# Resize Boot2Docker disk volume

Boot2Docker VirtualBox VM is limited up to 20GB hard drive space allocated. The Boot2Docker package installer ships with a VMDK volume, which VirtualBox's native tools cannot resize.

We explain in following manual how to resize space.

Note: After that, when hard drive space will be too short and the drive is in VDI format, use this tutorial starting on GParted for resizing /sd1 to new size define in VirtualBox interface for hard drives.
