一.軟件環境
宿主機操作系統：CentOS Linux release 7.5
虛擬機工具：VMware® Workstation 10
應用容器引擎:Docker version 19.03.7
二.任務背景
所謂私有倉庫，也就是在本地（局域網）搭建的一個類似公共倉庫的東西，搭建好之後，我們可以將鏡像提交到私有倉庫中。這樣我們既能使用 Docker 來運行我們的項目鏡像，也避免從公共倉庫中來取來拿所暴露出去的風險；利用Docker Registry快速搭建私有鏡像倉庫。
三.操作步驟
倉庫地址：192.168.153.141
#下載registry鏡像

#創建registry容器並啓動
[root@docker docker]# docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000
