Spring Cloud kubernetes not loading config map - spring

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.

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
