How to install Kubernetes in Kali Linux?

Kubernetes is a popular open-source container orchestration system that helps in automating the deployment, scaling, and management of containerized applications. In this tutorial, we will walk you through the steps on how to install Kubernetes in Kali Linux.

Before we proceed with the installation, let’s ensure that the following requirements are met:

  • A machine with Kali Linux installed
  • A user account with sudo privileges
  • At least 2 GB of RAM and 2 CPU cores

Step 1: Update the system

Before installing any new software, it’s recommended to update the system to the latest packages. Open the terminal and type the following command:

sudo apt update && sudo apt upgrade -y

Step 2: Install Docker

Kubernetes uses Docker to manage and run containers. To install Docker, run the following commands:

sudo apt install -y
sudo systemctl start docker
sudo systemctl enable docker

To verify if Docker is running properly, run the following command:

sudo docker info

Step 3: Install Kubernetes

There are several ways to install Kubernetes in Kali Linux. In this tutorial, we will use the kubeadm utility to install Kubernetes.

Run the following commands to install kubeadm, kubelet, and kubectl:

sudo apt-get update && sudo apt-get install -y apt-transport-https curl
curl -s | sudo apt-key add -
echo "deb kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl

Step 4: Configure Kubernetes

Now, we will initialize the Kubernetes cluster using kubeadm. Run the following command:

sudo kubeadm init

This will take some time to complete. Once the initialization is done, you will see a message with the command to join the nodes to the cluster.

Save this command as you will need it later when you want to add worker nodes to the cluster.

Step 5: Configure kubectl

Kubectl is a command-line tool that allows you to interact with the Kubernetes cluster. To configure kubectl, run the following commands:

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

Step 6: Deploy a pod

To verify if Kubernetes is working properly, we will deploy a pod.

Create a file called pod.yaml with the following content:

apiVersion: v1
kind: Pod
  name: myapp
    app: myapp
  - name: myapp
    image: nginx
    - containerPort: 80

Now, run the following command to deploy the pod:

kubectl apply -f pod.yaml

To verify if the pod is running, run the following command:

kubectl get pods

You should see the myapp pod running.

Congratulations! You have successfully installed Kubernetes in Kali Linux and deployed your first pod.
