docker 建立私有仓库，24.205为镜像仓库所在主机

一.下载registry

#yum install -y python-devel libevent-devel python-pip gcc xz-devel

#python-pip install docker-registry

二.在所有docker宿主机上都执行以下操作

#vi /etc/sysconfig/docker

设置other_args=‘--insecure-registry 192.168.24.205:5000‘

#service docker restart

三.打开防火墙并启动仓库的容器

#iptables -A INPUT -p tcp --dport 5000 -j ACCEPT

#service iptables save

#docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry

四.tag并上传镜像

#docker tag d8b514ed80b5 192.168.24.205:5000/centos:tomcat

#docker push 192.168.24.205:5000/centos:tomcat

五.下载镜像

#docker pull 192.168.24.205:5000/centos:tomcat
