This directory contains the scripts used to generate the Chameleon KVM and bare-metal CentOS 7 images. It relies on diskimage-builder.
There are a couple variants of images it can produce, assembled using the needed elements:
gpu- Includes CUDA framework
fpga- Includes Altera Nallatech tools
Images are created with diskimage-builder
sudo install-reqs.sh # install tools and dependencies python create-image.py base # create the "base" iamge with most recent cloud image
yum install qemu-img, may also require epel-release
apt-get install qemu-disk
pip install diskimage-builder
The main script takes the variant and revision number.
python create-image.py --help.
The output is dumped to a temporary folder.
At the end of its execution, the script provides the Glance command that can be used to upload the image to an existing OpenStack infrastructure.
The other scripts in the
elements directory are invoked by create-image.sh.
This script does the following:
- Download a CentOS 7 cloud image from upstream
- Customize it for Chameleon (see
elementsdirectory for details)
- Generate an image compatible with OpenStack KVM and bare-metal
The image must then be uploaded and registered with Glance (currently done manually, by running the Glance command given at the end of execution).
