k8s部署elasticseadrch的yml文件

以下是一个部署 Elasticsearch 到 Kubernetes 集群的 YAML 文件示例：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: elasticsearch
spec:
  serviceName: elasticsearch
  replicas: 3
  selector:
    matchLabels:
      app: elasticsearch
  template:
    metadata:
      labels:
        app: elasticsearch
    spec:
      containers:
      - name: elasticsearch
        image: docker.elastic.co/elasticsearch/elasticsearch:7.6.2
        env:
        - name: cluster.name
          value: my-cluster
        - name: discovery.seed_hosts
          value: "elasticsearch-0.elasticsearch,elasticsearch-1.elasticsearch,elasticsearch-2.elasticsearch"
        - name: cluster.initial_master_nodes
          value: "elasticsearch-0,elasticsearch-1,elasticsearch-2"
        ports:
        - containerPort: 9200
          name: rest
        - containerPort: 9300
          name: inter-node
        volumeMounts:
        - name: data
          mountPath: /usr/share/elasticsearch/data
      volumes:
      - name: data
        persistentVolumeClaim:
          claimName: elasticsearch-data
---
apiVersion: v1
kind: Service
metadata:
  name: elasticsearch
spec:
  ports:
  - port: 9200
    name: rest
  - port: 9300
    name: inter-node
  clusterIP: None
  selector:
    app: elasticsearch

这个示例假设您已经创建了一个永久卷申明 (PVC) 名为 `elasticsearch-data`，用于 Elasticsearch 数据存储。在上面的 YAML 文件中，Elasticsearch 容器被定义为一个有状态集合 (StatefulSet)，其中有 3 个副本。此外，还定义了一个名为 `elasticsearch` 的服务，用于将流量路由到 Elasticsearch 容器。
