1) I have SSL certs generated on AWS

apiVersion: v1
kind: Service
metadata:
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-backend-protocol: tcp
    service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: "3600"
    service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: '*'
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:...fa5298fc
    service.beta.kubernetes.io/aws-load-balancer-ssl-ports: https
  labels:
    k8s-addon: ingress-nginx.addons.k8s.io
  name: ingress-nginx-lb-svc
  # namespace: ingress-nginx
spec:
  externalTrafficPolicy: Cluster
  ports:
  - name: https
    port: 443
    protocol: TCP
    targetPort: http
  - name: http
    port: 80
    protocol: TCP
    targetPort: http
  selector:
    app: nginx-ingress-control-pod
  type: LoadBalancer

2) then I have nginx controller pod

apiVersion: v1
kind: ReplicationController
metadata:
  name: nginx-ingress-control-pod
  labels:
    app: nginx-ingress-control-pod
spec:
  replicas: 1
  selector:
    app: nginx-ingress-control-pod
  template:
    metadata:
      labels:
        app: nginx-ingress-control-pod
    spec:
      containers:
      - image: nginxdemos/nginx-ingress:1.0.0
        imagePullPolicy: Always
        name: nginx-ingress-control-pod
        ports:
        - name: http
          containerPort: 80
          hostPort: 80
        #- name: https
        #  containerPort: 443
        #  hostPort: 443
        env:
        - name: POD_NAMESPACE
          valueFrom:
            fieldRef:
              fieldPath: metadata.namespace
        # Uncomment the lines below to enable extensive logging and/or customization of
        # NGINX configuration with configmaps
        args:
         #- -v=3
         #- -nginx-configmaps=$(POD_NAMESPACE)/nginx-config
         #- -default-server-tls-secret=$(POD_NAMESPACE)/web-secret

3) lastly I am using helm to deploy grafana and prometheus (this setup works when accessing via NodePort)

I just can not figure out setup with ELB and ingress. Btw ingress is a part of grafana deployment which is correctly created
