常用其他命令
後臺啟動容器
#命令 docker run -d 映象名！ [root@lvshihao /]# docker run -d centos 757173133e8e73985f024dc7e0506f4ac773ce6ba1fbbce18584eda80dbc7603 [root@lvshihao /]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 757173133e8e centos "/bin/bash" 9 seconds ago Exited (0) 8 seconds ago optimistic_banach #問題docker ps,返現centos已經停止了 #常見的坑,docker容器使用後臺執行,就必須要有一個前臺程序，docker發現沒有應用，就會停止
檢視容器日誌
docker logs -f -t --tail 顯示的條數 容器ID #發現centos沒有日誌 #自己編寫一段shell指令碼,讓centos在後臺一直每一秒執行著輸出lvshihao的操作，這樣centos就不會立刻掛掉 docker run -d centos /bin/bash -c "while true;do echo lvshihao;sleep 1;done" [root@lvshihao /]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3ab34a21e1cc centos "/bin/bash -c 'while…" About a minute ago Up About a minute sharp_yonath #顯示日誌 -tf #顯示日誌 --tail number #要顯示日誌條數 [root@lvshihao /]# docker logs -tf --tail 3 3ab34a21e1cc 2021-08-14T01:52:57.239363667Z lvshihao 2021-08-14T01:52:58.243463010Z lvshihao 2021-08-14T01:52:59.249260645Z lvshihao
檢視容器中程序資訊
#命令 docker top 容器id [root@lvshihao /]# docker top 3ab34a21e1cc UID PID PPID C STIME TTY TIME CMD root 70857 70839 0 09:49 ? 00:00:00 /bin/bash -c while true;do echo lvshihao;sleep 1;done root 76932 70857 0 09:56 ? 00:00:00 /usr/bin/coreutils --coreutils-prog-shebang=sleep /usr/bin/sleep 1
檢視映象的元素據
#命令
docker inspect 容器id
#測試
[root@lvshihao /]# docker inspect 3ab34a21e1cc
