This repository is intended to allow for the easy creation and customization of cloud images for use on KVM based cloud computing infrastructures. We are using Packer to create repeatable images.
The steps provided here were tested on CentOS 6.
-
Download Packer:
wget https://dl.bintray.com/mitchellh/packer/0.6.1_linux_amd64.zip -O packer.zip -
Unzip Packer
unzip packer.zip -d /usr/local/bin -
Install virt-sysprep
yum install -y libguestfs-tools-c -
Download this repository
wget https://github.com/viglesiasce/cloud-images/archive/master.zip -O cloud-images-master.zip -
Unzip this repository
unzip cloud-images-master.zip -
Enter the directory of the image you'd like to create
cd cloud-images-master/centos-6 -
Run Packer
packer build centos-packer.json -
Sysprep the image
virt-sysprep -a output-qemu/*.raw
Once that process completes you will have a RAW image in the output-qemu directory which is ready to be uploaded to your cloud of choice.
For example in Eucalyptus 4.0:
euca-install-image -i output-qemu/centos-6-base.raw --virtualization-type hvm -b centos-base -r x86_64 --name centos-base
In order to customize your image change the parameters in the json file found in each distro's folder. Here you can change the size, output format, or provisioning/customization steps.
For more information on how to customize a Packer run please see: http://www.packer.io/docs
In order to contribute a new distro send a pull request with a new folder with the name of the distribution. This folder should contain all the artifacts necessary to create the most basic functioning cloud image based on this distribution.
