Re: [atomic-devel] creating qcow2 for proof of concept appliance

[Muayyad AlSadi <alsadi gmail com>]

without ostree it's 98 MB, 

OK: 98 MiB in 26 packages

there is no need to add grub, because I'm using fedora's grub (because their's did not work)

I've made an alpine qcow2 that booted (a bunch of losetup, chroots, fedora's grub2-install of fedora, ...)

assuming I ended with a qcow2 with a working alpine qcow2 + ostree + fedora's grub2

how to make that into ostree ?

it seems that their initrd is just a simple script, and it seems that supporting LVM in alpine is not fun

so I'll stop here

I've done the following so far

since I'm considering very minimal installation suitable for appliance, I considered fedora's busybox, but in that case I would need to create a statically linked ostree

as I mentioned I'm not doing this to be for production server nor a workstation

I tried to start with alpine linux, but they don't provide qcow2 images,

so I run 

mkdir alpine-root

docker run --rm -ti --name a1 -v `pwd`/alpine-root:/data/ alpine /bin/sh

and inside the container I run

apk --arch x86_64 -X http://nl.alpinelinux.org/alpine/edge/main/  -X http://nl.alpinelinux.org/alpine/edge/testing/ -U --allow-untrusted --root /data --initdb add alpine-base ostree linux-virtgrsec

the end result was

OK: 120 MiB in 67 packages

compared to 6 MB without ostree and kernel

I guess linux-virtgrsec is the smallest kernel they have

I'm not sure if 120MB for an embedded appliance is good or bad.

and this image does not have a bootloader yet

but ostree seems to be working!

now I have a directory /alpine-root having a working ostree and a kernel

what's next? add a bootloader and make that a qcow2 and make an ostree out of it

I would suggest directly to look at the repository [0] now.
It does the setup like it does in the magazine article.
In additional you can compose OSTree with customized packages for the Atomic host.
