#### Extracting the APFS disk on Linux
In Docker-OSX, we are using `qcow2` images.
This means the image grows as you use it, but the guest OS thinks you have 200GB available.
**READ ONLY**
```bash
# mount the qemu image like a real disk
sudo modprobe nbd max_part=8
sudo qemu-nbd --connect=/dev/nbd0 ./image.img
sudo fdisk /dev/nbd0 -l
mkdir -p ./mnt
sudo mount /dev/nbd0p1 ./mnt
# inspect partitions (2 partitions)
sudo fdisk /dev/nbd0 -l
# mount using apfs-linux-rw OR apfs-fuse
mkdir -p ./part
sudo mount /dev/nbd0p2 ./part
sudo apfs-fuse -o allow_other /dev/nbd0p2 ./part
```
When you are finishing looking at your disk, you can unmount the partition, the disk, and remove the loopback device:
```bash
sudo umount ./part
sudo umount ./mnt
sudo qemu-nbd --disconnect /dev/nbd0
sudo rmmod nbd
```
