在Docker容器中安装OpenCV

Question

我在尝试Dockerise一个依赖于OpenCV的Python应用程序。我尝试了几种不同的方式，但是我一直在尝试运行该应用程序时... ImportError: No module named cv2。

这是我目前的Dockerfile。

FROM python:2.7

感谢张贴此。我遇到了同样的问题并尝试了你的解决方案，尽管它似乎安装了OpenCV，但它给我带来了一个与Python 6库相冲突的版本问题，所以我采取了不同的路线。我认为更简单的方法是在你的容器中安装Anaconda，然后添加OpenCV。我使用Python 2，以便获得安装我的整个Dockerfile OpenCvv就是：

FROM continuumio/anaconda 
EXPOSE 5000 

ADD . /code-directory 
WORKDIR code-directory 
RUN conda install opencv 

CMD ["python", "run-code.py"] 

这将从continuumio /蟒蛇Dockerfile安装蟒蛇，然后它会使用Anaconda安装OpenCV。如果你需要的话，还有一个Python 3的独立连续Dockerfile。

这是一个image，它是在Ubuntu 16.04上搭建的，使用Python2 + Python3 + OpenCV。您可以使用 docker pull chennavarri/ubuntu_opencv_python

拉这里的Dockerfile将安装OpenCV两个python2和python3在Ubuntu 16.04（在上述相同dockerhub回购提供），并设置相应的raw1394链接。

• 在你把这个Dockerfile目录，建立搬运工形象docker build -t ubuntu_cv .

• 一旦图像：从https://github.com/chennavarri/docker-ubuntu-python-opencv

      make -j4 && make install && ldconfig 
  
  # Set the appropriate link 
  RUN ln /dev/null /dev/raw1394 
  
  RUN cd ~/opencv 
  

  人们一些附加说明新开始与码头工人复制建成后，可以通过做检查docker images

  REPOSITORY TAG  IMAGE ID  CREATED    SIZE 
  
  ubuntu_cv latest 6210ddd6346b 24 minutes ago  2.192 GB 
  

• 可以启动泊坞窗容器作为docker run -t -i ubuntu_cv:latest
