Развертывание кода VS flask и docker

Question

как жизнь ... У меня проблема с развертыванием моего приложения в docker контейнере. У меня есть docker -compose.yml файл

version: "3"    
    services:   
      web:
        build: ./web
        ports: 
          - "5000:5000"
        links: 
          - db
      db:
        build: ./db

Итак, два других файла Docker один для Mon go БД и для Flask WebApp. Для базы данных Mon go просто:

FROM mongo:3.6.4

А для WebApp

# For more information, please refer to https://aka.ms/vscode-docker-python
FROM python:3.8

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
ADD requirements.txt .
RUN python -m pip install -r requirements.txt

WORKDIR /app
ADD . /app

# Switching to a non-root user, 
RUN useradd appuser && chown -R appuser /app
USER appuser

# During debugging, this entry point will be overridden.
CMD ["gunicorn", "--bind", "0.0.0.0:5000", "web.app:app"]

Структура моего рабочего пространства VS Code выглядит следующим образом:

Workspace
    --db
    ----Dockerfile
    --web
    ----app.py
    ----Dockerfile
    ----requirements.txt
    --docker-compose.yml

Я запускаю sudo docker - composer Построить без проблем ... Образ создан

запуск образа БД работает нормально, запуск образа WebAApp с помощью интерактивного запуска ... oups ... с этой ошибкой
