多個 filesyste 啟動 acc code ppi -- ike ces 常用命令如下表:
選項 描述
ls 列出容器
inspect 查看一個或多個容器詳細信息
exec 在運行容器中執行命令
commit 創建一個新鏡像來自一個容器
cp 拷貝文件/文件夾到一個容器
logs 獲取一個容器日誌
port 列出或指定容器端口映射
top 顯示一個容器運行的進程
stats 顯示容器資源使用統計
stop/start 停止/啟動一個或多個容器
rm 刪除一個或多個容器
1、ls - 列出容器
只列出正在運行的容器:
[root@localhost ~]# docker container ls
列出所有容器,包括已停止的:
[root@localhost ~]# docker container ls -a
inspect - 查看一個或多個容器詳細信息:
[root@localhost ~]# docker container inspect nginx01
......
2、exec - 在運行容器裏執行命令
在容器裏執行命令:
[root@localhost wwwroot]# docker container run -d --name nginx04 -h nginx04 nginx
a44b757591db1ebd9146ec9245b742f755439d83637012f4a27de83e56b52153
進入容器終端:
[root@localhost wwwroot]# docker container exec -it nginx04 bash root@nginx04:/# hostname nginx04
查看主機名:
[root@localhost wwwroot]# docker container exec nginx04 hostname
nginx04
查看時間:
[root@localhost wwwroot]# docker container exec nginx04 date
Sun Aug 5 19:10:11 UTC 2018
[root@localhost wwwroot]#
3、cp - 拷貝文件或目錄到一個容器
拷貝文件到容器:
[root@localhost ~]# echo 123321 >> 123.txt [root@localhost ~]# cat 123.txt 123321 [root@localhost ~]# docker container cp 123.txt nginx04:/usr/share/nginx/html [root@localhost ~]# docker container exec -it nginx04 cat /usr/share/nginx/html/123.txt 123321 [root@localhost ~]# docker container exec -it nginx04 ls /usr/share/nginx/html/123.txt /usr/share/nginx/html/123.txt [root@localhost ~]# cd /usr/share/nginx/html -bash: cd: /usr/share/nginx/html: No such file or directory [root@localhost ~]#
4、logs - 獲取一個容器日誌
查看容器日誌:
查看容器的IP地址
[root@localhost ~]# docker container inspect -f ‘{{.NetworkSettings.IPAddress}}‘ nginx02
172.17.0.3
[root@localhost ~]# docker container inspect -f ‘{{.NetworkSettings.IPAddress}}‘ nginx01
172.17.0.2
[root@localhost ~]# docker container inspect -f ‘{{.NetworkSettings.IPAddress}}‘ nginx04
172.17.0.6
查看容器nginx02的日誌:
[root@localhost ~]# docker container ls|grep nginx02
a5e10362acc3 nginx "nginx -g ‘daemon of…" 25 hours ago Up 2 hours 0.0.0.0:88->80/tcp nginx02
[root@localhost ~]# docker container inspect -f ‘{{.NetworkSettings.IPAddress}}‘ nginx02
172.17.0.3
[root@localhost ~]# curl -I http://192.168.1.101:88
HTTP/1.1 200 OK
Server: nginx/1.15.2

5、port - 列出或指定容器端口映射
查看容器端口映射:
[root@localhost ~]# docker container port nginx02
80/tcp -> 0.0.0.0:88
6、top - 顯示一個容器運行的進程
查看容器運行進程:
[root@localhost ~]# docker container top nginx02
UID PID PPID C STIME TTY TIME CMD
root 3351 3335 0 00:56 ? 00:00:00 nginx: master process nginx -g daemon off;
101 3391 3351 0 00:56 ? 00:00:00 nginx: worker process
7、stats - 顯示容器資源使用統計
查看容器資源利用率:
[root@localhost ~]# docker container stats --no-stream nginx02
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
a5e10362acc3 nginx02 0.00% 1.383MiB / 1.566GiB 0.09% 26kB / 18.1kB 24.6kB / 4.1kB 0
8、export - 導出容器文件系統到tar歸檔文件
docker export name/id > name.tar
[root@localhost ~]# docker export -h
Flag shorthand -h has been deprecated, please use --help
Usage: docker export [OPTIONS] CONTAINER
Export a container‘s filesystem as a tar archive
Options:
-o, --output string Write to a file, instead of STDOUT
[root@localhost ~]# docker export nginx03 >nginx03.tar
[root@localhost ~]# docker export nginx03 -o test01
[root@localhost ~]# du -sh test01 nginx03.tar
106M test01
106M nginx03.tar
9、停止/啟動/刪除一個容器
restart/stop/start/rm -
[root@localhost ~]# docker container stop nginx02
nginx02
[root@localhost ~]# docker container rm nginx02
