Flask public site?

Question

Flask

Hey! The question is: app.run(host='0.0.0.0') - is the site visible on the Internet, if not, how can it be done on a laptop (laptop=server)?

Answer 1

app.run(host='0.0.0.0') will make Flask listen on port 80 on all IP addresses you have on your computer. The visibility of the site to the Internet depends on the configuration of your network and the services provided by your ISP.
If the laptop is connected to a router, then you need to configure port forwarding of the 80th port to the laptop on the router. In addition, make sure that the provider provides you with a "white" IP address (usually this is an additional service).

Answer 2

0.0.0.0 equates to 127.0.0.1, localhost. Substitute an interface that looks to the external network and get access from outside:
app.run(host='192.168.1.1')
