值文件中的舵连接列表

Question

我正在寻找一种解决方案，将我的 values.yaml 中的列表转换为逗号分隔的列表。

值.yaml

app:
  logfiletoexclude:
    - "/var/log/containers/kube*"
    - "/var/log/containers/tiller*"

_helpers.tpl：

{{- define "pathtoexclude" -}}
{{- join "," .Values.app.logfiletoexclude }}
{{- end -}}

配置图：

<source>
  @type tail
  path /var/log/containers/*.log
  exclude_path [{{ template "pathtoexclude" . }}]
  ...
  ...
</source>

问题是我的结果中缺少引号

 exclude_path [/var/log/containers/kube*,/var/log/containers/tiller*]

我该如何修复它才能拥有：

  exclude_path ["/var/log/containers/kube*","/var/log/containers/tiller*"] 

我试过：

{{- join "," .Values.app.logfiletoexclude | quote}}

但这给了我：

exclude_path ["/var/log/containers/kube*,/var/log/containers/tiller*"] 

谢谢

Answer 1

双引号应该在.Values.app.logfiletoexclude值中转义。

values.yaml 是：

app:
  logfiletoexclude:
    - '"/var/log/containers/kube*"'
    - '"/var/log/containers/tiller*"'

_helpers.tpl 是：

{{- define "pathtoexclude" -}}
{{- join "," .Values.app.logfiletoexclude }}
{{- end -}}

最后我们有：

exclude_path ["/var/log/containers/kube*","/var/log/containers/tiller*"]

Answer 2

我是这样解决的：

在values.yaml（引号无关紧要）：

elements:
- first element
- "second element"
- 'third element'

在_helpers.tpl：

{{- define "mychart.commaJoinedQuotedList" -}}
{{- $list := list }}
{{- range .Values.elements }}
{{- $list = append $list (printf "\"%s\"" .) }}
{{- end }}
{{- join ", " $list }}
{{- end }}

在templates/mytemplate.yaml：

elements: {{ include "mychart.commaJoinedQuotedList" . }}
