docker 常用命令 system篇

1.查看docker 空間使用情況

[root@worker1 ~]# docker system df
TYPE                TOTAL               ACTIVE              SIZE                RECLAIMABLE
Images              3                   0                   319.9MB             319.9MB (100%)
Containers          0                   0                   0B                  0B
Local Volumes       1                   0                   156.5kB             156.5kB (100%)
Build Cache         0                   0                   0B                  0B

2.查看實時事件（例如容器創建，刪除等均會實時顯示）

[root@worker1 ~]# docker system events

3.查看docker 系統信息（同docker info）

[root@worker1 ~]# docker system info

4.docker清理(清理停止的容器，沒用容器使用的網絡，鏡像，緩存)

[root@worker1 ~]# docker system prune
WARNING! This will remove:
  - all stopped containers
  - all networks not used by at least one container
  - all dangling images
  - all dangling build cache

Are you sure you want to continue? [y/N] y
Total reclaimed space: 0B
[root@worker1 ~]#
