100G on docker, don't know were to start. overlay2 directory
Hello guys,
I move my docker from raspberry pi to a VM with Debian 11 about 6 month ago, and the usage space had been increasing like crazy.
I made a du to he directory and this was the result that matters:
/var/lib/docker/overlay2# du -shc ./* | grep G
1.3G ./1cc5bd64e4cdfbe9340538a0c59c13b51df3b68513870eb6c9203a85697e196b
87G ./7ce2ac508820e515b8d3060f15a6cba486cd11d33a9ae5434ee73a2b32370c0d
93G total
On the container, I have only a few container, that don't need space:
/var/lib/docker/overlay2# docker ps

This is the local dock user space, for config and some data bases.

How can I check the long directory names belong to container?
