This project is inspired by kube-state-metrics and kubectl.

This project is exposted kubernetes node resource metrics to prometheus. Following Metrics will be exposed.

kube_node_metrics_cpu_request
kube_node_metrics_cpu_limit
kube_node_metrics_mem_request_bytes
kube_node_metrics_mem_limit_bytes

These samples values should be equal to the result of kubectl describe node <node>.

Getting started

Available docker images can be fount in docker hub.

Try in Minikube

Please ensure you have minikube installed.

Run with following commands in your terminal:

minikube start
kubectl apply -f deploy.yaml

Run in Kubernetes

kubectl apply -f deploy.yaml

Build

build binary manually

go build .

build docker image

docker build . -t <image>:<tag>

Operating

This exporter also exposed a metric kube_node_metrics_last_full_sync_ok_time_seconds which indicates the last full sync timestamp in seconds. You can create alert rule to monitor the exporter health with the expression time() - kube_node_metrics_last_full_sync_ok_time_seconds > 300 and you will receive alert if the exporter is not sync sucessfully for 300 seconds.

TODO

1. support exposed node labels match given pattern
