Python API inside a Docker container fails

[swarmt]

Describe the bug
Using the Python API example works perfectly in a virtual environment.
Fails when run in a docker container with a time out.
HTTPConnectionPool(host='172.17.0.1', port=63342): Max retries exceeded with url:

To Reproduce

import os
import pathlib as pl
import shutil

import pytest
from gcp_storage_emulator.server import create_server
from google.auth.credentials import AnonymousCredentials
from google.cloud import storage

import upload


@pytest.fixture
def mock_storage_client():
    """Google Cloud Storage emulator"""
    host = "localhost"
    port = 9023
    server = create_server(host, port, in_memory=True)
    server.start()
    os.environ["STORAGE_EMULATOR_HOST"] = f"http://{host}:{port}"
    yield storage.Client(credentials=AnonymousCredentials(), project="test-project")
    server.stop()
    del os.environ["STORAGE_EMULATOR_HOST"]


def test_upload_folder(mock_storage_client):
    """Test uploading a folder to Google Cloud Storage"""
    bucket_name = "test-upload-bucket"
    mock_storage_client.create_bucket(bucket_name)

Expected behavior
Bucket is created.

System (please complete the following information):

• OS version: macos / linux
