k8s-demo-app

This repository contains instructions and configuration files for deploying a Kubernetes cluster using MongoDB and a Docker container.

The Original Tutorial

Kubernetes Crash Course for Absolute Beginners

Prerequisites

Before deploying the Kubernetes cluster, you will need to have the following software installed:

• Kubernetes.
• Docker.
• kubectl.

You will also need to have an active Kubernetes cluster to deploy the application to.

Getting Started

To get started,clone this repository to your local machine using the following command:

git clone https://github.com/Tareq-Assiri/k8s-demo-app

pull the k8s-demo-app image to your local machine using the following command:

docker pull nanajanashia/k8s-demo-app:v1.0

Deploying to Kubernetes

To deploy the application to your Kubernetes cluster, navigate to the k8s-demo-app directory and run the following command:

kubectl apply -f mongo-secret.yaml
kubectl apply -f mongo.yaml
kubectl apply -f mongo-config.yaml
kubectl apply -f webapp.yaml

This will create a MongoDB deployment with 3 replicas and a webapp deployment with 5 replicas for the k8s-demo-app container.

Accessing the Application

To access the application, you will need to access the NodePort service for the k8s-demo-app container by navigating to http://<node-ip>:<node-port> in your web browser.

Cleaning Up

To delete the MongoDB and k8s-demo-app deployments, run the following command:

kubectl delete deployment mongo-deployment webapp-deployment

To delete the NodePort service, run the following command:

kubectl delete service webapp-service

this is just an example on how to deploy a Kubernetes cluster using a docker image
