How to install and configure Minikube on Ubuntu 21.10

Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a VM on your local machine. Kubernetes quickly set up a local Kubernetes cluster on Linux, Windows, and macOS.

It is always advisable before diving into Kubernetes, you will need a minimal Kubernetes setup. Such a setup should spin up fast and integrate well with other tools.

Minikube is the best fit because of the following:

  • It runs on Windows, Linux and MacOS.
  • It supports the latest Kubernetes release
  • It supports multiple container runtimes i.e Containerd, KVM, Docker, Podman etc
  • It has supports for adbvanced features such as Load balancing, Featuregates and filesystems mounts.
  • It has support for Addons. Addons being a marketplace for developers to share configurations for running services on Minikube.
  • It supports CI environments


To run Kubernetes effectively you need to allocate the following to Minikube on your system.

  • 2 CPUs or more
  • 2 GB of memory
  • 20 GB or more of free disk space
  • Reliable internet connections.
  • Conatiner or virtual machine manager such as Docker, KVM, Podman, Virtual Box etc.

Install Minikube on Ubuntu 21.10

Let’s now dive into installing and playing with Kubernetes. I am going to be using Docker for running Kubernetes, You can spin up using Podman, Virtualbox, or KVM whichever you understand well.

1. Run system updates

To make our repositories up to date run total system updates with the following command;

$ sudo apt update && apt upgrade -y

2. Install Docker on Ubuntu 21.10

Docker container acts as a base for installing Minikube. Kubernetes depends on docker to run. So use the following command to install docker if you have not already installed it. For complete docker install check this out.

$ sudo apt install

Once installed, add your local user to it because Minikube doesn’t run as a root.

Lets add new user with the following command.

$ useradd --create-home nextgentips
$ sudo usermod -aG docker nextgentips

3. Download Minikube

We are going to download the Minikube binary from the Minikube Library.

$ curl -LO
sudo install minikube-linux-amd64 /usr/local/bin/minikube

Now that we have installed Minikube, you can check the version of it with the following command.

$ minikube version
minikube version: v1.24.0
commit: 76b94fb3c4e8ac5062daf70d60cf03ddcc0a741b

You now need to install kubectl

4. Install Kubectl

Kubectl is a command-line tool for controlling Kubernetes clusters. To install kubectl run the following command.

curl -LO`curl -s`/bin/linux/amd64/kubectl

make sure you make it executable with the following command.

$ chmod +x ./kubectl

Then you will have to move it in your $PATH

sudo mv ./kubectl /usr/local/bin/kubectl

5. Start Minikube on Ubuntu 21.10

To start minikube run minikube start command.

$ minikube start

You will get the following output.

Check basic Minikube commands

Check Minikube cluster-info

$ kubectl cluster-info
Kubernetes control plane is running at
CoreDNS is running at

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.


We have successfully installed Minikube on Ubuntu 21.10. For more information check Minikube documentation.
