# Create a base CentOS Docker image.

# This script is useful on systems with yum installed (e.g., building

把上面代码保存为本地create_dockerimages.sh,并执行

rpm -Uvh http://dl.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum -y install docker-io

./create_dockerimages.sh -y /etc/yum.conf centos6
