how to access istio mesh from browser - kubernetes

Question

I'm trying to inject istio into my kubernetes in minikube environment on my local ubuntu 16.04 system. this is my deployment yaml
apiVersion: extensions/v1beta1
kind: Deployment

I've enabled automatic sidecar injection and ran $kubect apply -f deployment.yaml
I've installed istio via this method
here's my istio installation details :

Here's my gateway yaml
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: ms-gateway
spec:
selector:
istio: ingressgateway # use istio default controller
servers:
- port:
number: 80
name: http
protocol: HTTP
hosts:
- "*"
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: mater-slave
spec:
hosts:
- "*"
gateways:
- ms-gateway
http:
- match:
- uri:
prefix: /master
route:
- destination:
host: nodejs-master
port:
number: 8080
I've applied my gateway using kubectl apply command. and trying to access it using
http://($minikube ip):kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(#.name=="http2")].nodePort}'/master
i.e http://192.168.99.100:31380/master
but I'm getting connection refused error. Someone please help.
thanks in advance.

Maybe it's the name of the service port. It should be "tcp-*". https://istio.io/docs/setup/kubernetes/additional-setup/requirements/
