NEW QUESTION # 88
You have a Kubernetes application that uses a Deployment named sweb-app' to deploy multiple replicas of a web server pod. This web server application needs to be accessible through a public IP address. You are tasked with implementing a service that allows users to access the application from outside the cluster. However, the service should exposed via a specific port number (8080), regardless ot the port that the web server listens on inside the pods.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create the Service YAMI-:
- Define the service type as 'LoadBalancer' to expose it via a public IP
- Set the 'targetPort' to the port that the web server listens on inside the pods (let's assume it's 8080)-
- Set the 'port' to 8080, which will be the port used to access the service from outside the cluster.

2. Apply the Service: - Use 'kubectl apply -f web-app-service.yaml' to create the service- 3. Get the External IP: - Once the service iS created, use 'kubectl get services web-app-services to get the external IP address. This will be assigned by the cloud provider and will be available for users to access the application. 4. Test the Service: - Access the application using the external IP address and port 8080. For example, if the external IP is '123.45.67.89' , you would access the application through 'http://123.45.67.89:8080' ,

- Add a 'spec-template.spec.imagePullPolicy: Always' to ensure that the new image is pulled even if it exists in the pod's local cache.

2. Create the Deployment - Apply the updated YAML file using 'kubectl apply -f ecommerce-app-deployment.yaml' 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments ecommerce-app-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'example/ecommerce-app:latest' Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=ecommerce-apps to monitor the pod updates during the rolling update process. You will observe that two pods are terminated at a time, while three new pods with the updated image are created. 6.
