dockerdisk

dockerdisk: Print the disk usage of individual containers [-a] [-h]
                                                          [--sort {id,log,disk,total}]
                                                          [-r] [--initialize]
                                                          [--help]

optional arguments:
  -a, --all             Show all Docker containers, rather than just running
                        ones
  -h, --human           Print sizes in human readable format
  --sort {id,log,disk,total}
                        Value to sort by
  -r, --reverse         Sort results in descending order
  --initialize          Initialize Docker's btrfs volume to report sizes and
                        begin a scan (note: scan may take a few minutes)
  --help                Print usage

dockerdisk prints disk usage information about Docker containers on your system. In particular, it will report the amount of disk space taken up by container logs (stdout/stderr from the container itself) and the amount taken up exclusively by the container itself (and not the underlying image).

dockerdisk (currently) only works if Docker is running on BtrFS.

Before dockerdisk will be able to report on a container's btrfs disk usage, you will need to run:

dockerdisk --initialize

This will initiate a scan of the filesystem's metadata to determine the sizes of each subvolume. During the scan, the sizes reported by dockerdisk may be inaccurate.
