描述
显示停靠盘的使用情况
使用
docker system df [OPTIONS]
备选方案
名字，简写 | 默认 | 描述 |
|---|---|---|
--format | 使用Go模板打印出漂亮的图像 | |
--verbose，-v | 假 | 显示空间使用情况的详细信息 |
父命令
命令 | 描述 |
|---|---|
docke系统 | 管理Docker |
相关命令
命令 | 描述 |
|---|---|
docke系统df | 显示docker磁盘使用情况 |
docker系统事件 | 从服务器获取实时事件 |
docke系统信息 | 显示系统范围的信息 |
docker系统修剪 | 删除未使用的数据 |
扩展描述
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。
实例
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
注意：网络信息未显示，因为它不占用磁盘空间。
