Runc list does not show anything


I previously used docker version 17.05.
In this version, I could run container with docker run and pause it with docker-runc pause.

After upgrading to 18.09, docker-runc is changed to just runc and runc list shows nothing though there are sill running containers.

Is there any changes in the relation between containerd(or Docker) and runc?



Self reply to my question.
It seems directory to store container information for runc is changed.
Previously, it was /run/runc, but now it is /run/docker/runtime-runc/moby
After make a symlink to /run/runc, it works as expected.
