创建好私有仓库之后，就可以使用 docker tag 来标记一个镜像，然后推送它到仓库。例如私有仓库地址为 127.0.0.1:5000。
root@localhost registry]# docker tag httptest:v8.0 127.0.0.1:5000/myhub/ngtest:latest
[root@localhost registry]# ls
config.yml
[root@localhost registry]# docker image ls

注意事项
如果你不想使用 127.0.0.1:5000 作为仓库地址，比如想让本网段的其他主机也能把镜像推送到私有仓库。你就得把例如 192.168.100.100:5000 这样的内网地址作为私有仓库地址，这时你会发现无法成功推送镜像。
这是因为 Docker 默认不允许非 HTTPS 方式推送镜像。我们可以通过 Docker 的配置选项来取消这个限制，
Ubuntu 16.04+, Debian 8+, centos 7
对于使用 systemd 的系统，请在 /etc/docker/daemon.json 中写入如下内容（如果文件不存在请新建该文件）
{
"registry-mirror": [
"https://registry.docker-cn.com"
],
"insecure-registries": [
"192.168.100.100:5000"
]
}
注意：该文件必须符合
json规范，否则 Docker 将不能启动。
[root@localhost repositories]# cat /etc/docker/daemon.jsion
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
{
"dns" : [
"114.114.114.114",
"8.8.8.8"
],
"insecure-registries": [ #限制https 选项
"192.168.100.100:5000"
]
}
