How to convert VMDK to a Docker image

qemu-img convert -f vmdk -O raw MyImage-disk1.vmdk myimage.img

Next, After the raw has been created you can apply Guestfish:

$ guestfish -a myimage.img --ro
$ ><fs> run

$ ><fs> list-filesystems 
/dev/sda1: ext4
/dev/VolGroup/lv_root: ext4
/dev/VolGroup/lv_swap: swap
$ ><fs> mount /dev/VolGroup/lv_root /
$ ><fs> tar-out / - | xz --best >>  myimage.xz
$ ><fs> exit

Now, Importing myimage.xz into docker:

$ cat mytry.xz | docker import - mydockerimage

Next, Look inside the container:

$ docker run -it mydockerimage bash

It’s work!!!!!
