I need to securely delete all persistent data abount containers and docker images. For example for a certain temporary container runned.

I mean secure deletion performed by tools like shred or srm, repeated overwriting zero ora random data on disk.

I suppose doing this manually could be deleterious and compromise docker's cache and layer system, at disk level everything should reside in the /var/lib/docker/* path but I'm not sure if running shred / srm in these paths could cause problems.
