UPD: Two years after creating this project I clearly can see some interest in building VM images from containers and/or Dockerfiles. If you’re aware of the real use of the docker-to-linux project, please drop me a message and share your experience. It may help me to develop a second generation of this tool covering real-world scenarios with a more user-friendly UX. Thanks!
There is no real goal behind this project. Just out of my curiosity what if:
- launch a base Linux container (debian, alpine, etc)
- pull in Linux kernel & init system (systemd, OpenRC, etc)
- dump container's filesystem to a disk image
- install bootloader (syslinux) to this image...
Then it should be probably possible to launch a real virtual machine with such an image!
Try it out:
make debian
qemu-system-x86_64 -drive file=linux.img,index=0,media=disk,format=raw
make clean
make alpine
qemu-system-x86_64 -drive file=linux.img,index=0,media=disk,format=raw
make clean
It works!
