Amount of disk space used under ~/Library/Containers/com.docker.docker/ should shrink when deleting images and/or containers
Amount of disk space used under ~/Library/Containers/com.docker.docker/ doesn't shrink after deleting ~50 containers and ~141 images (out of a total of 194). My Docker.qcow2 was 41GB both before and after doing these deletions.
On the Diagnose & Feedback screen I see an error that looks relevant:
Diagnostic ID from "Diagnose & Feedback" in the menu.
I might not have this anymore since I had to do a factory reset in order to reclaim the disk space. After the factory reset, it is: 5F7A165B-83AC-4514-AFC4-DB53430D2E9D
a reproducible case if this is a bug, Dockerfiles FTW
Easy to reproduce by pulling some images, observing the size of Docker.qcow2, deleting the images and seeing that the size of Docker.qcow2 does not change. Let me know if more info is needed
page URL if this is a docs issue or the name of a man page
host distribution and version (OSX 10.10.x, OSX 10.11.x)
Steps to reproduce the behavior
pull several images
run a couple of containers
observe size of ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2
stop and delete all containers
delete all images
repeat step 3. Size has not shrunk despite there being no images or containers
