dockerfile报错：“/bin/sh -c yum -y install“

主要错误ERROR: failed to solve: process “/bin/sh -c yum -y install vim” did not complete successfully: exit code: 1
主要是容器版本问题，推荐使用Centos7
比如我的dockerfile 文件

[root@localhost dockerfile]# cat mydockerfile-centos FROM centos:7     #看这里 版本是7 MAINTAINER jiangyalun<123456@qq.com>  ENV MYPATH /usr/local    WORKDIR $MYPATH  RUN yum -y install vim RUN yum -y install net-tools  EXPOSE 80  CMD echo $MYPATH CMD echo "----end----" CMD /bin/bash
