Kubernetes resource exporter

Prometheus exporter for Kubernetes resources

Why not using kube-state-metrics? Because they refused to generate custom metrics for group="" resources (Pods, Secrets, ...).

If you don't need custom metrics for group="" resources, try to use kube-state-metrics for custom resources.
