UPDATE: The instructions here are no longer necessary! Resizing the disk image is now possible right from the UI since Docker for Mac Version 17.12.0-ce-mac49 (21995).

If you are getting the error: No space left on device

Configuring the qcow2 size cap is possible in the current versions:

# my disk is currently 64GiB
