I have an ASP.NET Core app that I want to configure with HTTPS in my local kubernetes clustur using minikube.

The deployment yaml file is:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: kube-volume
  labels:
    app: kube-volume-app
spec:
  replicas: 1
  selector: 
    matchLabels:
      component: web
  template:
    metadata: 
      labels:
        component: web
    spec:
      containers:
        - name: ckubevolume
          image: kubevolume
          imagePullPolicy: Never
          ports:
            - containerPort: 80
            - containerPort: 443
          env:
            - name: ASPNETCORE_ENVIRONMENT
              value: Development
            - name: ASPNETCORE_URLS
              value: https://+:443;http://+:80
            - name: ASPNETCORE_HTTPS_PORT
              value: '443'
            - name: ASPNETCORE_Kestrel__Certificates__Default__Password
              value: mypass123
            - name: ASPNETCORE_Kestrel__Certificates__Default__Path
              value: /app/https/aspnetapp.pfx
          volumeMounts:
            - name: ssl
              mountPath: "/app/https"
      volumes:
        - name: ssl
          configMap:
            name: game-config

You can see i have added environment variables for https in yaml file.

I also created a service for this deployment. The yaml file of the service is:

apiVersion: v1
kind: Service
metadata:
  name: service-1
spec:
  type: NodePort
  selector:
    component: web
  ports:
    - name: http
      protocol: TCP
      port: 100
      targetPort: 80
    - name: https
      protocol: TCP
      port: 200
      targetPort: 443

But unfortunately the app is not opening by the service when I run the minikube service service-1 command.

However when I remove the env variables for https then the app is opening by the service. These are the lines which when I remove the app opens:

- name: ASPNETCORE_URLS
  value: https://+:443;http://+:80
- name: ASPNETCORE_HTTPS_PORT
  value: '443'
- name: ASPNETCORE_Kestrel__Certificates__Default__Password
  value: mypass123
- name: ASPNETCORE_Kestrel__Certificates__Default__Path
  value: /app/https/aspnetapp.pfx

I also confirmed with the shell that the certificate is present in the /app/https folder.

Whay I am doing wrong?
