我正在尝试构建 Centos Docker 映像来运行 NFIQ-2。它具有上面列出的 docker 文件。

当我运行它时，我似乎无法在存储库中找到软件包：
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
The command '/bin/sh -c yum update && yum upgrade -y' returned a non-zero code: 1
该软件包的维护者说 yum 为我获取的存储库缺少文件，但我如何在 docker 镜像中选择其他存储库？
答案1
更改更新命令就可以只运行 yum update：
FROM centos as builder
LABEL maintainer "[email protected]"
RUN sed -i 's/enabled=1/enabled=0/g' /etc/yum/pluginconf.d/fastestmirror.conf
ADD NFIQ2.tgz /
#RUN yum update && \
# yum upgrade -y
RUN yum update
RUN yum group install -y "Development Tools" && \
yum install -y cmake
RUN cd /NFIQ2/libOpenCV && \
cmake -D CMAKE_MAKE_PROGRAM=make /NFIQ2/OpenCV/
RUN make -C /NFIQ2/libOpenCV \
opencv_core opencv_ts opencv_imgproc opencv_highgui opencv_flann \
opencv_features2d opencv_calib3d opencv_ml opencv_video opencv_objdetect \

RUN make -C /NFIQ2/NFIQ2/
