This guide provides step-by-step instructions for installing Minikube. Earthly enhances CI/CD with efficient caching mechanisms. Check it out.

Creating kubernetes clusters locally is convenient: you don’t have to mess with production and it’s a low cost way for beginners who are learning Kubernetes to play around. Kubernetes has two tools you can use to create clusters locally which are: Minikube and Kind.

Minikube is a Kubernetes tool used to create clusters locally. This tool is developed by Kubernetes and is free. Unlike Kind which only uses Docker as a driver, Minikube allows you to use Hyper-v or any other virtual machine as the driver.

In this tutorial, you will learn how to install Minikube and create a cluster locally. In addition, you will learn how to secure your cluster using RBAC.


You need to have installed Kubectl before starting this tutorial.

Installing Minikube on Windows and Creating a Cluster Locally using Minikube

Use the following command to install Minikube on Windows using Powershell:

New-Item -Path 'c:\' -Name 'minikube' -ItemType Directory -Force
>> Invoke-WebRequest -OutFile 'c:\minikube\minikube.exe' -Uri '' -UseBasicParsing

After Minikube has been downloaded, the directory where it is been installed will be displayed:

Directory: C:\

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
d-----         3/19/2022  12:06 PM                minikube

Next, use the following command to add the binary to your path:

$oldPath = [Environment]::GetEnvironmentVariable('Path', [EnvironmentVariableTarget]::Machine)
if ($oldPath.Split(';') -inotcontains 'C:\minikube'){ `
  [Environment]::SetEnvironmentVariable('Path', $('{0};C:\minikube' -f $oldPath), [EnvironmentVariableTarget]::Machine) `

After adding the Minikube binary path, close PowerShell and then open it again using administrator mode whenever using Minikube in the next section.

Use the following command to check if Minikube has been installed successfully:

$ minikube version

If Minikube has been installed successfully you will get the version number as the output:

minikube version: v1.25.2
commit: 362d5fdc0a3dbee389b3d3f1034e8023e72bd3a7

Creating a Cluster Locally using Minikube

Use the following command to start a cluster:

$ minikube start 

The above cluster will set Hyper-v as the default driver if you are using Windows. However, you can specify your desired driver using the --driver flag and add Docker as your driver:

$ minikube start --driver=docker

When Minikube is creating the cluster, it will give you the Minikube version information installed on your computer and the Windows build. This information is critical if your want to use the Windows hyper-v as your driver because not all Windows versions have the hyper-V driver installed or enabled:

* minikube v1.25.2 on Microsoft Windows 10 Pro 10.0.19042 Build 19042
  - KUBECONFIG=C:\Users\VET KASI PHONE GSM.kube\config

If you are using an old version of Kubernetes, please go ahead and update it.

* Kubernetes 1.23.3 is now available. If you would like to upgrade, specify: --kubernetes-version=v1.23.3

This tutorial uses the hyper-V driver as the driver but you can also use the following tools as your driver:

  • Docker
  • VMware
* Using the hyperv driver based on existing profile

Minikube will go ahead and install all necessary cluster resources needed to start and run the cluster which are: a VM boot image with a version of Kubernetes preloaded.

The process will take roughly 6 minutes but this will vary depending on your internet speed and computing processor.

After the cluster has started successfully you will be prompted with the following message:

* Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

Use the following command to check your Kubernetes cluster status:

$ minikube status

You will the following output:

type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

Use the following information to get information about pods:

$ kubectl get po -A

You will get the following output:

NAMESPACE     NAME                    READY   STATUS   RESTARTS    AGE
kube-system   coredns-64897985d-8r2n8   1/1   Running  0           20m
kube-system   etcd-minikube             1/1   Running  0           21m
kube-system   kube-apiserver-minikube   1/1   Running  0           20m
kube-system   kube-proxy-zgzcf          1/1   Running  0           20m
kube-system   kube-scheduler-minikube   1/1   Running  0           21m
kube-system   storage-provisioner       1/1   Running  1 (19m ago) 20m

Using the Kubernetes Dashboard

The Kubernetes dashboard is used to display your Kubernetes cluster and application’s metrics. This metric is very useful when analyzing the health of your cluster.

Use the following command to display the Kubernetes dashboard:

$ minikube dashboard

It will open the following URL on your default browser:

* Opening in your default browser...

Since you have not created any object there will be no details displayed until you created an object:

Kubernetes dashboard

To get a functional dashboard, go ahead and create a service and deployment using the following command:

$ kubectl create deployment hello-minikube
$ kubectl expose deployment hello-minikube --type=NodePort --port=8080

You will get the following output:

deployment.apps/hello-minikube created
service/hello-minikube exposed

Check if the service has been created successfully:

$ kubectl get services hello-minikube

You will get the following details:

NAME        TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
hello-minikube NodePort   <none>   8080:30320/TCP   6m53s

Once deployed the Kubernetes dashboard will be filled with the deployment and service created information:

Securing Your Cluster With RBAC

Role-based access control(RBAC) is a Kubernetes technique that allows administrators and cluster owners to set specific access rights for Kubernetes resources in an organization. A ClusterRole is a rule that is set at a cluster scope while a Role applies to a specific namespace.

Creating a ClusterRole

Here is an example of a ClusterRole that gives the user the permission to get, watch, and list the secret resource at a cluster level. The resource field states what resource is being accessed while the verbs field specifies all the actions the user is allowed to take when using the secret resource.

kind: ClusterRole
  namespace: organization
  name: secret-reader
- apiGroups: [""] # "" indicates the core API group
  resources: ["secrets"]
  verbs: ["get", "watch", "list"]

Use the following command to create the ClusterRole:

$ kubectl create -f secret-reader.yaml 

You will get the following output when the ClusterRole has been created successfully: created


A RoleBinding or ClusterRoleBinding connects the Role/ClusterRole with an account or user that is being given the access rights. Verbs are a set of actions that the user is allowed to take when using a Kubernetes resource. For example: get, watch, list.

The following ClusterRoleBinding binds the ClusterRole you just created previously with the default service account. The ClusterRoleBinding also references the previous ClusterRole by stating the name, apiGroup, and the kind of the ClusterRole:

$ kubectl create clusterrolebinding secret-test \
  --clusterrole=secret-reader --serviceaccount=foo:default

You will get the following output: created

Using the following command to display the ClusterRoleBinding file that you have created:

$ kubectl get clusterrolebinding secret-test -o yaml

You will get the following output:

kind: ClusterRoleBinding
  creationTimestamp: "2022-04-25T22:39:07Z"
  name: secret-test
  resourceVersion: "64477"
  uid: a0ed20d1-c606-4b03-9364-1f09160243e6
  kind: ClusterRole
  name: secret-reader
- kind: ServiceAccount
  name: default
  namespace: foo

Creating a Service

A Kubernetes service exposes your cluster to external traffic. A service enables pod to pod communication. A service has an IP address and a port that is immutable.

You have to specify the service port and target port when creating a port. Create a file called service and add the following contents. This file will create a service called my-service:

apiVersion: v1
kind: Service
  name: my-service
  namespace: default
    app: nginx
  externalTrafficPolicy: Local
  - name: http
    port: 80
    protocol: TCP
    targetPort: 80
    app: nginx
  type: NodePort

Use the following command to create the service:

$ kubectl create -f service.yaml

You will get the following output:

service/my-service created

You can get more details about the service you just created using the following command:

$ kubectl get services

You will get the following output:

NAME          TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)      AGE
my-service    NodePort   <none>  80:30832/TCP   5m46s

Setting Cluster Resource Limits

Cloud infrastructure and Kubernetes are expensive; it’s either you’re deploying your cluster on the cloud using Google Kubernetes Engine or creating them locally. Costs will still incur because the cloud is expensive and so does memory. The consequence of not affording Kubernetes is noisy neighbors that hurt cluster performance.

Luckily, there is a mechanism called resource limit that enables you to set pod resource limits. These limits prohibit containers from overspending memory and CPU resources.

The resource limit and request mechanism have three fields which are

  • ephemeral-storage: This field specifies the ephemeral storage your container can use.
  • memory: This field sets the memory limit threshold or memory request for your container.
  • cpu: This field sets the CPU resource limits or requests for your container.

The following Pod has requests and limits for every container. The first container has a memory limit set to 128 Mi and the CPU resources set to 500m.

apiVersion: v1
kind: Pod
  name: pod-example
  - name: app
        memory: "64Mi"
        cpu: "250m"
        memory: "128Mi"
        cpu: "500m"

These changes will be applied when the Pod object is created or applied using the following command:

$ kubectl create -f pod-example.yaml

You will get the following output:

pod/pod-example created
