Python 应用程序给出通过 Docker 部署的错误

我有我正在部署的 python 应用程序。容器正在正确创建并且已启动并正在运行。但是服务器正在停止并抛出错误。

文件

FROM python:3.8

# set the working directory in the container
WORKDIR /usr/src/app

# copy the dependencies file to the working directory
COPY requirements.txt ./

# install dependencies
RUN pip install -r requirements.txt

# copy the content of the local src directory to the working directory
COPY . .

EXPOSE 8000

# command to run on container start

CMD ["python3", "apps/main.py", "start", "--config", "config.yml"]

我在日志中遇到的错误

Traceback (most recent call last):

有人可以解释一下我定义的 dockerfile 或 CMD 命令是否有任何问题。

第一次尝试将主机更新到 0.0.0.0 但不起作用。
