NEW QUESTION # 71
You need to expose a service with multiple endpoints, each serving a specific path, using a single Ingress resource. Each endpoint is running on a different port, and you want to configure SSL termination for the entire Ingress. How would you achieve this?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Ingress Resource:
- Create an Ingress resource with the desired host and paths for each endpoint.
- Example:
- This configuration defines the host "example.com" and two paths: "/api" routed to "api-service" on port 8080 and "[blog" routed to "blog-service" on port 8081. 2. Create the TLS Secret: - Create a Secret containing your SSL certificate and private key for the domain "example.com". - Example:
- Replace " and with the actual content of your SSL certificate and private key. 3. Deploy the Services: - Ensure that the services "api-service" and "blog-service" are deployed and accessible on their respective ports (8080 and 8081 4. Apply the Ingress Configuration: - Apply the Ingress configuration using 'kubectl apply -f multiple-endpoints-ingress.yamP. 5. Verify the Ingress: - Access the Ingress using the defined host "example.com". - Check that requests to "/api" are routed to the "api-service" and requests to "[blog" are routed to the "blog- service", with SSL termination working as expected.

NEW QUESTION # 73
You are running a stateful application on Kubernetes with a Deployment that manages five pods. Each pod has a persistent volume claim (PVC) that mounts a volume to store application dat a. You need to ensure that the pods are always deployed in the same order and that data is consistently accessed from the same PVC. How can you achieve this using Kubernetes features?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Enable StatefulSet: Create a StatefulSet instead of a Deployment. StatefulSets are specifically designed to manage stateful applications.
2. Use the 'podManagementPolicy' Field: Set the 'podManagementPolicy' field to 'OrderedReady' in the spec' section of your StatefulSet to ensure that pods are deployed in the same order and become ready before new pods are deployed. This policy guarantees that the previous pod is ready before the next one is started.
3. Utilize Persistent Volumes: Ensure that your PVCs are bound to persistent volumes (PVs). PVs are the underlying storage resources that back your PVCs. They are usually provisioned using a storage class.
4. Set 'serviceName': The 'serviceName' field should be specified in the StatefulSet to create a service for accessing the application. This service allows you to access the application based on its name, regardless of which pod is currently serving the requests.
5. Verify Deployment: After applying the YAML, check the status of your StatefulSet using 'kubectl get statefulset my-stateful-app'. Ensure that the pods are deployed in the specified order and are running. You can also verify the PVCs using 'kubectl get pvc' to make sure they are bound to the correct PVs.
