vbox-img Docker image

A Docker image that allows using vbox-img to convert virtual disk images.

No VirtualBox, VMWare, qemu-img, or vmdk-tool required.

With this image you can convert vmdk, vdi, vhd, and raw images from and to.

The goal of making this image was to enable the use case of converting a .ova file containing a monolithicSparse .vmdk file into an .ova file containing a streamOptimized .vmdk file.

Usage

Build

$ docker build -t vbox-img .

Convert monolithicSparse VMDK into streamOptimized VMDK

$ docker run --rm -i \
    -v $PWD/coreos_production_vmware_image.vmdk:/tmp/coreos_production_vmware_image.vmdk \
    vbox-img convert \
        --srcfilename /tmp/coreos_production_vmware_image.vmdk \
        --stdout \
        --dstformat VMDK \
        --variant Stream \
    > coreos_production_vmware_image_stream.vmdk
Converting image "/tmp/coreos_production_vmware_image.vmdk" with size 9116319744 bytes (8694MB)...

Default Usage

$ docker run --rm -it -v my_image.vmdk:/tmp/my_image.vmdk vbox-img
