1) EBS CSI Driver 먼저 설치


1
먼저 클러스터 이름과 계정 정보를 변수로 잡습니다.


export CLUSTER_NAME=my-eks-cluster
export REGION=ap-northeast-2
export ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)


2
EKS용 OIDC가 없다면 먼저 연결합니다


aws eks list-clusters --region ap-northeast-2
eks-demo

export REGION=ap-northeast-2
export CLUSTER_NAME=eks-demo
export ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
echo $CLUSTER_NAME
echo $REGION



eksctl utils associate-iam-oidc-provider \
  --cluster $CLUSTER_NAME \
  --region $REGION \
  --approve


3
# AWS 권장 방식대로 EBS CSI Driver용 IAM ServiceAccount를 만듭니다. (1분)


eksctl create iamserviceaccount \
  --name ebs-csi-controller-sa \
  --namespace kube-system \
  --cluster $CLUSTER_NAME \
  --region $REGION \
  --role-name AmazonEKS_EBS_CSI_DriverRole \
  --role-only \
  --attach-policy-arn arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy \
  --approve



4

그 다음 EKS add-on으로 드라이버를 설치합니다. EKS add-on 이름은 aws-ebs-csi-driver 입니다.


aws eks create-addon \
  --cluster-name $CLUSTER_NAME \
  --region $REGION \
  --addon-name aws-ebs-csi-driver \
  --service-account-role-arn arn:aws:iam::$ACCOUNT_ID:role/AmazonEKS_EBS_CSI_DriverRole




5
# 정상 상태 확인

aws eks describe-addon \
  --cluster-name $CLUSTER_NAME \
  --region $REGION \
  --addon-name aws-ebs-csi-driver \
  --query 'addon.status'

kubectl get pods -n kube-system | grep ebs

아래 두 종류가 보여야 합니다.

ebs-csi-controller
ebs-csi-node


(i-0dff2e951a0d0500a@eks-demo:kubecost) [root@kops-ec2 ~]# kubectl get pods -n kube-system | grep ebs
ebs-csi-controller-844bfd456c-7d4bn   6/6     Running   0          20s
ebs-csi-controller-844bfd456c-nvbtr   6/6     Running   0          20s
ebs-csi-node-k6pjc                    3/3     Running   0          20s





----------------------

kubecost 설치


# 2. Helm 레포지토리 추가 및 업데이트


# 1) Helm repo 등록
helm repo add kubecost https://kubecost.github.io/cost-analyzer/

# 2) repo 업데이트
helm repo update

# 3) namespace 생성
kubectl create namespace kubecost

# 4) Kubecost 설치 (중요: gp2 사용)
helm install kubecost kubecost/cost-analyzer \
  --namespace kubecost \
  --version 2.8.6 \
  --set kubecostToken="free" \
  --set global.clusterId="my-eks-cluster" \
  --set persistentVolume.storageClass=gp2 \
  --set prometheus.server.persistentVolume.storageClass=gp2





3
k ns kubecost


helm repo list
helm search repo kubecost/cost-analyzer --versions | head



4
kubectl get pvc -n kubecost
kubectl get pods -n kubecost



5
clear

# 오류 확인시
kubectl describe pods -n kubecost
kubectl get pvc -n kubecost
kubectl get storageclass



6
# 오류 확인시
clear
kubectl get pods -n kubecost -o wide
kubectl describe pvc kubecost-cost-analyzer -n kubecost
kubectl describe pvc kubecost-prometheus-server -n kubecost
kubectl get events -n kubecost --sort-by=.metadata.creationTimestamp

# 터미널 3

kubectl port-forward  --address 0.0.0.0 -n kubecost svc/kubecost-cost-analyzer 9090
