설치 전 환경 설정

PersistentVolumeClaim 생성

  • pvc.yaml 파일 생성 (storageClass는 prometheus 설치시 생성한 sc 사용)

    $ vi pvc.yaml apiVersion: v1 kind: PersistentVolumeClaim metadata: name: elastic-stack-elasticsearch-master-elastic-stack-elasticsearch-master-0 namespace: "gitlab-managed-apps" spec: storageClassName: "managed-nfs-storage" accessModes: - ReadWriteOnce resources: requests: storage: 10Gi --- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: elastic-stack-elasticsearch-master-elastic-stack-elasticsearch-master-1 namespace: "gitlab-managed-apps" spec: storageClassName: "managed-nfs-storage" accessModes: - ReadWriteOnce resources: requests: storage: 10Gi --- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: elastic-stack-elasticsearch-master-elastic-stack-elasticsearch-master-2 namespace: "gitlab-managed-apps" spec: storageClassName: "managed-nfs-storage" accessModes: - ReadWriteOnce resources: requests: storage: 10Gi

  • yaml 배포
    $ kubectl create -f pvc.yaml

  • persistentVolume 및 persistentVolumeClaim 생성 확인
