gunicorn.errors.HaltServer 同时部署到谷歌云运行 python 应用程序

Question

这是我的 dockerfile。我正在尝试使用以下两个命令将此图像部署到谷歌云运行

1. gcloud builds submit --tag gcr.io/smartshop-292203/data_science --timeout=20h0m0s
2. gcloud run deploy --image gcr.io/smartshop-292203/data_science --platform managed

我正在使用这个参考链接

https://cloud.google.com/run/docs/quickstarts/build-and-deploy#python

Dockerfile：

FROM python:3.8

# Allow statements and log messages to immediately appear in the Knative logs
ENV PYTHONUNBUFFERED True

# Copy local code to the container image.
ENV APP_HOME /app
WORKDIR $APP_HOME
COPY . ./

# update image and install cmake
RUN apt-get update 
RUN apt-get upgrade -y
RUN apt-get install cmake -y
RUN apt-get install libgl1-mesa-glx -y

# Install production dependencies.
RUN pip install -r requirements.txt

# command to run on container start
# CMD [ "python", "./app.py" ] 
# CMD exec gunicorn --bind :$PORT --workers 1 --threads 8 --timeout 0 main:app
CMD exec gunicorn --bind :8001 --workers 1 --threads 8 --timeout 1500 main:app
# CMD exec gunicorn main:app --bind 0.0.0.0:8080 --worker-class aiohttp.GunicornWebWorker
# CMD exec gunicorn --bind 0.0.0.0:8080 wsgi:main
# CMD ["/bin/bash"]

我遇到的错误：

        "Traceback (most recent call last):
    File "/usr/local/bin/gunicorn", line 8, in <module>
        sys.exit(run())
    File "/usr/local/lib/python3.8/site-packages/gunicorn/app/wsgiapp.py", line 58, in run

        raise HaltServer(reason, self.WORKER_BOOT_ERROR)
    gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>"

会有什么问题？ 请看一下

尝试使用--preload 运行gunicorn。您将看到完整的堆栈跟踪。应用创建步骤似乎有问题。

您还可以使用以下方式部署您的应用： gcloud beta run deploy - deploy
