kubernetes-helm - 值文件中的 Helm 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

双引号应该在 .Values.app.logfiletoexclude 中转义值。
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*"]
