gunicorn.errors.HaltServer部署到Google Cloud时为python应用程序运行

如何解决gunicorn.errors.HaltServer部署到Google Cloud时为python应用程序运行

这是我的dockerfile。我正在尝试使用以下两个命令将该图像部署到运行的google cloud

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

我正在使用此参考链接

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？ 请看看

解决方法

尝试使用 gunicorn 运行 --preload。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法部署您的应用程序： gcloud beta run deploy - deploy
