BustaCluster a collection of wrapper scripts that build virtual HPC/Cloud clusters (e.g. a slurm cluster, kubernetes, ceph). The project is a way of experimenting with clusters, their configuration, and test scenarios and configurations in a non-production environment. All VMs are created using libvirt virtualisation, using tools like virt-builder and virsh.
Some aspects of the cluster builds are based on ansible playbooks, but clusters are mostly built via bash script command for testing various cluster configurations.
The clusters are not designed as production quality, and will often lack features that would be required in a production environment.

- libvirt
- guestfs-tool (virt-builder)
- ansible
Assuming a suitbale virt-builder image is available (see github.com/sglim2/virt-localrepo.git on how to build a local virt-builder repo)..
cd virt/k8s-basic
DISKSIZE=20G bash deploy.shThis will build a kubernetes cluster, resizing the root partition of each of the VMs to 20G, and all other parameters maintaining their default values (virt-builder image, k8s version, etc.)
