Any help much appreciated , I have couple of spring boot application running in aks with default profile , i am trying to change the profile from my deployment.yaml using helm

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ include "helm-chart.fullname" . }}
  labels:
    app.kubernetes.io/name: {{ include "helm-chart.name" . }}
    helm.sh/chart: {{ include "helm-chart.chart" . }}
    app.kubernetes.io/instance: {{ .Release.Name }}
    app.kubernetes.io/managed-by: {{ .Release.Service }}
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app.kubernetes.io/name: {{ include "helm-chart.name" . }}
      app.kubernetes.io/instance: {{ .Release.Name }}
  template:
    metadata:
      labels:
        app.kubernetes.io/name: {{ include "helm-chart.name" . }}
        app.kubernetes.io/instance: {{ .Release.Name }}
    spec:
      containers:
        - name: {{ .Chart.Name }}
          image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
          imagePullPolicy: {{ .Values.image.pullPolicy }}
             
          ports:
            - name: http
              containerPort: 8080
              protocol: TCP
          env:
          - name: SPRING_PROFILES_ACTIVE
            value: "dev"

what i end up is my pod is been put to crashloopbackoff state saying

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

2022-01-12 12:42:49.054 ERROR 1 --- main o.s.b.d.LoggingFailureAnalysisReporter :

APPLICATION FAILED TO START

Description:

The Tomcat connector configured to listen on port 8207 failed to start. The port may already be in use or the connector may be misconfigured.

I tried to delete the existing pod and service for the application and did a fresh deploy i still get the same error ..

methods tried :(in all methods docker file is created , pod is created , application in pod is setup to dev profile but the thing is it not able to start the application with the above error , when i remove the profile setting , every thing is workly perfectly fine expect the fact is the application is set to default profile)

1) in docker file :

option a. CMD "java","-jar","/app.jar", "--spring.profiles.active=dev" option b. CMD "java","-jar","-Dspring.profiles.active=dev","/app.jar"

2) changed in deployment.yml as mentioned above

ps : i dont have property file in my application on src/main/resources , i have only application-(env).yml files there .

The idea is to set the profile first and based on the profile the application_(env).yml has to be selected

output from helm

Release "app" has been upgraded. Happy Helming!
