一、实验环境

# cat Dockerfile

二、用Dockerfile打镜像

# docker build  -f Dockerfile   -t   yumrepo:latest   .

# docker images  

三、用镜像起一个仓库容器

# setenforce 0

# sed  -i  's/^SELINUX=.*/SELINUX=permissive/g'  /etc/selinux/config

# systemctl  stop firewalld

# systemctl disable firewalld

#  mkdir  /opt/yum  

#  mv  *.rpm     /opt/yum

# docker run  -it  -d    --name  LocalRepositry   -v  /opt/yum:/opt/yum  -p 80:80    yumrepo:latest

# docker ps   -a  

# docker logs   LocalRepositry 

# ss  -tan  | grep  -w  ":80"
