Grafana는 모니터링을 시각화하기 위한 도구입니다. helm을 이용하여 설치하므로, helm이 설치되어 있다는 것을 전제로 합니다.
1. 설치 방법
1. helm으로 grafana 설치
helm install --name air-grafana --namespace monitoring -f values.yaml stable/grafana
이때 사용한 values.yaml에서 가장 중요한 것은 외부 포트 오픈을 위해, service: NodePort를 지정해주었다는 것입니다. 또한 adminUser와 adminPassword를 지정해주어야 합니다.

NOTES:
1. Get your 'admin' user password by running:
kubectl get secret --namespace monitoring air-grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
2. The Grafana server can be accessed via port 80 on the following DNS name from within your cluster:
air-grafana.monitoring.svc.cluster.local
Get the Grafana URL to visit by running these commands in the same shell:
export NODE_PORT=$(kubectl get --namespace monitoring -o jsonpath="{.spec.ports[0].nodePort}" services air-grafana)
export NODE_IP=$(kubectl get nodes --namespace monitoring -o jsonpath="{.items[0].status.addresses[0].address}")
echo http://$NODE_IP:$NODE_PORT
3. Login with the password from step 1 and the username: admin
