我测试了官方的教程，是可以的。但是自己的老是部署失败。

以下是docker的日志：

这是我的Dockerfile：

# 使用官方 Python 轻量级镜像
# https://hub.docker.com/_/python
FROM python:3.8-slim


# 将本地代码拷贝到容器内
ENV APP_HOME /app
WORKDIR $APP_HOME
COPY . ./


# 安装依赖
RUN pip install Flask==1.1.2 gunicorn==20.1.0 xlsxwriter==1.2.8 sqlalchemy==1.3.17


# 启动 Web 服务
# 这里我们使用了 gunicorn 作为 Server，1 个 worker 和 8 个线程
# 如果您的容器实例拥有多个 CPU 核心，我们推荐您把线程数设置为与 CPU 核心数一致
CMD exec gunicorn --bind :80 --workers 1 --threads 8 --timeout 0 main:app

事实上，和官网的教程中给的Dockerfile一模一样，只是由于有excel和数据库需求，加了两个库。

以下是main.py的部分代码：

if __name__=='__main__':
    app.run(
        debug=True,
        host='0.0.0.0',
        port=80
    )

下面是我文件夹目录：

没有子文件夹

谢谢！
