在這之前呢，也寫過兩篇關於Docker基礎入門類的文章
Docker容器技術入門（一）
Docker容器技術入門（二）
很多人都感覺這文章這麼簡單、這麼基礎，可是別忘記了“萬丈高樓平地起”，如果少了這個平地址，你這高樓估計也起不了。所以，基礎是學習任何一門技術或者一個技術點的重中之重，也可以說是很關鍵的決勝點。
所以呢，今天，民工哥給大家總結了這20個Docker Command，願各位小夥伴在通往“玩轉Docker”路上不再無助!!!!
安裝完成docker容器服務之後，需要了解如何操作它？在shell命令行下直接輸入docker就可以查看幫助信息，如下。
[root@master ~]# docker
Usage: docker COMMAND
A self-sufficient runtime for containers
Options:
--config string Location of client config files (default "/root/.docker")

-l, --log-level string Set the logging level ("debug", "info", "warn", "error", "fatal") (default "info")
--tls Use TLS; implied by --tlsverify
--tlscacert string Trust certs signed only by this CA (default "/root/.docker/ca.pem")
--tlscert string Path to TLS certificate file (default "/root/.docker/cert.pem")

#從結果可以看出兩個容器的ID是一樣的，只是TAG改變了，類似於linux中文件與文件的硬鏈接一樣，其兩者的inode號相同。17、docker build
使用Dockerfile創建鏡像
常用參數如下：
- -f #指定要使用的Dockerfile路徑
- –label=[] #設置鏡像使用的元數據；

- –no-cache #創建鏡像的過程不使用緩存
- –pull #嘗試去更新鏡像的新版本
- -q #安靜模式，成功後只輸出鏡像ID
- –rm #設置鏡像成功後刪除中間容器
- –ulimit #Ulimit配置
