在Helm configMap中包含文件内容后如何控制缩进?

我正在为我的Helm图表设置ConfigMap。

按照优良作法,我想通过单独的文件而不是内联的方式包含非Yaml资源。目前,我正在尝试在ConfigMap中的“数据”下同时包含一个xml文件和一个tpl帮助程序。在下面的代码中,两者均被正确读取。但是我似乎无法使键的缩进正常工作。

我的ConfigMap:

apiVersion: v1
kind: ConfigMap
metadata:
    name: {{ template "name" . }}
    labels:
        app: {{ template "name" . }}
        chart: {{ .Chart.Name }}-{{ .Chart.Version | replace "+" "_" }}
        release: {{ quote .Release.Name }}
        heritage: {{ quote .Release.Service }}
        name: {{ template "name" . }}
data:
    logback.xml: |-
        {{- .Files.Get "application-resources/logback.xml" | nindent 8 -}}
    application.yml: |-
        {{- include "application.yml" . | nindent 8 -}}

这会产生以下缩进(为了便于阅读,删除了实际值):

apiVersion: v1
kind: ConfigMap
metadata:
    name: erklaering-anden-lov-detektor-app
    labels:
        app: name-of-app
        chart: name-of-chart
        release: "release-name"
        heritage: "Tiller"
        name: name-of-app
data:
    logback.xml: |-
      <?xml version="1.0" encoding="UTF-8"?>
      <configuration scan="true">
          <xml-stuff>
      </configuration>
      application.yml: |-    
      application.yml.contents

应该是:

apiVersion: v1
kind: ConfigMap
metadata:
    name: erklaering-anden-lov-detektor-app
    labels:
        app: name-of-app
        chart: name-of-chart
        release: "release-name"
        heritage: "Tiller"
        name: name-of-app
data:
    logback.xml: |-
      <?xml version="1.0" encoding="UTF-8"?>
      <configuration scan="true">
          <xml-stuff>
      </configuration>
    application.yml: |-    
      application.yml.contents

我机智了。我究竟做错了什么?如何使yaml恢复识别ConfigMap自身的缩进和/或显式控制它?

答案 0 :(得分:0)

尝试一下:

data:
    logback.xml: |-
        {{- .Files.Get "application-resources/logback.xml" | nindent 8 }}
    application.yml: |-
        {{- include "application.yml" . | nindent 8 -}}

我从第三行中删除了“-”,因为它删除了以下空格。
