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, preemptible workers, and snippets customization
Ready for Ingress, Prometheus, Grafana, CSI, and other optional addons
