kubernetes - 升级 helm 模板后无效的规范选择器

Question

我已经升级了掌 Helm 模板(手动)

以前的片段depoloyment.yaml :

apiVersion: apps/v1beta2 kind: Deployment metadata:   name: {{ template "measurement-collector.fullname" . }}   labels:
    app: {{ template "measurement-collector.name" . }}
    chart: {{ template "measurement-collector.chart" . }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }} spec:   replicas: {{ .Values.replicaCount }}   selector:
    matchLabels:
      app: {{ template "measurement-collector.name" . }}
      release: {{ .Release.Name }}

新的一个:

apiVersion: apps/v1beta2
kind: Deployment
metadata:
  name: {{ include "measurement-collector.fullname" . }}
  labels:
    app.kubernetes.io/name: {{ include "measurement-collector.name" . }}
    helm.sh/chart: {{ include "measurement-collector.chart" . }}
    app.kubernetes.io/instance: {{ .Release.Name }}
    app.kubernetes.io/managed-by: {{ .Release.Service }}
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app.kubernetes.io/name: {{ include "measurement-collector.name" . }}
      app.kubernetes.io/instance: {{ .Release.Name }}

新品 service.yaml :

  name: {{ include "measurement-collector.fullname" . }}
  labels:
    app.kubernetes.io/name: {{ include "measurement-collector.name" . }}
    helm.sh/chart: {{ include "measurement-collector.chart" . }}
    app.kubernetes.io/instance: {{ .Release.Name }}
    app.kubernetes.io/managed-by: {{ .Release.Service }}
spec:
  type: {{ .Values.service.type }}
  ports:
      protocol: TCP
      name: http
  selector:
    app.kubernetes.io/name: {{ include "measurement-collector.name" . }}
    app.kubernetes.io/instance: {{ .Release.Name }}

然后运行后: helm upgrade -i measurement-collector chart/measurement-collector --namespace prod --wait
我得到:

Error: UPGRADE FAILED: Deployment.apps "measurement-collector" is invalid: spec.selector: Invalid value: 
v1.LabelSelector{MatchLabels:map[string]string{"app.kubernetes.io/name":"measurement-collector", "app.kubernetes.io/instance":"measurement-collector"},         
MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable

如果更改选择器标签，则需要在部署之前先清除版本。
