LoadBalancer access

How to access a LoadBalancer service in minikube


A LoadBalancer service is the standard way to expose a service to the internet. With this method, each service gets its own IP address.

Using minikube tunnel

Services of type LoadBalancer can be exposed via the minikube tunnel command. It will run in a separate terminal until Ctrl-C is hit.


Run tunnel in a separate terminal

it will ask for password.

minikube tunnel

minikube tunnel runs as a separate daemon, creating a network route on the host to the service CIDR of the cluster using the cluster’s IP address as a gateway. The tunnel command exposes the external IP directly to any program running on the host operating system.

tunnel output example
    machine: minikube
    pid: 39087
    route: ->
    minikube: Running
    services: [hello-minikube]
        minikube: no errors
        router: no errors
        loadbalancer emulator: no errors

Create a kubernetes deployment

kubectl create deployment hello-minikube1 --image=k8s.gcr.io/echoserver:1.4

Create a kubernetes service type LoadBalancer

kubectl expose deployment hello-minikube1 --type=LoadBalancer --port=8080

Check external IP

kubectl get svc
$ kc get svc
NAME              TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)          AGE
hello-minikube1   LoadBalancer   8080:30791/TCP   40s

note that without minikube tunnel, kubernetes would be showing external IP as “pending”.

Try in your browser

open in your browser (make sure there is no proxy set)


Each service will get its own external ip.

DNS resolution (experimental)

If you are on macOS, the tunnel command also allows DNS resolution for Kubernetes services from the host.

Cleaning up orphaned routes

If the minikube tunnel shuts down in an abrupt manner, it may leave orphaned network routes on your system. If this happens, the ~/.minikube/tunnels.json file will contain an entry for that tunnel. To remove orphaned routes, run:

minikube tunnel --cleanup

Avoiding password prompts

Adding a route requires root privileges for the user, and thus there are differences in how to run minikube tunnel depending on the OS. If you want to avoid entering the root password, consider setting NOPASSWD for “ip” and “route” commands:
