如何在头盔图表中从values.yaml到_helpers.tpl获取值 [英] How to get values from values.yaml to _helpers.tpl in helm charts

问题描述

这是values.yaml文件.它包含以下内容，当我尝试将其放入_helper.tpl时，我会立即获取Helm template failed. Error: render error in "windows/templates/ingresses/windows.yaml": template: windows/templates/_helpers.tpl:38:18: executing "windows.certificate" at <.Values.ingress.enab...>: can't evaluate field ingress in type interface {} : exit status 1

This is values.yaml file. It contains the following and when I am trying to get it into _helper.tpl im getting Helm template failed. Error: render error in "windows/templates/ingresses/windows.yaml": template: windows/templates/_helpers.tpl:38:18: executing "windows.certificate" at <.Values.ingress.enab...>: can't evaluate field ingress in type interface {} : exit status 1

values.yaml

ingress:
    enabled: true
    tls: true
    certificate: ''
    issuer:
        name: letsencrypt-staging
    hosts:
        windows:
            - name: ''
            path: /

_helpers.tpl

 {{/*
 Calculate certificate
 */}}
 {{- define "windows.certificate" }}
 {{- printf .Values.ingress.enabled }}  // error line is this. line no 38
 {{- end }}

在windows.yaml中

    - secretName: {{ template "windows.certificate" . }} // calling the helper method.

推荐答案

问题是缩进尝试

values.yaml

ingress:
  enabled: true
  tls: true
  certificate: ''
  issuer:
    name: letsencrypt-staging
  hosts:
    windows:
      - name: ''
        path: /

在辅助程序上也进行了一些更改，以控制定义块的输出

Also some changes on the helpers to control the output of the define block

_helpers.tpl

 {{/*
 Calculate certificate
 */}}
 {{- define "windows.certificate" }}
 {{- if .Values.ingress.enabled }}
 {{- printf .Values.ingress.certificate }} 
 {{- end }}     
 {{- end }}
