Configmap in helm chart user-data

Question

这是我的configmap模板，它从我的用户数据文件中获取数据，如values.yaml。我有两个应用程序，App-A &App-B。ip由App-B分配，在App-A中，只有App-B分配ip的接口被配置。

CONFIGMAP模板:

apiVersion: v1
kind: ConfigMap
metadata:
namespace: {{$namespace}}
name: {{$pod}}-configmap
data:
user-data: |
{{- $userdata := (cat $pod "-userdata"|nospace)}}
{{ $.Files.Get $userdata | nindent 4}}

Answer 1

我不知道你的ip数据源是否来自值。或者是从其他文件中读取的，上面不是很清楚，所以这里有两个解决方案。
