How to visualize my web application with browser using Kubernetes Nginx Ingress? - kubernetes-ingress

Question

I am following this web site to develop an API with Nginx Ingress. When I use curl command it works !
curl -v -k -H "Host: myServiceA.foo.org" http:<IP_ADDRESS_INGRESS_NGINX>:80
Now I would like to use a browser like Chrome or Firefox but I don't find any way to do it knowing that http:<IP_ADDRESS_INGRESS_NGINX>:80 doesn't work without header.
Do you know how to do please ?
Regards

It's not working because you've configured the host field in ingress yaml.
Using the same yaml from Nginx docs you've posted:
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: ingress-myServiceA
annotations:
# use the shared ingress-nginx
kubernetes.io/ingress.class: "nginx"
spec:
rules:
- host: myServiceA.foo.org <== HERE
http:
paths:
- path: /
backend:
serviceName: myServiceA
servicePort: 80
The ingress will only accept the connection and forwarding the request to your service if the request contains the host myServiceA.foo.org.
You could test it editing the /etc/hosts of your machine e pointing to the nginx ingress ip:
File /etc/hosts
<INGRESS_IP> myServiceA.foo.org
Or another option is remove the field host in this way the ingress will accept requests coming from the Nginx ingress ip, like this yaml:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: example-ingress
spec:
rules:
- http:
paths:
- path: /
backend:
serviceName: echo-svc
servicePort: 80
