如何使用Helm获取子图表的名称? [英] How to get the name of a child chart with Helm?

问题描述

我有一个舵图，要求将stable/redis作为子图.父图表需要将redis服务公开为环境变量.

I have a helm chart that requires stable/redis as a child chart. The parent chart needs to expose the redis service as an environment variable.

redis图表包含一个名为redis.fullname的模板.如何在我的父图表中参考呢? IE.我希望在我的父级部署中使用类似的方法，但是它不起作用:

The redis chart includes a template called redis.fullname. How can I refer to this in my parent chart? I.e. I want something like this in my parent deployment but it doesn't work:

kind: Deployment
spec:
  template:
    containers:
        env:
        - name: REDIS_CLUSTER_SERVICE_HOST
          value: {{ template "redis.fullname" . }}

推荐答案

您可以在父图表中使用'{{ .Release.Name }}-redis'.我有同样的要求.这是我的示例，以备您查看-> https://github.com/kubernetes/charts/tree/master/incubator/distribution

You can use '{{ .Release.Name }}-redis' in your parent chart. I had same requirement. This is my example in case you want to take a look ->https://github.com/kubernetes/charts/tree/master/incubator/distribution
