How to configure load balancer in kubernetes ?

Answer 1

In the deployment file keep the type as LoadBalancer and then create a service for it.

Execute this command to get the ip of your load balancer:

kubectl describe services example-service

You'll see something like this:

  Name:                   example-service
    Namespace:              default
    Labels:                 <none>
    Annotations:            <none>
    Selector:               app=example
    Type:                   LoadBalancer
    IP:                     10.67.252.103
    LoadBalancer Ingress:   123.45.67.89
    Port:                   <unnamed> 80/TCP
    NodePort:               <unnamed> 32445/TCP
    Endpoints:              10.64.0.4:80,10.64.1.5:80,10.64.2.4:80
    Session Affinity:       None
    Events:                 <none>

That'll be your load balancer's IP
