在kubernetes中执行清单文件时出错

Question

[大家好，我正在研究kubernetes清单文件。当我尝试部署它时，显示一个称为验证数据的错误：（Deployment.sepc.selector）

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：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elastickibana
spec:
  replicas: 1
  selector:
    app: elastickibana
  template:
    metadata:
    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: elk-kibana
spec:
  type: LoadBalancer
  externalIPs:
  - 10.0.2.15
  selector:
    name: elk-kibana
  ports:
  - port: 5601
    name: elasticservice
  ports:
  - port: 9200
    name: serving-http

有人可以帮我解决错误。

您在部署中，在模板下，在部署中也缺少标签选择器，并且服务标签选择器应与这些标签匹配。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elastickibana
spec:
  replicas: 1
  selector:
    matchlabels:                     <--missing this
      app: elastickibana
  template:
    metadata:
      labels:                        <--and this
        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: elk-kibana
spec:
  type: LoadBalancer
  externalIPs:
  - 10.0.2.15
  selector:
    app: elastickibana             <--and this should be like this
  ports:
  - port: 5601
    name: elasticservice
  ports:
  - port: 9200
    name: serving-http

现在，在发布任何问题之前，请尝试进行调查。您可以通过仅匹配文档中的Deployment和Service示例来了解这些基础知识。
