无法在Google Cloud上部署Ubuntu 20.04 Docker容器

Question

Cloud Run error: Invalid argument error. Invalid ENTRYPOINT. [name: "gcr.io/{PROJECT_ID}/{SERVICE_NAME}@sha256:{HASH}"
error: "Invalid command \"/bin/sh\": fil
  e not found"
  e not found"
]....failed
Deployment failed

docker run --rm --publish 5000:5000 -e PORT=5000 -it gcr.io/{PROJECT_ID}/{SERVICE_NAME}@sha256:{HASH}

FROM ubuntu:20.04

COPY . /app
WORKDIR /app

RUN apt-get update \
    && DEBIAN_FRONTEND=noninteractive apt-get install -y python3 python3-pip \
    && pip3 install gunicorn Flask flask-cors

CMD exec gunicorn --bind :$PORT --worker-tmp-dir /dev/shm --timeout 900 wsgi:app

有人知道可能发生了什么吗？

我遇到了同样的问题。它似乎是断断续续的：在白天，我不能部署到云运行，但在晚上晚些时候，各种变通方法在大约一半的时间里发挥了作用。

我发现的最可靠的解决办法是不要依赖于CMD或EntryPoint中的/bin/sh或/bin/bash。它似乎在运行时存在/bin/sh，但在部署前Cloud Run测试容器时，它有时不存在。

在DockerFile中不是这样：

CMD exec gunicorn --bind :$PORT --workers 1 --threads 4 main:app

CMD ["/usr/bin/python3", "/app/run_gunicorn.py", "--workers", "1", "--threads", "4", "main:app"]

import os
import sys
from gunicorn.app.wsgiapp import run
port = os.environ['PORT']
sys.argv[-1:-1] = ['--bind', f':{port}']
print("sys.argv:", sys.argv)
run()
