from my container.I am prompted to connect to http://127.0.0.1:8000 . On copying the address to Firefox I am getting the error:

 unable to connect. 

How can I connect to fastapi server ?

PS The git branch I am working from was developed by another colleague so I have little to no idea how was fastapi was set up inside the docker

Answer 1

You need to use the command

uvicorn main:app --reload --host 0.0.0.0

Answer 2

A workaround solution. Through on deploy app will have public address and webdriver.Remote can take it, in dev it is ok to run selenium locally.

test_my_web.py

import unittest

from selenium import webdriver
import os

from dotenv import find_dotenv, load_dotenv
from webdriver_manager.chrome import ChromeDriverManager

load_dotenv(find_dotenv())



class TestWebListAll(unittest.TestCase):
    def setUp(self) -> None:
        chrome_options = webdriver.ChromeOptions()
        if os.environ.get("LOCAL_DEV"):  # == 'True'
            self.url = 'http://127.0.0.1:8000/'
            self.driver = webdriver.Chrome(ChromeDriverManager().install())
        else:
            self.driver = webdriver.Remote(
                command_executor='http://localhost:4444',
                options=chrome_options
            )
            self.url = 'insert public addres'  #

    def tearDown(self) -> None:
        self.driver.quit()

    def test_(self):
        self.driver.get(self.url)
        print(self.driver.title)
