Kubernetes 舵图误差可以'；t计算类型接口{}中的字段值

我知道这是某种语法/yaml结构相关的错误，但消息太神秘了，我不知道问题是什么：

Error: render error in "mychart/templates/ingress.yaml": template: mychart/templates/ingress.yaml:35:37: executing "mychart/templates/ingress.yaml" at <.Values.network.appP...>: can't evaluate field Values in type interface {}

这是入口。yaml：

{{- $fullName := include "mychart.fullname" . -}}
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: {{ $fullName }}
  labels:
    app.kubernetes.io/name: {{ include "mychart.name" . }}
    helm.sh/chart: {{ include "mychart.chart" . }}
    app.kubernetes.io/instance: {{ .Release.Name }}
    app.kubernetes.io/managed-by: {{ .Release.Service }}
  {{- with .Values.ingress.annotations }}
  annotations:
    {{- toYaml . | nindent 4 }}
  {{- end }}
spec:
{{- if .Values.ingress.tls }}
  tls:
  {{- range .Values.ingress.tls }}
    - hosts:
      {{- range .hosts }}
        - {{ . | quote }}
      {{- end }}
      secretName: {{ .secretName }}
  {{- end }}
{{- end }}
  rules:
  {{- range .Values.ingress.hosts }}
    - host: {{ .host | quote }}
      http:
        paths:
        {{- range .paths }}
          - path: {{ . }}
            backend:
              serviceName: {{ $fullName }}
              servicePort: {{ .Values.network.appPort }}
        {{- end }}
  {{- end }}

为什么

{{.Values.network.appPort}

不起作用？我在其他地方使用过同样结构的值，这不只是范围问题吗

试试下面的东西

{{- $fullName := include "mychart.fullname" . -}}
{{- $networkAppPort  := .Values.network.appPort -}}
...
.... omitted code
...
      http:
        paths:
        {{- range .paths }}
          - path: {{ . }}
            backend:
              serviceName: {{ $fullName }}
              servicePort: {{ $networkAppPort }}
        {{- end }}
  {{- end }}

对于YAML，还需要具有任何可选值的直接父级

就像你在建造舵的过程中试图在一些yaml中检查“a.b.c”，它会给出类似的错误。要求a.b至少在default values.yaml中

通过在-

中查看详细信息来解决问题。我使用helm3，当我运行

helm template my chart

时，出现了相同的错误消息。就我而言，我在

values.yaml

中定义错误

错误配置（在我的

值中，
路径
下的yaml

缺少

路径

）：

像这样更正入口定义，它可以工作

ingress:
  enabled: true
  annotations:
     kubernetes.io/ingress.class: "nginx"
     nginx.ingress.kubernetes.io/rewrite-target: /$2
     nginx.ingress.kubernetes.io/ssl-redirect: "false"
     nginx.ingress.kubernetes.io/use-regex: "true"

  hosts:
    - host:
      paths:
      - path: "/dev(/|$)(.*)"
  tls: []

我的入口模板，

ingres.yaml

，通过helm自动生成

{{- if .Values.ingress.enabled -}}
{{- $fullName := include "bsb-lookup.fullname" . -}}
{{- $svcPort := .Values.service.port -}}
{{- if semverCompare ">=1.14-0" .Capabilities.KubeVersion.GitVersion -}}
apiVersion: networking.k8s.io/v1beta1
{{- else -}}
apiVersion: extensions/v1beta1
{{- end }}
kind: Ingress
metadata:
  name: {{ $fullName }}
  labels:
    {{- include "bsb-lookup.labels" . | nindent 4 }}
  {{- with .Values.ingress.annotations }}
  annotations:
    {{- toYaml . | nindent 4 }}
  {{- end }}
spec:
  {{- if .Values.ingress.tls }}
  tls:
    {{- range .Values.ingress.tls }}
    - hosts:
        {{- range .hosts }}
        - {{ . | quote }}
        {{- end }}
      secretName: {{ .secretName }}
    {{- end }}
  {{- end }}
  rules:
    {{- range .Values.ingress.hosts }}
    - host: {{ .host | quote }}
      http:
        paths:
          {{- range .paths }}
          - path: {{ .path }}
            backend:
              serviceName: {{ $fullName }}
              servicePort: {{ $svcPort }}
          {{- end }}
    {{- end }}
  {{- end }}

嗯，你能解释一下吗？我找不到好的文档来解释这个范围相关的东西。在另一个模板（service.yaml）中，我没有在yaml文件的顶部定义这样的变量，我可以直接在整个文件中执行

{{include“bombora atlantis.fullname.”}

，它只是工作而已-ingress.yaml与red888有什么不同。很难说为什么它在您的情况下有效，但我假设您只是将一个作用域（

）传递给include。舵机范围文件的当前位置
