How to access pod env variable in micronaut application.yaml file

[ankurjains]

I have configmap like this

apiVersion: v1
kind: ConfigMap
metadata:
  name: akhq
  namespace: monitoring
  labels:
    app: akhq
    version: 0.18.0
data:
  application.yml: |-
micronaut:
  security:
    enabled: true
akhq.security:
  basic-auth:
    - username: $username
      password: "$password"
      groups:
      - admin
    - username: $username  ## this pod shell variable i want to replace before akhq start reading this file
      password: "$password"
      groups:
      - reader
      clients-defaults:
        consumer:
          properties:
            isolation.level: read_committed

---

I am having secret map with username and password keys whose value is available in pod as secrekeyref in env variable.

Now I am trying to replace "username" pod env variable in application.yml which is not working when confimap writes application.yml in pod under /app location it prints string as it is ${myvar}. I want it to get replace from shell env variable before akhq start reading application.yaml.

Any placeholder i can use in application.yaml which micronaut framework can substitute in application.yaml before reading file. or how ?

Micronaut accept any env variable inside the configuration files.
You can use username: ${YOUR_ENV_USER}
