Cloud Images

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.

How To

1. Download Packer:

    wget https://dl.bintray.com/mitchellh/packer/0.6.1_linux_amd64.zip -O packer.zip
   

2. Unzip Packer

    unzip packer.zip -d /usr/local/bin
   

3. Install virt-sysprep

    yum install -y libguestfs-tools-c
   

4. Download this repository

    wget https://github.com/viglesiasce/cloud-images/archive/master.zip -O cloud-images-master.zip
   

5. Unzip this repository

    unzip cloud-images-master.zip
   

6. Enter the directory of the image you'd like to create

    cd cloud-images-master/centos-6
   

7. Run Packer

    packer build centos-packer.json
   

8. 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

Customizing your image

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

Contributing

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.
