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
