基于底包创建新的镜像
由于项目依赖了OpenCV对图像进行处理，而且项目都是采用Docker部署的。目前公司提供的镜像仓库都没有可用的包，所以只能自己修改。
docker image pull xxx/xxx/xxxx/xxx:latest先查看镜像是否下载成功：
docker image lsdocker run xxx/xx/xxxx-public:latest /bin/bash安装OpenCV
sudo yum install -y cmake gccwget https://github.com/opencv/opencv/archive/4.5.1.zipunzip 4.5.1.zip解压安装包
cd opencv-4.5.1创建build目录
mkdir build进入 build 目录
cd build设置 make 参数
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..make
# 注：此步需要等待较长时间make installdocker export -o xxxx-opencv.tar CONTAINERIDdocker import xxxx-opencv.tar xxxx/xxx/xxx-opencv这样我们就大功告成啦，只需要将倒入的image上传到自己的镜像仓库就完成了。
