Create gentoo openstack-compatible images
gentoo-cloud-image-builder is meant to be run from a qemu compatible host. The high-level process includes booting a vm (using qemu) to the gentoo install cd/environment and subsequently automating a complete install.
In order to build an image you simply need to clone the repo and ensure you have a few standard deps on your host machine including:
On the host:
./launch.sh -t build
# give yourself a bigger console
vga=791On the vm after booting the gentoo installer:
# optionally launch screen or tmux
mkdir -p /mnt/builder
mount /dev/disk/by-label/builder /mnt/builder
/mnt/builder/full_install.shAt this point kick back and relax. Your image will be ready shortly. Once everything is done you can halt the vm and test it out by running:
# start the new image (any changes made to the live os will not persist in the image)
# login with gentoo:gentoo (note these creds are *NOT* baked into the image)
./launch.sh -t test
# on another terminal
tail -f log/console.logYou may shrink the image by using virt-sparsify
virt-sparsify --compress gentoo.img gentoo-$(date +%Y-%m-%d).img
Once you have a valid image you can upload to openstack:
glance image-create --name 'gentoo (20150507) x86_64' --disk-format qcow2 --container-format bare --is-public true --file gentoo.img --progress
