在kubernetes中执行清单文件时获取标签验证错误

我正在尝试部署kubernetes清单文件，但由于下面的ValidationError而失败

错误：

error validating data: ValidationError(Deployment.spec.selector): unknown field "app" in io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelector; if you choose to ignore these errors, turn validation off with --validate=false

清单文件：

请验证我的清单文件是否正确，如果我遗漏了什么，请告诉我

您的部署中缺少标签选择器，模板下的标签也在部署中丢失，您的服务标签选择器应该与这些标签匹配

匹配标签：首先，只有在有标签时才需要使用选择器。您必须在部署元数据中定义标签，并在副本集中使用它

apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: elastickibana
      labels:
        app: elastickibana
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: elastickibana
      template:
        metadata:
          labels:
            app: elastickibana
        spec:
          containers:
          - name: elk
            image: daniccan/kibana-plugin-tester:latest
            imagePullPolicy: Always
            ports:
            - containerPort: 5601
            - containerPort: 9200
            env:
            - name: KIBANA_VERSION
              value: 6.8.2
            - name: PLUGIN_FILE_NAME
              value: kibana-c8-plugin-Alpha-0.0.1-Kibana-6.8.2.zip
            - name: KIBANA_PLUGIN_PATH
              value: /home/sreenivasa/Projects/c8/infrastructure/capsule8-sandbox
    ---
    kind: Service
    apiVersion: v1
    metadata:
      name: elk-service
      labels:
        app: elastickibana

      externalIPs:
      - 10.0.2.15

您的服务也不正确：它需要匹配pod的标签，如果不匹配，服务将不会分配给任何端点（pod IP）
