docker system df
命令显示有关docker守护程序使用的磁盘空间量的信息。
默认情况下,该命令只显示所使用数据的摘要:
$ docker system df TYPE TOTAL ACTIVE SIZE RECLAIMABLE Images 5 2 16.43 MB 11.63 MB (70%)Containers 2 0 212 B 212 B (100%)Local Volumes 2 1 36 B 0 B (0%)
可以使用-v, --verbose

Docker图像报告了以下事件:
delete
import
load
pull
push
save
tag
untag
Docker插件报告下列事件:
install
enable
disable
remove
Docker卷报告了下列事件:
create
mount
unmount
destroy
Docker网络报告了下列事件:
create
connect
disconnect
destroy
Docker守护进程报告下列事件:
reload
的--since
和--until
参数可以是Unix的时间戳,日期格式时间戳,或持续时间的字符串(例如去10m
,1h30m
)来计算相对于客户机的时间。如果您不提供该--since
选项,则该命令仅返回新事件和/或现场事件。支持的格式为日期格式时间戳包括RFC3339Nano,RFC3339, ,2006-01-02T15:04:05
,2006-01-02T15:04:05.999999999
,2006-01-02Z07:00
和2006-01-02
。如果您不提供a Z
或a ,客户端将使用本地时区+-00:00
时间戳结束时的时区偏移量。在提供Unix时间戳时,输入seconds [.nanoseconds],其中seconds是自1970年1月1日(午夜UTC / GMT)以来经过的秒数,不包括闰秒(又名Unix时代或Unix时间)和可选项。纳秒字段是一秒不到9位数字的一小部分。
过滤标志(-f
或--filter
)格式为“key = value”。如果你想使用多个过滤器,传递多个标志(例如 --filter "foo=bar" --filter "bif=baz"
)
多次使用相同的过滤器将作为OR处理; 例如--filter container=588a23dac085 --filter container=a8f7720b8c22
将显示容器588a23dac085 或容器a8f7720b8c22的事件
使用多个过滤器将作为AND处理; 例如--filter container=588a23dac085 --filter event=start
将显示事件容器容器588a23dac085 与事件类型是开始
目前支持的过滤器是:
容器(container=<name or id>
)
守护进程(daemon=<name or id>
)
事件(event=<event action>
)
图像 (image=<tag or id>
)
标签 (label=<key>
or label=<key>=<value>
)
网络 (network=<name or id>
)
插件 (plugin=<name or id>
)
类型 (type=<container or image or volume or network or daemon or plugin>
)
体积 (volume=<name or id>
)
如果格式 (--format
) 指定,则将执行给定的模板,而不是默认格式。Go的文本/模板包描述格式的所有细节。
如果格式设置为{{json .}}
事件作为有效的JSON行流。有关JSON行的信息,请参阅http://jsonlines.org/.
对于这个例子,您需要两个shell。
shell 1:侦听事件:
$ docker system events
外壳2:启动和停止容器:
$ docker create --name test alpine:latest top $ docker start test $ docker stop test
shell 1:(再次 .. 现在展示事件):

退出docker system events
命令,使用CTRL+C
...
您可以使用以下不同的时间语法,通过绝对时间戳或主机上的相对时间过滤输出:
