Project: Deployment Of Redit Clone application using Kubernetes with Ingress and expose it to the world using Minikube as the cluster.

Required tools for this project-:

• Docker

• Minikube cluster ( Running )

• kubectl

• Git

  steps to execute this project-:

  Step 1: Clone this repository to your local machine: git clone https://github.com/LondheShubham153/reddit-clone-k8s-ingress.git

  Step 2: Navigate to the project directory: cd reddit-clone-k8s-ingress

  Step 3: Create a Dockerfile for redit-app.

    FROM node:19-alpine3.15
  
    WORKDIR /reddit-clone
  
    COPY . /reddit-clone
    RUN npm install
  
    EXPOSE 3000
    CMD ["npm","run","dev"]
  

  Step 4: Build the Docker image for the Reddit clone app: docker build -t reddit-clone-app

  

  

  Step 5: Push the docker container to the docker hub. Command to push the docker image is:

    login to dockerhub in local:
    docker login
    push the container to dockerhub:
    docker push achyut197/redit-clone:latest
  

  

  Step 6: Deploy the app to Kubernetes: kubectl apply -f deployment.yaml . 6

  deployment.yaml:

    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: reddit-clone-deployment
      labels:
        app: reddit-clone
    spec:
      replicas: 2
      selector:
        matchLabels:
          app: reddit-clone
      template:
        metadata:
          labels:
            app: reddit-clone
        spec:
          containers:
          - name: reddit-clone
            image: achyut197/redit-clone
            ports:
            - containerPort: 3000
  

  Step 7: Access this app outside the cluster by creating a service.yaml .apply the service.yaml file by using kubectl command.

    # service.yaml-:
    apiVersion: v1
    kind: Service
    metadata:
      name: reddit-clone-service
      labels:
        app: reddit-clone
    spec:
      type: NodePort
      ports:
      - port: 3000
        targetPort: 3000
        nodePort: 31000
      selector:
        app: reddit-clone
  

•     kubectl apply -f service.yaml
  

  

  Step 8: create URL link for redit app to access:

•     minikube service redit-clone-service --url
      curl -L http://192.168.49.2:31000
  

  

  redit-clone app was deployed.

  Step 9: Enable Ingress by using Command: minikube addons enable ingress

  Step 10: Expose the app as a Kubernetes service: kubectl expose deployment reddit-deployment --type=NodePort --port=500

  Step 11: forward redit-clone service.

  

  

  Step 12: Create an Ingress resource: kubectl apply -f ingress.yaml

  ingress.yaml:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-reddit-app
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 13: Test Ingress by typing this command: curl http://domain.com/test
