Building the KloudBuster VM and Docker images

This section describes how to rebuild:

  • the KloudButer VM Image from the git repository source code
  • the KloudBuster Docker image

A Linux server with python, git and qemu utilities installed is required.

Create a virtual environment (if not done already):

virtualenv vkb
source vkb/bin/activate

Ubuntu/Debian based:

sudo apt-get install python-dev git qemu-utils
pip install PyYAML

Redhat/Fedora/CentOS based:

sudo yum install python-devel git qemu-img
pip install PyYAML

Build the image with below commands:

# Clone the kloudbuster repository if you have not done so
git clone
cd kloudbuster
# Install kloudbuster
pip install -e .
# Run the build image script
$ ./

After a few minutes, the qcow2 and container images will be built and available in the same directory. The qcow2 and container images will be named after the version (e.g. kloudbuster-7.0.0.qcow2 and berrypatch/kloudbuster:7.0.0).

Pushing the Docker container to DockerHub

The KloudBuster Docker images are published in the DockerHub berrypatch repository:

To publish you need to be a member of the berrypatch kloudbuster team. After the login (requires your DockerHub username and password), push the appropriate version to berrypatch:

sudo docker login
sudo docker push berrypatch/kloudbuster:7.0.0
