Title: K8S Deployment Minimum Configuration Requirements

Introduction:
Kubernetes (K8S) is a popular container orchestration platform used to manage and deploy containerized applications. In this article, we will guide you through the process of deploying a Kubernetes cluster, focusing on the minimum configuration requirements. We will provide step-by-step instructions and code examples to get you started.

4. Configuring Kubernetes Nodes
5. Deploying a Sample Application

1. Prerequisites:
Before diving into the deployment process, ensure that you have the following prerequisites in place:
- A minimum of two physical or virtual machines running a Linux operating system (e.g., Ubuntu)
- Network connectivity between the machines
- Sudo or root access to the machines
- Basic knowledge of Linux and networking concepts

2. Installing Kubernetes Dependencies:
To deploy a Kubernetes cluster, we need to install a set of dependencies. Execute the following commands on all the machines participating in the cluster:

```bash
# Update the system packages
sudo apt-get update

# Install Docker
sudo apt-get install docker.io

# Enable and start the Docker service
sudo systemctl enable docker
sudo systemctl start docker

# Install kubeadm, kubelet, and kubectl
sudo apt-get install -y apt-transport-https curl
sudo curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
```

3. Setting up a Kubernetes Master:
The Kubernetes master is responsible for managing the cluster. Execute the following code on the intended master machine:

```bash
# Initialize the cluster with a specific pod network CIDR
sudo kubeadm init --pod-network-cidr=192.168.0.0/16

# Set up the kubeconfig file for root user access
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

# Deploy a pod network add-on (We will use Flannel in this example)
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
```

4. Configuring Kubernetes Nodes:
Kubernetes nodes are worker machines that run the actual application workloads. Execute the following code on all the worker nodes:

```bash
# Join the worker nodes to the cluster using the token provided during the master initialization
sudo kubeadm join : --token --discovery-token-ca-cert-hash
```

5. Deploying a Sample Application:
To ensure that the cluster is functioning correctly, let's deploy a sample application on the cluster. Use the following code:

```bash
# Deploy a sample Nginx web server
kubectl create deployment nginx --image=nginx

# Expose the deployment as a service
kubectl expose deployment nginx --port=80 --type=NodePort

# Check the status of the deployment
kubectl get deployments

# Access the application using any worker node's IP and NodePort
```

Conclusion:
Congratulations! You have successfully deployed a Kubernetes cluster with the minimum configuration requirements. This article provided step-by-step instructions, including code examples, for each stage of the deployment process. Remember to explore further and learn about advanced configuration options and security considerations to optimize your Kubernetes deployment. Happy container orchestration!
