* Disable Kubelet Graceful Node Shutdown on worker nodes (enabled in Kubernetes v1.25.0 https://github.com/poseidon/typhoon/pull/1222) * Graceful node shutdown shutdown allows 30s for critical pods to shutdown and 15s for regular pods to shutdown before releasing the inhibitor lock to allow the host to shutdown * Unfortunately, both pods and the node are shutdown at the same time at the end of the 45s period without further configuration options. As a result, regular pods and the node are shutdown at the same time. In practice, enabling this feature leaves Error or Completed pods in kube-apiserver state until manually cleaned up. This feature is not ready for general use * Fix issue where Error/Completed pods are accumulating whenever any node restarts (or auto-updates), visible in kubectl get pods * This issue wasn't apparent in initial testing and seems to only affect non-critical pods (due to critical pods being killed earlier) But its very apparent on our real clusters Rel: https://github.com/kubernetes/kubernetes/issues/110755 |

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
- Advanced features like snippets customization
- Ready for Ingress, Prometheus, Grafana, and other optional addons
