NEW QUESTION # 120
You are building a microservice architecture for a new e-commerce application. This architecture consists of three microservices: 'product- service' , 'can-service' , and 'order-service'. Each microservice nas a dedicated database and utilizes a Redis cacne for performance optimization.
You are tasked with designing the 'product-service , which is responsible for managing product information (name, description, price, inventory).
Implement a multi-container Pod design for the product-service' that addresses the following requirements:
- The Pod must include a primary container running the 'product-service' application.
- The Pod must include a secondary container for Redis to cache frequently accessed product data.
- The Pod must use a shared volume to persist the Redis data across container restarts.
- The 'product-service' must connect to the local Redis instance in the Pod for optimized data retrieval.
- The product-service' should be configured to periodically update the Redis cache With the latest product data from the database.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create the Deployment YAML:
- Define a Deployment with the name 'product-service'
- Set the replicas to ' 2' to provide redundancy and high availability.
- Specify the labels Sapp: product-service' for selecting the Pods in the Deployment.
- Create a 'template' section to define the Pod specification.
2. Create the Persistent Volume Claim (PVC): - Define a PVC with the name 'redis-pvc' - Specify the storage class and access mode. - Set the required storage size for Redis data.
3. Deploy the Resources: - Apply the Deployment and PVC using 'kubectl apply -f deployment.yamr and 'kubectl apply -f pvc.yamr. 4. Verify the Deployment: - Check the status of the Deployment using 'kubectl get deployments product-service' and ensure that two Pods are running. - Check the status of the PVC using 'kubectl get pvc redis-pve 5. Configure the 'product-service'- - Modify the 'product-service' application to use the Redis instance in the Pod as the cache backend. - Configure the -product-service' to periodically tetch data trom the database and update the Redis cache. 6. Test the Application: - Send requests to the 'product-service to retrieve product data. - Monitor the Redis cache to ensure that it's being used and updated as expected. Important Considerations: - Ensure that the 'product-service' application is properly configured to connect to the Redis instance within the same Pod. - Use a suitable Redis cache library or framework in the 'product-service for efficient caching. - Implement a proper caching strategy (e.g., TTL, cache eviction) to prevent stale data. - Monitor the Redis cache performance and resource usage to optimize the cache configuration.
NEW QUESTION # 121
You must connect to the correct host . Failure to do so may result in a zero score.
[candidate@base] $ ssh ckad00034c
Task
A Deployment named content-marlin-deployment , running in namespace content-marlin is exposed via Ingress content-marlin-ingress .
The manifest files for the Deployment, Service and Ingress can be found at /home/candidate/content-marlin/.
The Deployment is supposed to be reachable at
http://content-marlin.local/content-marlin , but requesting this URL is currently returning an error.
Answer:
Explanation:
See the Explanation below for complete solution.
Explanation:
ssh ckad00034c
You're debugging an Ingress # Service # Deployment chain. The fastest way is:
* reproduce the error with the right Host header
* check Ingress rules (host/path/backend)
* check Service (selector/port/targetPort)
* check Endpoints (do we have ready pods?)
* fix the manifest(s) under /home/candidate/content-marlin/
* apply + re-test
Below are the exact commands + the most common fixes for this exact symptom.
1) Reproduce the failing request correctly
Even if DNS isn't set up, you can test with a Host header:
curl -i -H "Host: content-marlin.local"
http://127.0.0.1/content-marlin
If your ingress controller is not on localhost, find the NodePort/LoadBalancer IP. In these labs it's often localhost via a local proxy, but if needed:
kubectl get svc -A | egrep -i 'ingress|nginx'
kubectl get nodes -o wide
(But start with the localhost curl above.)
2) Inspect the provided manifests (this is what you must edit)
cd /home/candidate/content-marlin/
ls -l
sed -n '1,200p' *.yaml
Also view what's currently live in the cluster:
kubectl -n content-marlin get deploy,svc,ingress
kubectl -n content-marlin describe ingress content-marlin-ingress
kubectl -n content-marlin get ingress content-marlin-ingress -o yaml
What to look for in the Ingress:
* spec.rules.host should be content-marlin.local
* spec.rules.http.paths[].path should match /content-marlin
* Backend service name must be your service
* Backend service port must match the service port (name or number)
* pathType should be Prefix (usually safest)
3) Validate Service # Pod wiring (most common real cause)
3.1 Check service selector and ports
kubectl -n content-marlin get svc -o wide
kubectl -n content-marlin describe svc content-marlin-deployment 2>/dev/null || true kubectl -n content-marlin describe svc Identify the service that the Ingress points to (from describe ingress).
Check if the Service selector matches pod labels:
kubectl -n content-marlin get pods --show-labels
kubectl -n content-marlin get svc <SERVICE_NAME> -o jsonpath='{.spec.selector}{"\n"}'
3.2 Check endpoints (this tells you instantly if traffic can reach pods) kubectl -n content-marlin get endpoints kubectl -n content-marlin get endpoints <SERVICE_NAME> -o wide
* If ENDPOINTS is empty # Service selector doesn't match Pods OR Pods aren't Ready.
3.3 If endpoints empty, check pod readiness and labels
kubectl -n content-marlin get pods -o wide
kubectl -n content-marlin describe pod <pod-name>
4) Apply the most likely fix patterns
Fix pattern A: Ingress path needs rewrite
If your app serves / but you route /content-marlin, you often need rewrite.
Edit content-marlin-ingress manifest (in /home/candidate/content-marlin/) to include:
* path: /content-marlin
* pathType: Prefix
* annotation: rewrite to / (common for nginx ingress)
Example (typical nginx-ingress):
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- host: content-marlin.local
http:
paths:
- path: /content-marlin
pathType: Prefix
backend:
service:
name: <SERVICE_NAME>
port:
number: 80
If your ingress controller is not nginx, rewrite annotation may differ. But in CKAD labs, it's very often nginx.
Fix pattern B: Ingress points to wrong Service port
If the Ingress backend says port 80 but your Service exposes 8080 (or uses a named port), align them:
* Either change Ingress backend port.number
* Or change Service spec.ports[].port / targetPort
Fix pattern C: Service selector mismatch (endpoints empty)
If pods have label app=content-marlin but service selector is app=content-marlin-deployment (or vice versa), fix the Service selector to match pod labels.
Service should have:
spec:
selector:
app: <label-that-actually-exists-on-pods>
Fix pattern D: Service targetPort wrong
If container listens on 8080 but service targetPort is 80, fix it:
spec:
ports:
- port: 80
targetPort: 8080
5) Apply the corrected manifests
After editing the YAMLs under /home/candidate/content-marlin/:
kubectl apply -f /home/candidate/content-marlin/
Wait for readiness:
kubectl -n content-marlin rollout status deploy content-marlin-deployment kubectl -n content-marlin get endpoints kubectl -n content-marlin describe ingress content-marlin-ingress
6) Re-test the URL
curl -i -H "Host: content-marlin.local"
http://127.0.0.1/content-marlin
If you still get errors, also check ingress controller logs/events quickly:
kubectl -n content-marlin get events --sort-by=.lastTimestamp | tail -n 30 kubectl get pods -A | egrep -i 'ingress|nginx' The fastest way for you to finish in 1 shot Run these and paste the output (I'll tell you exactly which line to change and what to change it to):
kubectl -n content-marlin describe ingress content-marlin-ingress
kubectl -n content-marlin get svc -o wide
kubectl -n content-marlin get endpoints -o wide
kubectl -n content-marlin get pods --show-labels
sed -n '1,200p' /home/candidate/content-marlin/*.yaml
But even without pasting, if you follow steps 2-4 above, you'll find the broken link (Ingress rule, Service port, selector, or rewrite) and fix it cleanly.

You can adjust the code and logic according to your specific requirements. ,
NEW QUESTION # 123
You have a Deployment named 'wordpress-deployment' that runs 3 replicas of a WordPress container. You want to implement a blue- green deployment strategy for this deployment This strategy should involve creating a new replica set with the updated image, and then gradually shitting traffic to the new replica set. After the traffic has been shifted, the old replica set should be deleted. This process should be fully automated whenever a new image is pushed to the Docker Hub repository 'example/wordpress:latest'
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Kubernetes Secret for Docker Hub Credentials:
- You'll need a Secret to securely store your Docker Hub credentials for pulling images. Create a Secret with the following YAML:
- Replace with the base64 encoded content of your Docker Hub credentials file. This file is typically named '~/.docker/config.json' and contains your Docker Hub username and password. You can create this file or update it manually. To encode the file, use a command like 'base64 ~/.docker/config .jsons 2. Create a ConfigMap for Deployment Configuratiom - Create a ConfigMap to hold the image name and any other deployment-specific configuration:
3. Define a Deployment with a Blue-Green Strategy: - Create a Deployment named swordpress-deployment that incorporates the blue-green deployment strategy. This Deployment will have a 'strategy' section with a 'type' of 'Recreate' (for initial deployment) and a 'blueGreenDeploymentStrategy' section: 4. Create a Service.
- Create a Kubernetes Service that exposes your WordPress application. This service will automatically route traffic to the active replica set.
5. Automate the Blue-Green Deployment - Use a 'DeploymentConfig' resource to configure the automatic deployment
6. Apply the resources: - Apply all the YAML files using 'kubectl apply -f' to create the necessary resources. 7. Trigger the Blue-Green Deployment - Push a new image to the Docker Hub repository 'example/wordpress:latest' The 'Deploymentconfig' will automatically trigger the blue-green deployment: -A new replica set with the updated image will be created, and traffic will be shifted to the new replica set gradually - Once the traffic has been shifted, the old replica set will be deleted. Note: This implementation assumes that you are using OpenShift. If you are using a different Kubernetes distribution, the configuration may need to be adjusted SligntlY. ,
NEW QUESTION # 124
You have a Kubernetes deployment tnat uses a ConfigMap to provide configuration settings to your application. You need to update tne ConfigMap with new settings without restarting the deployment.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the ConfigMap:
- Create or update your ConfigMap YAML file, for example, Sapp-config.yaml':
- Replace and 'debug' with the desired new values. 2. Apply the Updated ConfigMap: - Apply the updated ConfigMap using: bash kubectl apply -f app-config.yaml 3. Verify the Update: - Check the updated ConfigMap using: bash kubectl get configmap app-config -o yaml - Confirm that the new settings are reflected in the ConfigMap. 4. (Optional) Monitor Application Logs: - If your application is logging configuration values, you can check the logs to ensure it's now using the updated settings.
