FROM centos
MAINTAINER codeyuaiiao<haijiao_yu@163.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
执行命令
docker build -f dockerfile -t mycentos:0.1 .

替换为版本7
将 FROM centos
替换为 FROM centos:7
