How to Install Minikube in Amazon Linux

 Kubernetes is a container management tool. It is Donated by Google to the Opensource community. It has now become the defacto container management tool of choice.

In Kubernetes setup we have one master node and multiple worker nodes. The worker-nodes are then managed from the master node, thus ensuring that the cluster is managed from a central point.

You can also deploy a single-node Kubernetes cluster. You can use Minikube, which is a tool that runs a single-node Kubernetes cluster in a virtual machine on your node.

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

Docker Installation

1. Launch an instance from an Amazon Linux 2 or Amazon Linux AMI.

2. Connect to your instance.

3. Updates the packages and package caches you have installed on your instance.

yum update -y

4. Install the latest Docker Engine packages.

Amazon Linux 2

amazon-linux-extras install docker

Amazon Linux.

yum install docker

5. Start the Docker service.

service docker start

6. "sudo docker " Add to the group so you can run Docker commands without using "ec2-user".

usermod -a -G docker ec2-user

Install Docker Amazon Linux

Install Conntrack:

 yum install conntrack

minikube_install_amazon_conntrack

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

OR 
wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
chmod +x minikube-linux-amd64
mv minikube-linux-amd64 /usr/local/bin/minikube
minikube version

install minikube_amazon_linux

Start your cluster

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

minikube start --vm-driver=none

minikube_install_amazon_linux2

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
