master：192.168.1.14
linux环境
uname -a
Linux master.localhost.com 3.10.0-514.10.2.el7.x86_64 #1 SMP Fri Mar 3 00:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
1.安装docker
yum install libdevmapper* -y
yum install docker -y
2、启动docker
systemctl start docker.service
systemctc enable docker
3、设置docker 镜像源加速器
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://ef017c13.m.daocloud.io
注：初次会生成/etc/docker/daemon.json 文件，并写入{“registry-mirrors”: [“http://48b042ae.m.daocloud.io“]} 配置参数。
cat /etc/docker/daemon.json
{“registry-mirrors”: [“http://ef017c13.m.daocloud.io“],
“live-restore”: true
}
下载registry镜像
docker pull registry
4、启动registry容器
docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry
5、配置本地deamon.json文件，添加如下参数：
“insecure-registries”:[“192.168.1.14:5000”] #该参数解决了 http: server gave HTTP response to HTTPS client问题
cat /etc/docker/daemon.json
{“registry-mirrors”: [“http://ef017c13.m.daocloud.io“],
“insecure-registries”: [“192.168.1.14:5000”],
“live-restore”: true
}
6、官网拉取测试镜像
docker pull redis
7、测试镜像打标签
docker tag redis 192.168.1.14:5000/localredis:01 #注库名不能有大写字母
8、上传到本地仓库
docker push 192.168.1.14:5000/localredis:01
9、删除本地镜像
docker rmi 192.168.1.14:5000/localredis:01
10、通过http api访问下
curl 192.168.1.14:5000/v2/_catalog
{“repositories”:[“localredis”]}
curl 192.168.1.14:5000/v2/localredis/tags/list
{“name”:”localredis”,”tags”:[“01”]}
11、拉取本地仓库镜像（其他节点需要配置/etc/docker/daemon.json,按照5配置）
docker pull 192.168.1.14:5000/localredis:01
12、验证是否下载：
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
192.168.1.14:5000/localredis latest 83d6014ac5c8 Less than a second ago 183.6 MB
192.168.1.14:5000/localredis 01 83d6014ac5c8 Less than a second ago 183.6 MB
