部署私有Docker Registry和使用
环境
vmware虚拟机
Ip:192.168.190.139
Ip:192.168.190.140
Ip:192.168.0.122 registry
Docker 1.12.2
Docker 版本1.12.2 其它版本配置不同
[demo@node139 ~]$ docker version

创建文件
每台客户端机器都需要添加这个文件
[demo@node140 ~]$ sudo vi /etc/docker/daemon.json
添加内容如下：
{ "insecure-registries":["192.168.0.122:5000"] }
[demo@node139 ~]$ sudo systemctl daemon-reload
[demo@node139 ~]$ sudo systemctl restart docker.service
启动registry容器
在192.168.0.122机器上启动registry
docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry
接下来修改一个该镜像的tag。
如果加上版本号的话，下载的时候也要加上版本号，默认为latest
如docker tag gliderlabs/consul-server 192.168.0.122:5000/gliderlabs/consul-server:1.0 这样需要一个镜像打打两个标签，一个有版本号一个没有版本号，下载的时候不加版本号就是下载latest的镜像内容
如果下载的镜像有版本号那打标签时也要把版本号加上才可以格式 imagename:version(tag name)
[demo@node139 ~]$ docker tag gliderlabs/consul-server 192.168.0.122:5000/gliderlabs/consul-server
[demo@node139 ~]$ docker images
