In other words, can we create a disk image having exactly the same Linux userland a running container has and then boot from it? For this we would start with dumping container's root file system, luckily it's as simple as just running docker export , however, to finally accomplish the task a bunch of additional steps is needed... It basically means that running containers reuse the host's kernel while their userlands are completely separated and come from the appointed Linux distributions: Hence, we also need to address this discrepancy to bring container's state as close as possible to the full-fledged Debian installation. We just created a bootable Linux disk image which can be dumped to a real or virtual drive.7 days ago by sechilds
