Hello Minikube

This tutorial shows you how to run a sample app on Kubernetes using minikube. The tutorial provides a container image that uses NGINX to echo back all the requests.


  • Deploy a sample application to minikube.
  • Run the app.
  • View application logs.

Before you begin

This tutorial assumes that you have already set up minikube. See Step 1 in minikube start for installation instructions.

You also need to install kubectl. See Install tools for installation instructions.

Create a minikube cluster

minikube start

Open the Dashboard

Open the Kubernetes dashboard. You can do this two different ways:

Open a new terminal, and run:

# Start a new terminal, and leave this running.
minikube dashboard

Now, switch back to the terminal where you ran minikube start.

If you don't want minikube to open a web browser for you, run the dashboard subcommand with the --url flag. minikube outputs a URL that you can open in the browser you prefer.

Open a new terminal, and run:

# Start a new terminal, and leave this running.
minikube dashboard --url

Now, you can use this URL and switch back to the terminal where you ran minikube start.

Create a Deployment

A Kubernetes Pod is a group of one or more Containers, tied together for the purposes of administration and networking. The Pod in this tutorial has only one Container. A Kubernetes Deployment checks on the health of your Pod and restarts the Pod's Container if it terminates. Deployments are the recommended way to manage the creation and scaling of Pods.

  1. Use the kubectl create command to create a Deployment that manages a Pod. The Pod runs a Container based on the provided Docker image.

    # Run a test container image that includes a webserver
    kubectl create deployment hello-node --image=registry.k8s.io/e2e-test-images/agnhost:2.39 -- /agnhost netexec --http-port=8080
  2. View the Deployment:

    kubectl get deployments

    The output is similar to:

    hello-node   1/1     1            1           1m

    (It may take some time for the pod to become available. If you see "0/1", try again in a few seconds.)

  3. View the Pod:

    kubectl get pods

    The output is similar to:

    NAME                          READY     STATUS    RESTARTS   AGE
    hello-node-5f76cf6ccf-br9b5   1/1       Running   0          1m
  4. View cluster events:

    kubectl get events
  5. View the kubectl configuration:

    kubectl config view
  6. View application logs for a container in a pod (replace pod name with the one you got from kubectl get pods).

    kubectl logs hello-node-5f76cf6ccf-br9b5

    The output is similar to:

    I0911 09:19:26.677397       1 log.go:195] Started HTTP server on port 8080
    I0911 09:19:26.677586       1 log.go:195] Started UDP server on port  8081

Create a Service

By default, the Pod is only accessible by its internal IP address within the Kubernetes cluster. To make the hello-node Container accessible from outside the Kubernetes virtual network, you have to expose the Pod as a Kubernetes Service.

  1. Expose the Pod to the public internet using the kubectl expose command:

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

    The --type=LoadBalancer flag indicates that you want to expose your Service outside of the cluster.

    The application code inside the test image only listens on TCP port 8080. If you used kubectl expose to expose a different port, clients could not connect to that other port.

  2. View the Service you created:

    kubectl get services

    The output is similar to:

    NAME         TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
    hello-node   LoadBalancer   <pending>     8080:30369/TCP   21s
    kubernetes   ClusterIP       <none>        443/TCP          23m

    On cloud providers that support load balancers, an external IP address would be provisioned to access the Service. On minikube, the LoadBalancer type makes the Service accessible through the minikube service command.

  3. Run the following command:

    minikube service hello-node

    This opens up a browser window that serves your app and shows the app's response.

Enable addons

The minikube tool includes a set of built-in addons that can be enabled, disabled and opened in the local Kubernetes environment.

  1. List the currently supported addons:

    minikube addons list

    The output is similar to:

    addon-manager: enabled
    dashboard: enabled
    default-storageclass: enabled
    efk: disabled
    freshpod: disabled
    gvisor: disabled
    helm-tiller: disabled
    ingress: disabled
    ingress-dns: disabled
    logviewer: disabled
    metrics-server: disabled
    nvidia-driver-installer: disabled
    nvidia-gpu-device-plugin: disabled
    registry: disabled
    registry-creds: disabled
    storage-provisioner: enabled
    storage-provisioner-gluster: disabled
  2. Enable an addon, for example, metrics-server:

    minikube addons enable metrics-server

    The output is similar to:

    The 'metrics-server' addon is enabled
  3. View the Pod and Service you created by installing that addon:

    kubectl get pod,svc -n kube-system

    The output is similar to:

    NAME                                        READY     STATUS    RESTARTS   AGE
    pod/coredns-5644d7b6d9-mh9ll                1/1       Running   0          34m
    pod/coredns-5644d7b6d9-pqd2t                1/1       Running   0          34m
    pod/metrics-server-67fb648c5                1/1       Running   0          26s
    pod/etcd-minikube                           1/1       Running   0          34m
    pod/influxdb-grafana-b29w8                  2/2       Running   0          26s
    pod/kube-addon-manager-minikube             1/1       Running   0          34m
    pod/kube-apiserver-minikube                 1/1       Running   0          34m
    pod/kube-controller-manager-minikube        1/1       Running   0          34m
    pod/kube-proxy-rnlps                        1/1       Running   0          34m
    pod/kube-scheduler-minikube                 1/1       Running   0          34m
    pod/storage-provisioner                     1/1       Running   0          34m
    NAME                           TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)             AGE
    service/metrics-server         ClusterIP    <none>        80/TCP              26s
    service/kube-dns               ClusterIP      <none>        53/UDP,53/TCP       34m
    service/monitoring-grafana     NodePort     <none>        80:30002/TCP        26s
    service/monitoring-influxdb    ClusterIP   <none>        8083/TCP,8086/TCP   26s
  4. Check the output from metrics-server:

    kubectl top pods

    The output is similar to:

    NAME                         CPU(cores)   MEMORY(bytes)   
    hello-node-ccf4b9788-4jn97   1m           6Mi             

    If you see the following message, wait, and try again:

    error: Metrics API not available
  5. Disable metrics-server:

    minikube addons disable metrics-server

    The output is similar to:

    metrics-server was successfully disabled

Clean up

Now you can clean up the resources you created in your cluster:

kubectl delete service hello-node
kubectl delete deployment hello-node

Stop the Minikube cluster

minikube stop

Optionally, delete the Minikube VM:

# Optional
minikube delete

If you want to use minikube again to learn more about Kubernetes, you don't need to delete it.


This page covered the basic aspects to get a minikube cluster up and running. You are now ready to deploy applications.
