Elastic Cloud on Kubernetes (ECK) 설치

* AWS EKS(Amazon Elastic Kubernetes Service) 에 설치한 기록입니다.

 

- 기본 설정 적용

kubectl create -f https://download.elastic.co/downloads/eck/2.0.0/crds.yaml
kubectl apply -f https://download.elastic.co/downloads/eck/2.0.0/operator.yaml

- 먼저 PV(PersistentVolume)를 설정해 줍니다. 저렴하게 저장하기위해 st1을 위해 셋팅했습니다.

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: hdd
  annotations:
    storageclass.kubernetes.io/is-default-class: "false"
provisioner: kubernetes.io/aws-ebs
parameters:
  type: st1
  fsType: ext4
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-elastic
  namespace: default

spec:
  accessModes:
    - ReadWriteOnce
  awsElasticBlockStore:
    fsType: ext4
    volumeID: aws://ap-northeast-2c(리젼)/볼륨ID
  capacity:
    storage: 500Gi
  persistentVolumeReclaimPolicy: Delete
  storageClassName: hdd

- ElasticSearch를 생성합니다. 미리 생성한 PV에 자동으로 PVC(PersistentVolumeClaim)가 연결됩니다.

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: es
spec:
  version: 8.0.1
  nodeSets:
    - name: default
      count: 1      
      podTemplate:
        spec:
          containers:
            - name: elasticsearch
              env:
                - name: ES_JAVA_OPTS
                  value: -Xms1g -Xmx1g
              resources:
                requests:
                  memory: 2Gi
                  cpu: 2
                limits:
                  memory: 4Gi
      volumeClaimTemplates:
        - metadata:

          spec:
            accessModes:
              - ReadWriteOnce
            resources:
              requests:
                storage: 500Gi
            storageClassName: hdd

- Kibana를 셋팅합니다.

Ingress는 nginx-ingress기준으로 설정했습니다.

apiVersion: kibana.k8s.elastic.co/v1
kind: Kibana
metadata:
  name: es
spec:
  version: 8.0.1
  count: 1
  elasticsearchRef:
    name: es

          env:
            - name: NODE_OPTIONS

          resources:
            requests:
              memory: 0.5Gi
              cpu: 0.5
            limits:
              memory: 1Gi
              cpu: 1

- 리눅스

kubectl get secret es-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode; echo

- 파워쉘

$s=kubectl get secret es-es-elastic-user -o=jsonpath='{.data.elastic}'
[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($s))

 

https://kibana.hwani.net(설정 도메인) 으로 로 접속하여 

아이디 : elastic

암호 : 쉘내용

으로 접속합니다.

 

기본 설정이 끝났습니다.
