NEW QUESTION # 39
You have a Deployment running a web application with three replicas. The application is exposed using a 'NodePort' service. You need to configure the service so that it allows traffic only from specific IP addresses (e.g., 192.168.1.10, 192.168.1.20).
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a NetworkPolicy:
- Define a NetworkPolicy resource that allows traffic from the specified IP addresses to the Deployment pods.
2. Apply the NetworkPolicy: - Apply the YAML file using 'kubectl apply -f networkpolicy.yaml'. 3. Verify the NetworkPolicy: - Check the status of the NetworkPolicy using 'kubectl get networkpolicies allow-specific-ips -n 4. Test the Access: - Attempt to access the web application from the allowed IP addresses. You should be able to access it. - Try to access the application from other IP addresses. You should not be able to access it. Note: Replace " with the actual namespace where your Deployment and NetworkPolicy are located.
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.
NEW QUESTION # 41
