我如何在values.yaml中引用命名空间?

问题描述

我希望能够引用values.yaml中的当前名称空间，以使用它来添加诸如此类的某些值

I would like to be able to reference the current namespace in values.yaml to use it to suffix some values like this

# in values.yaml
someParam: someval-{{ .Release.Namespace }}

用这种方式定义它比进入我的所有模板并添加{{ .Release.Namespace }}更好.如果我可以在values.yaml中做到这一点，那就更清楚了，只需要在一个地方定义即可.

It much nicer to define it this way instead of going into all my templates and adding {{ .Release.Namespace }}. If I can do it in values.yaml it's much clearer and only needs to be defined in one place.

推荐答案

如果您知道someParam可能包含模板构造，Helm会包含 tpl 函数对其进行解释.

If you know that someParam might contain templating constructs, Helm includes a tpl function that interprets it.

- name: SOME_VARIABLE
  value: {{ .Values.someParam | tpl }}

如果图表允许这样做，通常会对其进行记录.作为一个具体示例， helm/charts PostgreSQL图表记录了其configurationConfigMap设置为

If a chart allows this it generally documents it. As a specific example, the helm/charts PostgreSQL chart documents that its configurationConfigMap setting is

因此，对于该特定值，您可以将模板宏放在values.yaml文件中.

So for that specific value, you can put a template macro in the values.yaml file.
