java - How can I properly self-host my Spring Boot app on my computer?

Question

I can't connect remotely to my SB app that I want to self-host

Introduction

I made a Spring Boot app with a 'my-sql' container that I want to share outside my home network to test it with some friends. The app works locally but I want to use it outside my network.

I have never, ever, deployed an app and I have little knowledge on this matter and I want to do it properly to avoid problems that I won't be able to handle myself.

What have I done so far

• I tried opening the 8080 port on the firewall for any connection
• I added my public ip in the application.properties with port 8080
• Used 0.0.0.0 to listen to any connection to 8080 as in this solution
• Load the app to Heroku (success) and self-host the 'my-sql' (that one is another question)

Problem

None of these solutions above worked for me

Answer 1

This is a network-related question. However, you need to have a static IP provided by your ISP first. Then you need to configure your network gateway to forward requests to your application.
