建構本地私有倉庫以及通過Docker用戶端互動
本文主要講述，如何建構私有倉庫，如何使用私有倉庫，如何通過docker http接口和私有倉庫互動，如何通過docker go用戶端和私有倉庫互動。
第一步建構私有倉庫
有較多的内容講述這部分内容，不再贅述，詳細見
私有倉庫· Docker —— 從入門到實踐 - yeasy
docker私有倉庫搭建與使用實戰
docker run --name registry -d -p 5000:5000 registry
測試
測試方案，将一個鏡像推送到私有倉庫上，把本地鏡像删除，然後再通過私有倉庫拉取鏡像
選取一個本地一個鏡像打上私有倉庫位址的tag
