+# 搭建一个私有的docker registry
+
+
+找一台docker host，然后运行 
+
+```
+docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:2
+```
+
+docker registry 绑定了到本地的80端口。 接下来我们配置DNS server，假如我们这台运行registry的机器地址是192.168.99.100,
+
+然后我们找到上次配置gitlab ci的那个dns container
+
+执行
+
+```
+docker exec -it dns-server /bin/sh
+```
+
+添加一条新的记录
+
+```
+/ # more /etc/dnsmasqhosts
+192.168.211.10 gitlab.example.com
+192.168.99.100 registry.example.com
+/ #
+```
+
+然后重启container
+
+```
+docker restart dns-server
+```
+
+最后我们去gitlab-ci服务器，ping一下
+
+
+```
+[vagrant@gitlab-ci ~]$ ping registry.example.com
+PING registry.example.com (192.168.99.100) 56(84) bytes of data.

+[vagrant@gitlab-ci ~]$
+```
+
+成功。
+
+
+# 测试
+
+在gitlab-ci服务器上，编辑
+
+创建一个文件
+
+```
+sudo vim /etc/docker/daemon.json
+```
+
+然后写入内容：
+
+```
+[vagrant@gitlab-ci ~]$ sudo more /etc/docker/daemon.json
+{ "insecure-registries":["registry.example.com:5000"] }
+[vagrant@gitlab-ci ~]$
+```
+
+从docker hub拉取一个busybox，然后打一个tag
+
+```
+docker pull busybox
+docker tag busybox registry.example.com:5000/busybox
+```
+
+然后push到我们的私有registry里
+
+```
+[vagrant@gitlab-ci ~]$ docker push registry.example.com:5000/busybox
+The push refers to repository [registry.example.com:5000/busybox]

+[vagrant@gitlab-ci ~]$
+```
+
+成功。
