为什么要弄私有仓库，大多是为了速度，我们再私有仓库中的push和pull的速度是特别快的。
利用registry快速搭建
https://hub.docker.com/_/registry/
Run a local registry: Quick Version
$ docker run -d -p 5000:5000 --restart always --name registry registry:2
Now, use it from within Docker:
$ docker pull ubuntu
$ docker tag ubuntu localhost:5000/ubuntu
$ docker push localhost:5000/ubuntu
这是官方的一个小demo。下面是我自己的实践。
# 拉取registry2.0版本
[root@FantJ ~]# docker pull registry:2

# 上传到私有仓库
[root@FantJ ~]# docker push 127.0.0.1:5000/nginx
The push refers to a repository [127.0.0.1:5000/nginx]

[root@FantJ ~]#
缺点：没有可视化管理工具，私有仓库服务宕机造成麻烦,没有用户管理机制、没有操作的记录功能。
优点：搭建操作简单
利用harbor搭建
下载地址：https://storage.googleapis.com/harbor-releases/release-1.5.0/harbor-offline-installer-v1.5.1.tgz
wget https://storage.googleapis.com/harbor-releases/release-1.5.0/harbor-offline-installer-v1.5.1.tgz
tar zxvf harbor-offline-installer-v1.5.1.tgz
cd harbor
修改配置harbor.cfg
hostname = fantj.top:8888
http还是https啥的自己看着改
保存退出，直接运行install.sh
cd ..
./install.sh
注意一点：harbor默认会占用80端口，所以请确保你的80端口不被占用，那怎么修改呢？
修改配置docker-compose.yml（需要改端口再进行）
将80:80的第一个80改为自定义的端口号
我在这里改成8888端口。
然后运行install.sh
......
[Step 4]: starting Harbor ...
Creating network "harbor_harbor" with the default driver
Creating harbor-log
Creating redis
Creating registry
Creating harbor-db
Creating harbor-adminserver
Creating harbor-ui
Creating nginx
Creating harbor-jobservice
✔ ----Harbor has been installed and started successfully.----
Now you should be able to visit the admin portal at http://fantj.top:8888 .
For more details, please visit https://github.com/vmware/harbor .
好的，成功了，我们来访问一下。
默认账号密码：
admin
Harbor12345
如果想修改，去harbor.cfg修改。
[root@FantJ harbor]# docker ps

可以看到我们的进程和镜像都多了很多的以vmware开头的（harbor是vmware公司的开源工具）.
好了，开始push测试
[root@FantJ harbor]# docker tag docker.io/nginx fantj.top:8888/internet-plus/nginx
[root@FantJ harbor]# docker push fantj.top:8888/internet-plus/nginx
The push refers to a repository [fantj.top:8888/internet-plus/nginx]
Get https://fantj.top:8888/v1/_ping: dial tcp: lookup fantj.top: no such host
它提示需要用https请求才安全，解决方式有两种：
第一种：docker启动的时候添加对域名+端口的信任 --insecure-registry=xxxx.xx.xx.xx:8888
第二种：添加ssl证书,改天更新
Harbor重启
#docker-compose stop
# ./install.sh
