我有一个名为`application.yaml`的文件来自我的Spring配置。我想在ConfigMap中重用这个文件。我在Helm的`values.yaml`中定义了这些属性，然后在`configmap.yaml`中读取它们。
以下是所有的文件：
**application.yaml**
    invoice:
      catalog-service-uri: http://catalog-service
    spring:
      flyway:
        url: jdbc:postgresql://invoice-postgres/invoice_order
      r2dbc:
        url: r2dbc:postgresql://invoice-postgres/invoice_order
      rabbitmq:
        host: invoice-rabbitmq
      security:
        oauth2:
          resourceserver:
            jwt:
              issuer-uri: http://ecomm-keycloak/realms/EcommRealm
**values.yaml**
    configMapData:
      application.yaml: |-
        invoice:
          catalog-service-uri: http://catalog-service
        spring:
          flyway:
            url: jdbc:postgresql://invoice-postgres/invoice_order
          r2dbc:
            url: r2dbc:postgresql://invoice-postgres/invoice_order
          rabbitmq:
            host: invoice-rabbitmq
          security:
            oauth2:
              resourceserver:
                jwt:
                  issuer-uri: http://ecomm-keycloak/realms/EcommRealm
**configmap.yaml**
    apiVersion: v1
    kind: ConfigMap
    metadata:
      name: order-config
      labels:
        app: order-service
    data:
      {{- range $key, $value := .Values.configMapData }}
        {{ $key }}: |-
          {{ $value | indent 4 }}
      {{- end }}
使用这个配置，我得到了错误：
**msg: 'error unmarshalling resource: error converting YAML to JSON: yaml: line 7:
    did not find expected node content'**
这个配置有什么问题？
有没有更好的方法来做同样的事情？
任何帮助将不胜感激。
谢谢
