docker run -t -i ubuntu /bin/bash
檢查本地是否存在制定的映象，不存在從公有倉庫下載
利用映象建立並啟動一個容器
分配一個檔案系統，並在只讀的映象層外面掛著一層可讀寫層
從宿主主機配置的網橋介面中橋接一個虛擬介面到容器中去
從地址池配置一個IP地址給容器
執行使用者指定的應用程式
執行完畢後容器被終止。

-t：Docker分配一個偽終端並繫結到容器的標準輸入上，
-i：讓容器的標準輸入保持開啟。
對於建立的bash容器，當使用exit命令退出之後，容器就自動處於終止狀態了，這是因為對於Docker容器來說，當執行的應用退出後，容器也就沒有繼續執行的必要了。
-d：讓Docker容器在後臺以守護狀（Daemonized）形式執行

docker save 儲存一個映象到一個歸檔檔案

docker save -o centoscommittest.tar centoscommittest:latest     // 歸檔centoscommittest:latest映象至centoscommittest.tar
