PROJECT - πŸš€ Deploying Reddit Clone Web App on Kubernetes Cluster: A Step-by-Step Guide

πŸ“ Introduction:

Container orchestration with Kubernetes has become a standard for deploying and managing applications efficiently. In this detailed guide, we will walk you through the process of deploying a Reddit clone web application onto a Kubernetes cluster hosted on AWS. By following these steps, you will not only learn the deployment process but also gain insights into the power of Kubernetes for managing containerized applications.

Step 1: Provision AWS Instances 🌐

Begin by accessing the AWS console and creating two instances with specific configurations:

  • Deployment Server:

    • AMI: Ubuntu

    • Type: t2.medium

Ensure that you name these instances accordingly for easy reference.

Step 2: Clone the CodeπŸ“‚

πŸ“¦ On the machine, clone the codebase of your Reddit clone web application.


Step 3: Prerequisites πŸ› οΈ

On Deployment Server:

  • Update the server: sudo apt-get update

  • Install Docker: sudo apt-get install -y

  • Give permission to Docker: sudo usermod -aG docker $USER && newgrp docker

  • Install Minikube and Kubectl:

      curl -LO
      sudo install minikube-linux-amd64 /usr/local/bin/minikube
      sudo snap install kubectl β€” classic
      minikube start β€” driver=docker

Step 4: Write a Dockerfile for the Project 🐳

Create a Dockerfile for your Reddit clone project with the following content:

FROM node:19-alpine3.15

WORKDIR /reddit-clone

COPY . /reddit-clone

RUN npm install


CMD [β€œnpm”,”run”,”dev”]

Step 5: Build and Push Docker Image πŸš€

Build the Docker image from the Dockerfile using the following command:

docker build . -t sumanprasad007/reddit-clone

After building the image, push it to Docker Hub by running:

docker login
# Enter your username and password
docker push sumanprasad007/reddit-clone

Step 6: Connect to Deployment Server πŸ–₯️

SSH into the Deployment Server.

Step 7: Install Minikube and Kubectl

Ensure Minikube and Kubectl are installed on the Deployment Server.

Step 8: Deploy Docker Image 🚒

Now, it's time to deploy the Docker image from Docker Hub onto your Kubernetes cluster.

Step 9: Create a Kubernetes Folder πŸ“

Create a folder named "K8s" on the Deployment Server.

Step 10: Create a Deployment YAML File πŸ“

Inside the "K8s" folder, create a file named "Deployment.yml" and add the following content:

apiVersion: apps/v1
kind: Deployment
  name: reddit-clone-deployment
    app: reddit-clone
  replicas: 2
      app: reddit-clone
        app: reddit-clone
        - name: reddit-clone
          image: trainwithshubham/reddit-clone
            - containerPort: 3000

Step 11: Apply the Deployment File πŸ“œ

Apply the Deployment file to create pods:

kubectl apply -f Deployment.yml

Step 12: Verify Deployments 🧐

To ensure that the deployments are successful, use the following command:

kubectl get deployments

Step 13: Create a Kubernetes Service 🌐

Now, you need to create a Service to provide an IP address for your application within the cluster.

Step 14: Create a Service YAML File πŸ“

Inside the "K8s" folder, create a file named "Service.yml" and add the following content:

apiVersion: v1
kind: Service
  name: reddit-clone-service
    app: reddit-clone
  type: NodePort
    - port: 3000
      targetPort: 3000
      nodePort: 31000
    app: reddit-clone

Step 15: Apply the Service File πŸ“œ

Apply the Service file to create a service:

kubectl apply -f Service.yml

Step 16: Check the Service 🌐

To verify that the service is created successfully, run:

kubectl get services

Step 17: Access the Application πŸš€

You can now access your application by visiting the URL provided by Minikube:

minikube service reddit-clone-service β€” url

Step 18: Expose the Application to the Internet 🌍

To make your application accessible from the internet, you'll need to configure port forwarding.

Step 19: Port Forwarding πŸ”„

Run the following command for port forwarding:

kubectl port-forward svc/reddit-clone-service 3000:3000

Step 20: Access Your Live Reddit Clone 🌐

Visit your Reddit Clone web app at the provided domain or IP address, and it should now be accessible to the world.
