Kubernetes 头盔范围获得循环外的值

我在看他们的头盔范围的例子

yaml

favorite:
  drink: coffee
  food: pizza
pizzaToppings:
  - mushrooms
  - cheese
  - peppers
  - onions

掌舵

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ .Release.Name }}-configmap
data:
  myvalue: "Hello World"
  {{- with .Values.favorite }}
  drink: {{ .drink | default "tea" | quote }}
  food: {{ .food | upper | quote }}
  {{- end }}
  toppings: |-
    {{- range .Values.pizzaToppings }}
    - {{ . | title | quote }}
    - {{ .Values.favorite.drink }}
    {{- end }}

我更新了它，使它有一行

-{{.Values.favorite.drink}

但是当我运行

helmtemplate

时，我得到了错误

can't evaluate field Values

是否仍然可以从

范围

函数中访问顶级

值

并退出循环？

您可以使用一个变量：

  toppings: |-
    {{- $drink := .Values.favorite.drink }}
    {{- range .Values.pizzaToppings }}
    - {{ . | title | quote }}
    - {{ $drink }}
    {{- end }}

如果愿意，也可以将

值

分配给变量

  toppings: |-
    {{- $val := .Values }}
    {{- range .Values.pizzaToppings }}
    - {{ . | title | quote }}
    - {{ $val.favorite.drink }}
    {{- end }}

---

还可以使用指向根上下文的全局变量

$

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ .Release.Name }}-configmap
data:
  myvalue: "Hello World"
  {{- with .Values.favorite }}
  drink: {{ .drink | default "tea" | quote }}
  food: {{ .food | upper | quote }}
  {{- end }}
  toppings: |-
    {{- range $.Values.pizzaToppings }}
    - {{ . | title | quote }}
    - {{ $.Values.favorite.drink }}
    {{- end }}
