The command df -h shows: If multiple containers started from the same exact image, the total size on disk for these containers would be SUM (size of containers) plus one image size (virtual size - size). I could easily change the disk size for one particular container by running it with --storage-opt size option: docker run --storage-opt size=120G microsoft/windowsservercore powershell Sadly, it does not help me because I need large disk size available during build You can get the detail volume information of a container by. answered Mar The total size of these images accumulated to around ~10GB.
