在這之前呢,也寫過兩篇關於Docker基礎入門類的文章
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,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,需要瞭解如何操作它?在shell命令列下直接輸入docker就可以檢視幫助資訊,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")
-D, --debug Enable debug mode
--help Print usage
-H, --host list Daemon socket(s) to connect to (default [])
-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")
--tlskey string Path to TLS key file (default "/root/.docker/key.pem")
