I was able to extract the qcow2 from https://jenkins.linuxcontainers.org/view/Images/job/image-alpine/lastBuild/architecture=amd64,release=3.18,variant=default/ - I put it into disk.tar.gz and created a Dockerfile:

FROM scratch
ADD disk.tar.gz /

I can then run that image with /sbin/init like bootloose does. The start-up sequence ends with a loop trying to find a tty from /dev/tty1.../dev/tty4 for starting a console, but looks like it's "up" enough so that I can docker exec into it. Looks like everything is working, but there's no sshd preinstalled, other than that, it should probably work just fine as a "bootoose image". All bootloose does is that it starts a container with the command /sbin/init then docker execs into it and appends the ssh pubkey into /root/.ssh/authorized_keys.

There are go packages for interacting with the image server and reading qcow2 files, so I guess it would be possible to have bootloose download lxd images and create docker containers, but there would still have to be some customization for example to install sshd.

investigate how to use LXD images #54
