How to Install Minikube in Ubuntu

 minikube is local Kubernetes, focusing on making it easy to learn and develop for Kubernetes.

All you need is Docker (or similarly compatible) container or a Virtual Machine environment, and Kubernetes is a single command away: minikube start

What you’ll need

• 2 CPUs or more
• 2GB of free memory
• 20GB of free disk space
• Internet connection
• Container or virtual machine manager, such as: Docker, Hyperkit, Hyper-V, KVM, Parallels, Podman, VirtualBox, or VMWare

Minkube Installation

Binary download

 curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
 sudo install minikube-linux-amd64 /usr/local/bin/minikube

Debian package

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
sudo dpkg -i minikube_latest_amd64.deb

Start your cluster

From a terminal with administrator access (but not logged in as root), run:

minikube start

If you already have kubectl installed, you can now use it to access your shiny new cluster:

kubectl get po -A

How to Install kubectl on Linux

Alternatively, minikube can download the appropriate version of kubectl, if you don’t mind the double-dashes in the command-line:

minikube kubectl -- get po -A

Deploy applications

Create a sample deployment and expose it on port 8080:

kubectl create deployment hello-minikube --image=k8s.gcr.io/echoserver:1.4
kubectl expose deployment hello-minikube --type=NodePort --port=8080

It may take a moment, but your deployment will soon show up when you run:

kubectl get services hello-minikube

The easiest way to access this service is to let minikube launch a web browser for you:

minikube service hello-minikube

Alternatively, use kubectl to forward the port:

kubectl port-forward service/hello-minikube 7080:8080

Tada! Your application is now available at http://localhost:7080/

Manage your cluster

Pause Kubernetes without impacting deployed applications:

minikube pause

Halt the cluster:

minikube stop

Delete all of the minikube clusters:

minikube delete --all
