Spring Cloud kubernetes not loading config map

Question

I have created the 2 config map named personservice and personservice-dev.

I am running spring boot application with profile dev but it is not loading the right config map. This is what I see in logs of the pod which gets crashed.

Bootstrap:

spring:
  application:

Answer 1

You confused things. Your configmap is named personservice-dev and your application's name is personservice not personservice-dev, by default Spring Cloud K8S looks for configmap with name equals to spring.application.name and not spring.application.name-{profile}.

You have 2 ways to solve your problem:

1-Remove personservice-dev and in your personservice configmap:

kind: ConfigMap
apiVersion: v1
metadata:
  name: personservice
data:
  application.yml: |-
    p1:
      pa: blabla
    ---
    spring:
      profiles: dev
    p1:
      pa: blibli
    ---
    spring:
      profiles: prod
    p1:
      pa: blublu

2-Keep personservice-dev and personservice and define this in bootstrap.yml:

spring:
  cloud:
    kubernetes:
      config:
        name: ${spring.application.name} #This is optional
        sources:
          - name: ${spring.application.name}-${PROFILE} # Here you get your `personservice-dev` configmap
