Python 3.x 由于libGl错误，无法运行docker映像

Dockerfile

FROM python:3.6.8
COPY . /app
WORKDIR /app
RUN pip3 install --upgrade pip
RUN pip3 install opencv-python==4.3.0.38
RUN pip3 install -r requirements.txt
EXPOSE 80
CMD ["python3", "server.py"]

requirements.txt

Flask==0.12
Werkzeug==0.16.1
boto3==1.14.40
torch
torchvision==0.7.0
numpy==1.15.4
sklearn==0.0
scipy==1.2.1
scikit-image==0.14.2
pandas==0.24.2

docker生成成功，但docker运行失败，出现错误

与

但这对我不起作用。也看了，但我没有Ubuntu作为基础图像，所以这个安装将不会为我工作，如答案中所列

让我知道一种方法来实现这一点。

我可以通过对docker文件进行以下更改来运行docker容器

FROM python:3.6.8
COPY . /app
WORKDIR /app
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update -y
RUN apt install libgl1-mesa-glx -y
RUN apt-get install 'ffmpeg'\
    'libsm6'\
    'libxext6'  -y
RUN pip3 install --upgrade pip

RUN pip3 install opencv-python==4.3.0.38
RUN pip3 install -r requirements.txt
EXPOSE 80
CMD ["python3", "server.py"]

解决libGl错误所需的行

RUN apt install libgl1-mesa-glx -y
RUN apt-get install 'ffmpeg'\
    'libsm6'\
    'libxext6'  -y

在未更新ubuntu环境的情况下无法运行。此外，将docker映像创建为非交互式有助于跳过任何交互式命令行输入

，因为

python:

映像基于Debian，链接问题中的

apt get install

应该可以工作。您需要显式选择一个

python:-alpine

image./bin/sh:apt-get:notfound命令'/bin/sh-c apt-get-install'ffmpeg''libsm6''libxext6'-y'返回了一个非零代码：127是我使用基于alpine的映像时得到的，或者不是。'/bin/sh-c apt-install libgl1 mesa glx'命令返回了一个非零代码：1与还有其他选择。

FROM python:3.6.8
COPY . /app

ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update -y
RUN apt install libgl1-mesa-glx -y
RUN apt-get install 'ffmpeg'\
