kube-node-status

kube-node-status is a containerized Golang application which continuously reports the status of Kubernetes nodes.

This becomes useful if you use a managed version of kube-state-metrics which does not support retrieving Kubernetes node metrics and you are not able to use a self-managed version of it.

This project is under active development. Use with caution.

helm repo add kube-node-status https://torbendury.github.io/kube-node-status
helm repo update
helm install kube-node-status kube-node-status/kube-node-status --create-namespace --namespace kube-node-status
