Azure-app-config + spring-boot-kubernetes

Question

I'm trying to use azure's spring-cloud-azure-appconfiguration-config-web with spring-cloud-kubernetes-config. The idea is to define in kubernetes configmap application-kubernetes.yaml and also bootstrap-kubernetes.yaml. Inside bootstrap-kubernetes.yaml I'd like to define system variable which should be populated from kubernetes secrets.

kind: ConfigMap
apiVersion: v1
metadata:
  name: {{ template "chart.fullname" . }}
data:
  application-kubernetes.yaml: |-
    ...
  bootstrap-kubernetes.yaml: |-
    spring:
      cloud:
        azure:
          appconfiguration:
            stores:
              - connection-string: ${APP_CONFIGURATION_CONNECTION_STRING}

Unfortunately with this setup it's not possible to run appconfig because it fails on error:

Caused by: java.lang.IllegalArgumentException: At least one config store has to be configured.
    at org.springframework.util.Assert.notEmpty(Assert.java:467)
    at com.microsoft.azure.spring.cloud.config.AppConfigurationProperties.validateAndInit(AppConfigurationProperties.java:123)

So the question is, is it possible to set up such configuration where the configmap will be retrieved first and then the appconfig will be configured by properties used in configmap?
