迁移到Kubernetes 1.16所需的更改

Question

我有一个多组分平台，我为它创建了所需的舵机图表，它在Kubernetes <= 1.15上正常工作。

现在，我需要准备它们与k8s 1.16兼容。我认为只需将extensions/v1beta1更改为apps/v1就足够了，但在尝试在k8s上安装舵机图表后，我得到了以下错误：

Error: release test166 failed: Deployment.apps "bridge-http" is invalid: [spec.selector: Required value, spec.template.metadata.labels: Invalid value: map[string]string{"io.kompose.service":"bridge-http"}: `selector` does not match template `labels`]

这是我的yaml/helm文件，它在旧的k8s上工作：

---
apiVersion: v1
kind: Service
metadata:
  annotations:
    Process: bridge-http
  creationTimestamp: null
  labels:
    io.kompose.service: bridge-http
  name: bridge-http
spec:
  ports:
  - name: "9995"
    port: 9995
    targetPort: 9995
  selector:
    io.kompose.service: bridge-http
status:
  loadBalancer: {}

        - name: WWS_BRIDGE_HTTP_BROKER_DATA_USER
          value: {{ .Values.WWS_BRIDGE_HTTP_BROKER_DATA_USER | quote }}
        image: {{ .Values.image }}
        name: bridge-http
        readinessProbe:
          tcpSocket:
            port: 9995
          initialDelaySeconds: 5
          periodSeconds: 15
        ports:
        - containerPort: 9995
        resources:
          requests:
            cpu: 0.1
            memory: 250Mi
          limits:
            cpu: 2
            memory: 5Gi
      restartPolicy: Always
      imagePullSecrets:
      - name: wwssecret
status: {}

我在这里找不到关于选择器和标签的任何变化：https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/

那么，为什么我要得到这个错误，以及我如何解决它呢？

作为1.16升级的一部分，我们将扩展/v1beta1改为app/v1。除此之外，您还需要在主规范下添加下面的代码段。

kind: Deployment
metadata:
  annotations:
    Process: bridge-http
  creationTimestamp: null
  labels:
    io.kompose.service: bridge-http
  name: bridge-http
spec:
  replicas: 1
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        io.kompose.service: bridge-http  
  selector:
    matchLabels:
      app: bridge-http
