If everything is working as intended, you can now delete the old VMDK file or archive it for backup purposes.To install the upcoming Windows update, Windows requires 32 GB of free space, an increase from the (frankly, paltry) 16 GB needed for 32-bit versions and the 20 GB needed for the 64-bit versions. Run docker-machine start and it should boot your Docker machine with the resized virtual disk. Once you have done that, shutdown the GParted VM.Īttach the VDI file to your "default" machine. There are a lot of detailed instructions how to do this on the internet, for example here. It will boot GParted and you can then use it to resize the partition to use the entire disk. Attach your VDI disk and the GParted Live CD to the new machine. To resize the partition to fit the size of the disk, download GParted and create a new virtual machine. Now the disk is resized, but the partition is not. The last parameter of the following command specifies the new size in MB: VBoxManage modifyhd "C:\Users\me\.docker\machine\machines\default\disk.vdi" -resize 30720 Afterwards, clone the VMDK file to a VDI file: VBoxManage clonemedium disk -format VDI "C:\Users\me\.docker\machine\machines\default\disk.vmdk" "C:\Users\me\.docker\machine\machines\default\disk.vdi" Go to your VirtualBox interface and detach the VMDK file from your "default" machine. So, before you can resize it, you have to convert it to a VDI file.
Here is how you can resize your disk without losing any of your data.ĭocker Toolbox creates a VMDK file per default. I was not prepared to lose any of my existing images or containers, so neither creating a new disk nor pruning my data were options for me. You can use the modifymedium command to change disk size: vboxmanage modifymedium docker-vm.vdi -resize 100000 By default Docker Machine uses VirtualBox, which has the vboxmanage command line tool for working with VMs. You can resize without having to delete the VM and recreate it. $ docker-machine create -d virtualbox -virtualbox-disk-size "100000" default Open Docker Quickstart Terminal, remove the virtual docker-machine and add a new one: $ docker-machine rm default
