Grafana dashboard with kindnet metrics
In this tutorial, we will guide you through the process of setting up a Grafana dashboard to visualize metrics collected by kindnet, a CNI (Container Network Interface) plugin for Kubernetes. By the end of this tutorial, you will have a fully functional monitoring setup that includes Prometheus for metric collection and Grafana for visualization.
Prerequisites
Before you begin, ensure you have the following tools installed on your local machine:
- Docker Desktop: Required to run Kubernetes clusters locally.
- kind: A tool for running local Kubernetes clusters using Docker container nodes. You can install it by following the instructions on the kind website.
Steps
1. Create kind cluster without CNI
kind create cluster --config multi-node-k8s-no-cni.yaml --name home-lab
kubectl apply -f kindnet-custom-resources.yaml
3. Set Up namespace for monitoring and config map with Grafana dashboard, which uses kindnet metrics
kubectl apply -f monitoring-namespace.yaml
kubectl create configmap kindnet-dashboards --from-file=kindnet-dashboard.json -n monitoring
kubectl label configmap kindnet-dashboards grafana_dashboard=1 -n monitoring
4. Install and configure Grafana and Prometheus
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
helm install monitoring prometheus-community/kube-prometheus-stack --namespace monitoring --values grafana-prometheus-kindnet-scrape-config.yaml
5. Retrieve Grafana admin password
kubectl get secrets --namespace monitoring monitoring-grafana -o jsonpath="{.data.admin-password}" | base64 -d ; echo
6. Forward port for Grafana
kubectl port-forward --namespace monitoring svc/monitoring-grafana 3000:80
7. Access Grafana dashboard
Open your browser and go to http://localhost:3000. Log in with the admin credentials retrieved in the previous step.
Navigate to the Dashboards section:
Select the kindnet dashboard to view the metrics:
