Typhoon 
Typhoon is a minimal and free Kubernetes distribution.
- Minimal, stable base Kubernetes distribution
- Declarative infrastructure and configuration
- Free (freedom and cost) and privacy-respecting
- Practical for labs, datacenters, and clouds
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
Features 
- Kubernetes v1.25.0 (upstream)
- Single or multi-master, Calico or Cilium or flannel networking
- On-cluster etcd with TLS, RBAC-enabled, network policy, SELinux enforcing
- Advanced features like worker pools, spot workers, and snippets customization
- Ready for Ingress, Prometheus, Grafana, CSI, and other optional addons
