使用eck-operator 快速部署 es 开发环境

前提

• 需要一个 kubernetes 集群
• 需要提供 csi（数据持久化）

部署步骤

1. 部署 crd

kubectl create -f https://download.elastic.co/downloads/eck/2.12.1/crds.yaml

2. 部署elastic-operator

# 默认在 elastic-system命名空间下
kubectl apply -f https://download.elastic.co/downloads/eck/2.12.1/operator.yaml

3. 查看部署日志

kubectl -n elastic-system logs -f statefulset.apps/elastic-operator

4. 部署一个 elasticsearch 集群实例

cat <<EOF | kubectl apply -f -
apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: elastic01
spec:
  version: 8.13.1
  volumeClaimDeletePolicy: DeleteOnScaledownOnly
  http:
    tls:
      selfSignedCertificate:
        disabled: true
  nodeSets:
  - name: default
    count: 1
    volumeClaimTemplates:
    - metadata:
        name: elasticsearch-data
      spec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: 5Gi
        storageClassName: nfs-storage-class
    config:
      node.store.allow_mmap: false
EOF

5. 查看集群状态

# 查看 es 资源
k get es
NAME        HEALTH   NODES   VERSION   PHASE   AGE
elastic01   green    1       8.13.1    Ready   38m
# 查看 pod 资源
k get po |grep elastic01
elastic01-es-default-0                             1/1     Running   0          38m
# 查看 svc 资源
k get svc |grep elastic01
elastic01-es-default         ClusterIP   None             <none>        9200/TCP                     39m
elastic01-es-http            NodePort    10.98.160.4      <none>        9200:31977/TCP               39m
elastic01-es-internal-http   ClusterIP   10.100.120.30    <none>        9200/TCP                     39m
elastic01-es-transport       ClusterIP   None             <none>        9300/TCP                     39m

6. 查看认证信息

kubectl get secret elastic01-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode; echo

7. 本地连接测试
   curl -u "elastic:xxxxxxxxx" -k "http://10.98.160.4:9200"

{
  "name" : "elastic01-es-default-0",
  "cluster_name" : "elastic01",
  "cluster_uuid" : "_T5mzPPwRMqGSjnTYnMVWA",
  "version" : {
    "number" : "8.13.1",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "9287f29bba5e270bd51d557b8daccb7d118ba247",
    "build_date" : "2024-03-29T10:05:29.787251984Z",
    "build_snapshot" : false,
    "lucene_version" : "9.10.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

8. 部署 kibana

cat <<EOF | kubectl apply -f -
apiVersion: kibana.k8s.elastic.co/v1
kind: Kibana
metadata:
  name: kibana01
spec:
  version: 8.13.1
  count: 1
  elasticsearchRef:
    name: elastic01
  http:
    tls:
      selfSignedCertificate:
        disabled: true
    service:
      spec:
        type: NodePort
        ports:
        - port: 5601
          targetPort: 5601
EOF
