Expose Kubernetes Ingress to LAN computers
I have computer A and B on LAN: A at IP 192.168.0.104 B at IP 192.168.0.110
On computer B I have a Kubernetes service with ingress: path hello host hello-node.com
minikube ip is 192.168.49.2 /etc/hosts has a line: 192.168.49.2 hello-node.com
On B I see the service response to hello-node.com/hello but not to 192.168.49.2/hello. On 192.168.49.2/hello I see 404 error from nginx.
How do I access either hello-node.com/hello or 192.168.49.2/hello from computer A?
I do not want to rely on any 3rd party service (load balancer etc)

You need to get the address of Computer B (the cluster ip) and then connect to it.
# Get the cluster "master" ip
$ kubectl cluster-info
Kubernetes master is running at https://<the desired ip/DNS record>......:443
# use the above ip to get the content of your service
curl -vsI <ip>/hello
You can access your minikube service from another machine by following steps from this github issue:
service_name=web # This is what you need to replace with your own service
service_port=$(minikube service $service_name --url | cut -d':' -f3)
ssh -i ~/.minikube/machines/minikube/id_rsa docker@$(minikube ip) -NL \*:${service_port}:0.0.0.0:${service_port}After that your service will be available under `<minikube's-host-ip>:<nodeport>
