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国旗：

SHARED SIZE 是图像与另一个图像共享的空间量（即它们的公共数据）
UNIQUE SIZE 是仅由给定图像使用的空间量
SIZE是图像的虚拟大小，它是的总和SHARED SIZE与UNIQUE SIZE

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：
