Local Cluster Deployment of Kubernetes: A Hands-On Project

Prerequisite Installation

1. Docker

2. Minikube

After Installing, run

kubectl get nodes

kubectl dashboard

Understanding Minikube

Minikube is an open-source tool designed to help you run Kubernetes locally on your computer. Kubernetes is a powerful platform used for managing containerized applications across a cluster of machines, but setting up a full Kubernetes cluster can be complex and resource-intensive. Minikube simplifies this by running a single-node Kubernetes cluster inside a virtual machine (VM) on your laptop or desktop. This setup allows developers to experiment with Kubernetes and develop with it day-to-day, without needing to deploy to a full Kubernetes environment.

System Requirements

• 2 CPUs or more

• 2GB of free memory

• 20GB of free disk space

• Internet connection

• Container or virtual machine manager, such as: Docker, QEMU, Hyperkit, Hyper-V, KVM, Parallels, Podman, VirtualBox, or VMware Fusion/Workstation

Steps to Deploy a Sample Application

After setting up Minikube, follow these steps to deploy a sample application:

1. Create a Deployment

    kubectl create deployment hello-minikube --image=kicbase/echo-server:1.0
   

   This command creates a deployment named hello-minikube using the kicbase/echo-server:1.0 image.

2. Expose the Deployment

    kubectl expose deployment hello-minikube --type=NodePort --port=8080
   

   This command exposes the deployment as a service, making it accessible via a NodePort on port 8080.

3. Get Service Details

    kubectl get services hello-minikube
   

   This command retrieves the details of the hello-minikube service.

4. Access the Service

    minikube service hello-minikube
   

   Alternatively, you can use port forwarding to access the service:

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

   This command forwards the local port 7080 to port 8080 of the service.

Expected Output

on , http://localhost:7080
