About Kured

Kured provides a Kubernetes daemonset that performs safe automatic node reboots. It watches for a reboot sentinel file or the successful run of a sentinel command. It uses a lock in the API server to ensure only one node reboots at a time. It can defer reboots when active Prometheus alerts or selected pods are present. It cordons and drains worker nodes before reboot and uncordons them afterward. Kured is a Cloud Native Computing Foundation Sandbox project.

How to evaluate Containers & Kubernetes

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Kured. It comes from our Kubernetes Platforms buyer guide.

25%

Control Plane & Day-2 Lifecycle

Managed vs. self-managed control plane and its SLA; how Kubernetes version upgrades roll (in-place, surge, blue-green) and how disruptive they are to running pods; long-term-support version options; CVE patch cadence and how quickly fixes reach the fleet; automated node remediation and certificate rotation

20%

Fleet & Multi-Cluster Management

Single console and API to govern many clusters across clouds, on-prem, and edge; declarative cluster lifecycle and config (Cluster API or equivalent); fleet-wide policy and drift detection; zero-touch provisioning for edge; whether it manages clusters it did not create (imported/attached) or only its own

20%

Security & Compliance

Default-deny posture and admission control (Pod Security, OPA/Kyverno); image scanning and signing in the supply chain; RBAC plus OIDC/enterprise-identity integration; network policy and microsegmentation; CIS-benchmark conformance, audit logging, and FedRAMP/FIPS coverage where regulated

15%

Networking, Storage & Service Mesh

CNI options and how locked-in the default is; ingress and gateway controllers with TLS, rate-limiting, and WAF; CSI drivers for block/file/object and stateful-workload maturity; service mesh integration (Istio, Linkerd, Cilium); cross-cluster connectivity and load balancing

10%

Developer Experience & Self-Service

Namespace and cluster self-service vs. ticket-based provisioning; GitOps support (Argo CD, Flux) as a first-class workflow; developer portal and golden-path integration (Backstage or built-in console); IDE plugins and local-dev parity; how opinionated the platform is about how teams ship

10%

Cost, Portability & Commercial Model

Licensing unit (per-core, per-node, per-cluster, consumption) and how it scales with you; control-plane and extended-support fees; realistic exit cost and how provider-shaped the abstractions are; GPU/AI scheduling support; ecosystem breadth (operators, Helm, marketplace) and how much you must self-integrate
