
the port keyword arg to app.run() does work, however.

How can I configure the port via the config dict?

Thanks,

You could set the SERVER_NAME and then set a SERVER_PORT and then use 
those constants when you run the app:

SERVER_NAME = 127.0.0.1
SERVER_PORT = 5001

…

app.run(SERVER_NAME, SERVER_PORT)

Assuming you're running your app outside of the config, you'd need to 
import the app object and then call the config dictionary:

import app

app.run(app.config.get('SERVER_NAME'), app.config.get('SERVER_PORT'))

Hi,

Do you mean the port for the development server that you start with 
app.run() ? You can’t. The port number is a parameter to the run method, 
it is never taken from the config.

However your own code can look in the config before calling app.run()
