Python 3.x Dockerize Django应用程序失败，错误为“/bin/sh:[蟒蛇3，：未找到”；

我的docker编写文件如下：

Django_2.2:
build:
  context: .
  dockerfile: Dockerfile_Build_Django
# Give an image name/tag
image: django_2.2:iot 
container_name: Django_2.2
depends_on: 
  - Django_Mongo_4.2.12
networks:
  sw_Django:
    ipv4_address: 192.168.110.12
ports:
  - 8000:80
restart: always
volumes: 
  - type: volume
    source: vol_django_codes
    target: /usr/src/app

FROM python:3.9.3-alpine3.13
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . .
RUN pip install -r requirements.txt
# CMD ["python","./IoTSite/manage.py","runserver","0.0.0.0:80"]
CMD python ./IoTSite/manage.py runserver 0.0.0.0:80

我的docker文件“Dockerfile\u Build\u Django”如下所示：

Django_2.2:
build:
  context: .
  dockerfile: Dockerfile_Build_Django
# Give an image name/tag
image: django_2.2:iot 
container_name: Django_2.2
depends_on: 
  - Django_Mongo_4.2.12
networks:
  sw_Django:
    ipv4_address: 192.168.110.12
ports:
  - 8000:80
restart: always
volumes: 
  - type: volume
    source: vol_django_codes
    target: /usr/src/app

FROM python:3.9.3-alpine3.13
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . .
RUN pip install -r requirements.txt
# CMD ["python","./IoTSite/manage.py","runserver","0.0.0.0:80"]
CMD python ./IoTSite/manage.py runserver 0.0.0.0:80

requirements.txt如下：仅1行

Django == 2.2.17

但当我运行“docker compose up”时，它失败了，出现以下错误

[root@Django]# docker logs Django_2.2 
/bin/sh: [python3,: not found
/bin/sh: [python3,: not found

我一直在寻找解决方案很长一段时间，并尝试了许多通过谷歌找到的修复，目前为止没有运气。任何帮助都表示感谢。

我觉得参与其中是浪费生命，因为根据指南/用户手册编码5分钟，然后故障排除数小时甚至数天…

如果它能帮助：

FROM python:3.8
ADD project /app
WORKDIR /app

#(for production only)
#RUN pip3 install --default-timeout=10 --no-cache-dir -r requirements.txt
RUN pip3 install --upgrade pip
RUN pip3 install -r requirements.txt

EXPOSE 80
CMD ["gunicorn", "project.wsgi:application", "--bind", "0.0.0.0:80", "--reload"]

我建议您使用gunicorn在production env中运行服务器。

是的，有时这是浪费生命……您是否也可以添加requirements.txt？通常，如果您遇到该错误，那么您的

CMD

看起来像是有JSON数组语法，但您的标点符号有一部分错误（例如，单引号而不是双引号）；请参见示例…，但这与您在问题中包含的文件不匹配。@Petronella，很抱歉延迟，requirements.txt已更新到帖子中。感谢分享，尽管我是gunicorn的新手。我会记住这一点。
