Document how to use Host IP as external IP in minikube for LoadBalancer type Service

[tamalsaha]

What I do in this case for voyager is use a service type ClusterIP with an ip fixed (like 10.0.0.150) then create a route to it from my machine

Works with Mac and minikube on virtualbox/vmware providers

sudo route -n delete ${K8S_NETWORK} > /dev/null 2>&1 
  sudo route -n add ${K8S_NETWORK} $(minikube ip)
  interface=$(ifconfig 'bridge0' | grep member | awk '{print $2}' | xargs | awk '{print $1}')
  sudo ifconfig bridge0 -hostfilter ${interface}

Linux version

 sudo ip route add ${K8S_NETWORK} via $(minikube ip)```

Thanks @david92rl for this method.

K8S_NETWORK usually is 10.0.0.0/24 but it's worth to double check always.
On Linux version adding sudo ip route del ${K8S_NETWORK} at the beginning will prevent you from errors if the rule is already set.
