Question

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构建成功，但docker运行失败，并显示错误

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

我查看了与此相关的答案import matplotlib.pyplot as plt, ImportError: libGL.so.1: cannot open shared object file: No such file or directory

import matplotlib.pyplot as plt

使用

import matplotlib
matplotlib.use("Agg")
import matplotlib.pyplot as plt

但是它对我不起作用。还查看了ImportError: libGL.so.1: cannot open shared object file: No such file or directory，但我没有Ubuntu作为基本映像，因此该安装对我来说不起作用，如答案中所列。

让我知道一种实现此目的的方法。

通过对dockerfile进行以下更改，我能够使docker容器运行

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

在不更新ubuntu环境的情况下无法运行。此外，将Docker映像创建为非交互式可以帮助跳过任何交互式命令行输入

由于libGl错误而无法运行Docker映像
