仅当使用docker时，最大重试次数达到了请求网址的错误

Question

我在python flask_endpoint.py文件中发出一个HTTP请求，该请求请求一个URL，并且运行良好。

list_of_words = split_and_clean(question)
        url = "http://azure1.com:5000" + \
            "/model?q={0}".format(
                '+'.join(list_of_words).replace('&', '%26')
            )
        resp = requests.get(url).json()

但是，当我使用docker容器调用相同的端点时，出现此错误。

ConnectionError: HTTPConnectionPool(host='azure1.com', port=5000): Max retries exceeded with url: /model?q=what+is+this (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fe636384490>: Failed to establish a new connection: [Errno 110] Connection timed out',))

这是我使用的docker文件供参考

RUN python --version

RUN pip install -r requirements.txt


EXPOSE 5002


RUN ls -la /product_info/key_matching/data

WORKDIR /product_info/key_matching

ENTRYPOINT ["python"]
CMD [ "key_matching_endpoint.py" ]

然后使用

docker run -p 5002：5002 product_info
