How can I find out which pod the directory belongs to?

General

OS: centos7
docker info
docker info
Containers: 62
 Running: 58
 Paused: 0
 Stopped: 4
Images: 73
Server Version: 18.06.3-ce
Storage Driver: vfs
Logging Driver: json-file
Cgroup Driver: cgroupfs

Today ，I find my /var usage is 100% ,and vfs dir is very large.

cd /var/lib/docker/vfs/dir
du -chs *
610M    035d5b02bc1860721e5a189da5c9c17790e4e0a1ae30b726603622b8e879624b

I try find “035d5b02bc1860721e5a189da5c9c17790e4e0a1ae30b726603622b8e879624b” which pod used it.

But I just find one info:

grep -R 035d5b02bc1860721e5a189da5c9c17790e4e0a1ae30b726603622b8e879624b /var/lib/docker/image/
/var/lib/docker/image/vfs/layerdb/sha256/2d64e1b446889adac417fbaa0f8df4e5c3c7c5e8d604c2fc34cd7bed2bc90f36/cache-id:035d5b02bc1860721e5a189da5c9c17790e4e0a1ae30b726603622b8e879624b

Then I can’t find any info :woozy_face:
like use docer ps | grep ID,docker images | grep ID and so on.
How can I do?
I just want which pod(k8s) use disk .
