Kubernetes Ingress Controller Error when exposing application - kubernetes

Question

I'm trying to expose my backend API service using the nginx Ingress controller. Here is the Ingress service that I have defined:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: plant-simulator-ingress
namespace: plant-simulator-ns
annotations:
ingress.kubernetes.io/enable-cors: "true"
kubernetes.io/ingress.class: nginx
# nginx.ingress.kubernetes.io/rewrite-target: /
prometheus.io/scrape: 'true'
prometheus.io/path: /metrics
prometheus.io/port: '80'
spec:
rules:
- host: grafana.local
http:
paths:
- backend:
serviceName: grafana-ip-service
servicePort: 8080
- host: prometheus.local
http:
paths:
- backend:
serviceName: prometheus-ip-service
servicePort: 8080
- host: plant-simulator.local
http:
paths:
- backend:
serviceName: plant-simulator-service
servicePort: 9000
The plant-simulator-service is defined as a service:
apiVersion: v1
kind: Service
metadata:
name: plant-simulator-service
namespace: plant-simulator-ns
labels:
name: plant-simulator-service
spec:
ports:
- port: 9000
targetPort: 9000
protocol: TCP
name: plant-simulator-service-port
selector:
app: plant-simulator
type: LoadBalancer
I successfully deployed this on my Minikube and here is the set of pods running:
Joes-MacBook-Pro:~ joesan$ kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-6955765f44-cvblh 1/1 Running 0 39m

plant-simulator-ns plant-simulator-6d46dc89cb-xsjgv 1/1 Running 0 65s
Here is the list of services:
Joes-MacBook-Pro:~ joesan$ minikube service list
|--------------------|-------------------------|-----------------------------|-----|
| NAMESPACE | NAME | TARGET PORT | URL |
|--------------------|-------------------------|-----------------------------|-----|
| default | kubernetes | No node port |
| kube-system | kube-dns | No node port |
| plant-simulator-ns | memcached | No node port |
| plant-simulator-ns | plant-simulator-service | http://192.168.99.103:32638 |
|--------------------|-------------------------|-----------------------------|-----|
What I wanted to achieve is that my application backend is reachable via the dns entry that I have configured in my Ingress -
plant-simulator.local
Any ideas as to what I'm missing?

OP reported the case was solved by adding the IP and Hostname in the /etc/hosts
$ cat /etc/hosts
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
192.168.99.103 plant-simulator.local
