Problem Statement: Deployment of a Reddit-Clone Application🌐

- Do Deployment of the Redit Clone app

- Write an ingress controller for the same to give a custom route

💡Task 1: Deploy a Reddit Clone App

For the second challenge, you'll dive into the world of web applications by deploying a Reddit Clone app. This is an excellent opportunity to apply your Kubernetes knowledge to real-world scenarios.

You'll need to:

• Create Kubernetes resources (deployments, services, etc.) for the Reddit Clone application.

• Ensure that the app is up and running on your cluster.

🔹 Step 1: Install minikube on AWS EC2 instance

Follow the below blog for minikube installation: https://ayushi1503.hashnode.dev/getting-started-installing-minikube-and-creating-your-first-kubernetes-pod

🔹 Step 2: Cloning the repository of the project

Inside the projects directory clone the GitHub repository:

https://github.com/Vasishtha15/reddit-clone-k8s-ingress.git

git clone https://github.com/Vasishtha15/reddit-clone-k8s-ingress.git

🔹Step 3: Navigate to project directory and create a namespace named reddit

🔹Step 4: Apply the deployment file

deployment.yml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: reddit-clone-deployment
  namespace: reddit
  labels:
    app: reddit-clone
spec:
  replicas: 2
  selector:
    matchLabels:
      app: reddit-clone
  template:
    metadata:
      namespace: reddit
      labels:
        app: reddit-clone
    spec:
      containers:
      - name: reddit-clone
        image: rohanrustagi18/redditclone
        ports:
        - containerPort: 3000

kubectl apply -f deployment.yml

Deployment is created.

Now, Verify the the deployment-

Verify the pod status-

🔹Step 5: Apply the service file and verify it.

service.yml:

apiVersion: v1
# Indicates this as a service
kind: Service
metadata:
  # Service name
  name: reddit-clone-service
  namespace: reddit
spec:
  selector:
    # Selector for Pods
    app: reddit-clone
  ports:
    # Port Map
  - port: 3000
    targetPort: 3000
    protocol: TCP
  type: LoadBalancer

kubectl apply -f service.yml

💡Task 2: Write an Ingress Controller

To make the Reddit Clone accessible from the outside world, you'll need to configure an ingress controller. This allows you to provide a custom route to your application.

You'll need to:

• Set up an ingress controller.

• Define rules and routes to access your Reddit Clone app.

• Test the custom routes to ensure they work as expected.

ingress.yml:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-reddit-app
  namespace: reddit
spec:
  rules:
  - host: "domain.com"
    http:
      paths:
      - pathType: Prefix
        path: "/test"
        backend:
          service:
            name: reddit-clone-service
            port:
              number: 3000
  - host: "*.domain.com"
    http:
      paths:
      - pathType: Prefix
        path: "/test"
        backend:
          service:
            name: reddit-clone-service
            port:
              number: 3000

🔹 Step 1: Apply the ingress file and verify it.

kubectl apply -f ingress.yml

🔹 Step 2:Exposing the deployment:

kubectl expose deployment reddit-clone-deployment -n reddit --type=NodePort

🔹 Step 3:Exposing the service:

kubectl port-forward svc/reddit-clone-service -n reddit 3000:3000 --address 0.0.0.0

🔹 Step 4: Add port 3000 to the security group of your instance.

🔹 Step 5: Test the Application

Go to your browser and access the application at ec2_ip:3000:

🌟Conclusion:

In this problem statement, we have further expanded our Kubernetes prowess. We orchestrated the deployment of a multi-component application, comprising frontend, backend, and database services. To enhance accessibility and user experience, we ventured into the realm of Ingress controllers. Crafting custom routes and directing traffic with precision, we optimized the accessibility of our Reddit Clone application.

Thank you for joining me on this Kubernetes expedition. Stay tuned for more exciting challenges and discoveries in the world of DevOps. 🚀
