Exposing a Kubernetes service outside the cluster – Nginx

I am trying to expose a simple grafana service exposed outside the cluster. Here is what i have done so far in terms of troubleshooting and researching before posting here and little bit of details of my setup.

Grafana deployment YAML

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: grafana
  name: grafana
spec:
  selector:
    matchLabels:
      app: grafana
  template:
    metadata:
      labels:
        app: grafana
    spec:
      replicas: 2
      securityContext:
        fsGroup: 472
        supplementalGroups:
          - 0
      containers:
        - name: grafana
          image: 'grafana/grafana:8.0.4'
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 3000
              name: http-grafana
              protocol: TCP
          env:
            - name: GF_DATABASE_CA_CERT_PATH
              value: /etc/grafana/BaltimoreCyberTrustRoot.crt.pem
          readinessProbe:
            failureThreshold: 3
            httpGet:
              path: /robots.txt
              port: 3000
              scheme: HTTP
            initialDelaySeconds: 10
            periodSeconds: 30
            successThreshold: 1
            timeoutSeconds: 2
          livenessProbe:
            failureThreshold: 3
            initialDelaySeconds: 30
            periodSeconds: 10
            successThreshold: 1
            tcpSocket:
              port: 3000
            timeoutSeconds: 1
          resources:
            requests:
              cpu: 250m
              memory: 750Mi
          volumeMounts:
            - name: grafana-configmap-pv
              mountPath: /etc/grafana/grafana.ini
              subPath: grafana.ini
            - name: grafana-pv
              mountPath: /var/lib/grafana
            - name: cacert
              mountPath: /etc/grafana/BaltimoreCyberTrustRoot.crt.pem
              subPath: BaltimoreCyberTrustRoot.crt.pem
      volumes:
        - name: grafana-pv
          persistentVolumeClaim:
            claimName: grafana-pvc
        - name: grafana-configmap-pv
          configMap:
            name: grafana-config
        - name: cacert
          configMap:
            name: mysql-cacert

Grafana Service yaml

apiVersion: v1
kind: Service
metadata:
  name: grafana
spec:
  type: ClusterIP
  ports:
    - port: 3000
      protocol: TCP
      targetPort: http-grafana
  clusterIP: 10.7.2.57
  selector:
    app: grafana
  sessionAffinity: None

I have nginx installed as Ingress controller. Here is the YAML for nginx controller service

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx-controller
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/version: 1.0.0
    helm.sh/chart: ingress-nginx-4.0.1
spec:
  ports:
    - name: http
      protocol: TCP
      appProtocol: http
      port: 80
      targetPort: http
      nodePort: 32665
    - name: https
      protocol: TCP
      appProtocol: https
      port: 443
      targetPort: https
      nodePort: 32057
  selector:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/name: ingress-nginx
  clusterIP: 10.7.2.203
  clusterIPs:
    - 10.7.2.203
  type: NodePort
  sessionAffinity: None
  externalTrafficPolicy: Cluster
status:
  loadBalancer: {}

Ingress resource yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: grafana-ingress
spec:
  rules:
  - host: test.grafana.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: grafana
            port:
              number: 3000

The ingress ip 10.7.0.5 is not accessible at all. I have tried redploying the resources various times. The grafana POD ips are accessible with port 3000, i am able to login etc but just been unable to access grafana through the nginx load balancer. What am i missing?
