centos7搭建docker私有库

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
