如何解决Windows上的Docker容器未给出任何响应

大家好，您好，我是Docker的新手，在部署Flask应用程序时遇到很多问题。我的Dockerfile：

# For more information,please refer to https://aka.ms/vscode-docker-python
FROM ubuntu:20.04

EXPOSE 5000

# Keeps Python from generating .pyc files in the container
ENV PYTHONDONTWRITEBYTECODE 1

# Turns off buffering for easier container logging
ENV PYTHONUNBUFFERED 1

# Install pip requirements
RUN apt-get update && apt-get install -y python3-pip unixodbc-dev python3-dev
ADD requirements.txt .
RUN pip3 install -r requirements.txt
RUN pip3 install flask-restful
RUN pip3 install werkzeug

workdir /app
ADD . /app

# Switching to a non-root user,please refer to https://aka.ms/vscode-docker-python-user-rights
RUN useradd appuser && chown -R appuser /app
USER appuser

# During debugging,this entry point will be overridden. For more information,please refer to https://aka.ms/vscode-docker-python-debug
CMD ["gunicorn","--bind","127.0.0.1:5000","main:app"]

Docker-compose：

version: '3.4'

services:
  tutorial:
    image: tutorial
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - 5000:5000

main.py：

api.add_resource(Video,"/videos/<int:video_id>") 
if __name__=='__main__':
    app.run(host="127.0.0.1",port=5000,debug=False)

一个主要问题是，当容器在本地主机上本地运行时，我无法从容器中获得休养权。在我的docker日志中，我看到gunicorn在听port 5000

[2020-10-09 14:20:19 +0000] [1] [INFO] Starting gunicorn 20.0.4

[2020-10-09 14:20:19 +0000] [1] [INFO] Listening at: http://127.0.0.1:5000 (1)

[2020-10-09 14:20:19 +0000] [1] [INFO] Using worker: sync

[2020-10-09 14:20:19 +0000] [7] [INFO] Booting worker with pid: 7

但是根据终端的信息，我看到我的容器端口打开了。但是它没有绑定，因为它在docker-compose文件ports:- 5000:5000.中指定了

C:\Users\fele>docker ps
CONTAINER ID        IMAGE                                                                       COMMAND                  CREATED             STATUS              PORTS               NAMES
f3e0bfae76ec        containerregistr.azurecr.io/restvideoshop:1 "gunicorn --bind 127…"   5 hours ago         Up 33 seconds       5000/tcp            beautiful_chatterjee

此外，如果我打开Windows docker桌面并检查我的容器，我会看到一个端口以未绑定状态打开。

所以当我运行test.py

import requests

BASE="http://127.0.0.1:5000/"
data=[{"name":"Duke Nuken","views":1000,"likes":10},{"name":"Never Again","views":20,"likes":80},{"name":"Belarus","views":500,"likes":70}]

for i in range(len(data)):
    response=requests.put(BASE+"videos/"+str(i),data[i])
    print(response.json())

我在终端中看到以下日志：

requests.exceptions.ConnectionError: httpconnectionPool(host='127.0.0.1',port=5000): Max retries exceeded with url: /videos/0 (Caused by NewConnectionError('<urllib3.connection.httpconnection object at 0x02FB8C30>: Failed to establish a new connection: [WinError 10061] Es konnte keine Verbindung hergestellt werden,da der Zielcomputer 
die Verbindung verweigerte'))

任何人都可以提出建议并告诉我为什么我无法从容器中得到答复吗？我应该在docker-compose文件中进行任何其他配置还是为gunicorn设置一些其他代码吗？另一个问题与docker不直接相关，我计划在Azure容器实例中部署容器，因此是否需要在容器内使用Nginx还是Azure本身可以通过Nginx完成事情？预先感谢
