在舵图中重用uuid

Question

使用uuid函数生成UUID。但需要帮助如何将该值发送到两个组件。

这是我的图表文件夹结构--

• 项目目录
  • 图表1
    • 模板
      • StateFulSet.yaml
      null
      null

      我必须编写逻辑来在_helpers.tpl中生成UUID。

编辑：在_helpers.tpl中定义它似乎不起作用--谢谢您指出这一点。

我查了一下，目前唯一的实现方法是将这两个清单（由--分隔）放到模板/下的同一文件中。请参阅以下示例，其中UUID在第一行中定义，然后在部署和状态集中使用：

{{- $mySharedUuid := uuidv4 -}}

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ include "uuid-test.fullname" . }}-1
  labels:
    {{- include "uuid-test.labels" . | nindent 4 }}
  annotations:
    my-uuid: {{ $mySharedUuid }}
spec:
...
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: {{ include "uuid-test.fullname" . }}-2
  labels:
    {{- include "uuid-test.labels" . | nindent 4 }}
  annotations:
    my-uuid: {{ $mySharedUuid }}
spec:
...

模板化后，输出为：

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: uuid-test-app-1
  labels:
    helm.sh/chart: uuid-test-0.1.0
    app.kubernetes.io/name: uuid-test
    app.kubernetes.io/instance: uuid-test-app
    app.kubernetes.io/version: "1.16.0"
    app.kubernetes.io/managed-by: Helm
  annotations:
    my-uuid: fe0346f5-a963-4ca1-ada0-af17405f3155
spec:

kind: StatefulSet
metadata:

    app.kubernetes.io/instance: uuid-test-app
    app.kubernetes.io/version: "1.16.0"
