skywalking使用ES做存储在K8S上的部署，使用实践_skywalking sw_storage_es_cluster_nodes

在Kubernetes环境中部署SkyWalking并使用Elasticsearch作为存储后端的步骤如下：

1. 创建Elasticsearch服务。
2. 创建SkyWalking OAP服务。
3. 创建SkyWalking UI服务。

以下是一个简化版的YAML配置文件示例，用于在Kubernetes中部署SkyWalking，并配置Elasticsearch作为存储后端。

# Elasticsearch Deployment
apiVersion: apps/v1
kind: Deployment
metadata:
  name: elasticsearch
spec:
  replicas: 1
  selector:
    matchLabels:
      app: elasticsearch
  template:
    metadata:
      labels:
        app: elasticsearch
    spec:
      containers:
      - name: elasticsearch
        image: docker.elastic.co/elasticsearch/elasticsearch-oss:7.10.0
        ports:
        - containerPort: 9200
        - containerPort: 9300
        env:
        - name: discovery.type
          value: single-node
 
# SkyWalking OAP Service
apiVersion: v1
kind: Service
metadata:
  name: skywalking-oap-service
spec:
  selector:
    app: skywalking-oap
  ports:
  - protocol: TCP
    port: 11800
    targetPort: 11800
 
# SkyWalking UI Service
apiVersion: v1
kind: Service
metadata:
  name: skywalking-ui-service
spec:
  type: NodePort
  selector:
    app: skywalking-ui
  ports:
  - protocol: TCP
    port: 80
    targetPort: 80
    nodePort: 30001
 
# SkyWalking OAP Deployment
apiVersion: apps/v1
kind: Deployment
metadata:
  name: skywalking-oap
spec:
  replicas: 1
  selector:
    matchLabels:
      app: skywalking-oap
  template:
    metadata:
      labels:
        app: skywalking-oap
    spec:
      containers:
      - name: skywalking-oap
        image: apache/skywalking-oap-server:8.9.0
        ports:
        - containerPort: 11800
        env:
        - name: SW_STORAGE
          value: elasticsearch
        - name: SW_STORAGE_ES_CLUSTER_NODES
          value: elasticsearch:9200
 
# SkyWalking UI Deployment
apiVersion: apps/v1
kind: Deployment
metadata:
  name: skywalking-ui
spec:
  replicas: 1
  selector:
    matchLabels:
      app: skywalking-ui
  template:
    metadata:
      labels:
        app: skywalking-ui
    spec:
      containers:
      - name: skywalking-ui
        image: apache/skywalking-ui:8.9.0
        ports:
        - containerPort: 80
        env:
        - name: SW_OAP_ADDRESS
          value: skywalking-oap-service:11800

在这个配置中，Elasticsearch作为后端存储被用于SkyWalking。请确保Elasticsearch服务可被SkyWalking OAP服务访问，并且在SW_STORAGE_ES_CLUSTER_NODES环境变量中正确配置了Elasticsearch节点地址。

部署这些资源到Kubernetes集群中，并通过对应的服务访问
