Helm chart를 사용하면, 키보드로 명령을 몇 줄 입력하면 모든 설치 및 구성이 끝난다.
내가 수행했던 명령을 캡쳐했다. 아래 예제를 따라하면 잘 설치된다.
/home/sejong/chart/prometheus# helm install -n almighty prometheus ./
NAME: prometheus
LAST DEPLOYED: Wed Oct 25 18:01:27 2023
NAMESPACE: almighty
STATUS: deployed

NOTES:
The Prometheus server can be accessed via port 80 on the following DNS name from within your cluster:
prometheus-server.almighty.svc.cluster.local
Get the Prometheus server URL by running these commands in the same shell:
export POD_NAME=$(kubectl get pods --namespace almighty -l "app.kubernetes.io/name=prometheus,app.kubernetes.io/instance=prometheus" -o jsonpath="{.items[0].metadata.name}")
kubectl --namespace almighty port-forward $POD_NAME 9090
The Prometheus alertmanager can be accessed via port 9093 on the following DNS name from within your cluster:
prometheus-alertmanager.almighty.svc.cluster.local
Get the Alertmanager URL by running these commands in the same shell:
export POD_NAME=$(kubectl get pods --namespace almighty -l "app.kubernetes.io/name=alertmanager,app.kubernetes.io/instance=prometheus" -o jsonpath="{.items[0].metadata.name}")
kubectl --namespace almighty port-forward $POD_NAME 9093

Helm chart가 잘 만들어져 있어서 큰 노력없이 클러스터 구축이 끝났다.
Helm chart를 만든 분께 감사하다는 말을 전하고 싶다.
