NEW QUESTION # 37
You have a Deployment named 'web-app-deployment' that uses a service named 'web-app- service' to expose the web application on port 80. You want to update the Deployment to use a new image named 'web-app:v2.0' and update the service to expose a new port, 8080. How would you perform this update using Kubernetes commands?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment:
- Update the Deployment YAML to use the new image 'web-app:v2.0'.
- Use 'kubectl apply -f web-app-deployment.yaml' to apply the updated Deployment.
- Example YAML:
2. Update the Service: - Update the Service YAML to expose the new port 8080. - Use 'kubectl apply -f web-app-service.yaml' to apply the updated Service. - Example YAML:
3. Verify the Update: - Use 'kubectl get deployments web-app-deployment' to verify that the Deployment has updated to use the new image. - Use 'kubectl get services web-app-service' to verify that the Service has updated to expose the new port. - You can then access the web application using the new port through your Kubernetes cluster's IP address or through a NodePort if that's your service type. - If you're using Ingress, you'll need to update your Ingress resource as well to match the new port. ,

NEW QUESTION # 39
You have a Deployment running a web application that receives a significant amount of traffic. You need to implement a strategy to scale the Deployment based on the traffic load while ensuring that the application remains available during the scaling process.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Use a Deployment:
- Deploy the web application using a Deployment with the desired number of replicas.
2. Define a Service:
- Create a Service that exposes the application to the outside world.
- Use a 'type: LoadBalancer' to distribute traffic across the pods.
3. Implement Horizontal Pod Autoscaler (HPA):
- Create an HPA that monitors the web application's CPU usage.
- Configure the HPA to scale the Deployment based on the CPU utilization.
4. Test the Autoscaling: - Simulate increased traffic to the web application. - Observe the HPA scaling the Deployment to meet the demand. 5. Monitor the Service: - Monitor the web application's performance and ensure that it remains available and stable during scaling. 6. Adjust HPA Configuration: - Fine-tune the HPA configuration to optimize scaling based on specific performance needs.
NEW QUESTION # 40
You are running a Deployment named 'web-app' with 3 replicas of a web application container. The container image is hosted in a private registry accessible via a secret named 'my-registry-secret'. You need to implement a rolling update strategy that allows for a maximum of one pod to be unavailable at any given time during the update process. Additionally, you need to configure a 'pre-stop' hook for the container that gracefully shuts down the web application before it is terminated.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment YAML:
- Update the 'replicas' to 3.
- Define 'maxUnavailable: 1' and 'maxSurge: 0' in the 'strategy.rollingUpdate' section to control the rolling update process.
- Configure a 'strategy.type' to 'RollingUpdate' to trigger a rolling update when the deployment is updated.
- Add a Always' to ensure that the new image is pulled
even if it exists in the pod's local cache.
- Add a hook to define a script that gracefully shuts down
the web application before the pod is terminated.
2. Create the Deployment: - Apply the updated YAML file using 'kubectl apply -f web-app.yamP 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments web-app' to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'my-private-registry/web-app:latest' private registry. 5. Monitor the Deployment: - Use "kubectl get pods -l app=web-app' to monitor the pod updates during the rolling update process. You will observe that one pod is terminated at a time, while one new pod with the updated image is created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment web-app' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
