How to deploy this app?

To deploy your web application using Kubernetes, follow these steps:

1. Create a YAML file for the deployment: Create a file named web-app.yaml with the following content:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: web-app
     namespace: webapp
   spec:
     replicas: 1
     selector:
       matchLabels:
         app: web-app
     template:
       metadata:
         labels:
           app: web-app
       spec:
         containers:
         - name: nginx
           image: nginx:latest
           ports:
           - containerPort: 80

   This configuration creates a deployment named web-app in the webapp namespace, running one replica of the NGINX web server.

2. Apply the deployment: Use the following command to deploy the application to your Kubernetes cluster:

   kubectl apply -f web-app.yaml

3. Verify the deployment: Check that the web application is running in the webapp namespace with the following command:

   kubectl get pods -n webapp

   You should see the web-app pod listed as running.
