No URLs in mirrorlist

[Artio-Li]

使用命令构建镜像：
docker build --build-arg JDK_PKG=jdk-jdk-8u171-linux-x64.tar.gz --build-arg WEBLOGIC_JAR=fmw_12.2.1.4.0_wls_lite_generic.jar -t weblogic12014jdk8u171 .
然后会报如下错误：
[+] Building 6.0s (6/27)

百度了下说是centos 8 于2021年12月31日停止了源的服务，需要修改yum的源等等操作，但是我用的是mac，这个怎么解决？

在Dockerfile里添加
RUN cd /etc/yum.repos.d/
RUN sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
RUN sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

在Dockerfile里添加 RUN cd /etc/yum.repos.d/ RUN sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-* RUN sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

感谢解答，看来外部环境越来越复杂了，我需要重新测试Dockerfile了，可以暂时采用此操作解决

更改了这个还是不行欸 我是在Kali上搭建的

添加到Dockerfile的

# 解决libnsl包丢失的问题
RUN cd /etc/yum.repos.d/
#添加到这里
RUN cd /etc/yum.repos.d/
RUN sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
RUN sed -i 's|#baseurl=[http://mirror.centos.org|baseurl=http://vault.centos.org|g](http://mirror.centos.org%7Cbaseurl%3Dhttp//vault.centos.org%7Cg)' /etc/yum.repos.d/CentOS-*
