Linux Foundation Certified Kubernetes Application Developer Exam 認定 CKAD 試験問題 (Q233-Q238):

質問 # 233
You have a Deployment named 'wordpress-deployment' that runs 3 replicas of a Wordpress container with the image 'wordpress:latest You need to ensure that wnen a new image is pusned to the Docker Hub repository 'my-wordpress-repo/wordpressaatest' , tne Deployment automatically updates to use the new image. Additionally, you need to set up a rolling update strategy where only one pod is updated at a time- The maximum number of unavailable pods at any given time should be 1.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment YAML.
- Add 'imagePuIIPoIicy: Always' to the container definition to ensure the deployment pulls the latest image from the Docker Hub repository even if a local copy exists.
- Set 'strategy-type: Rollingupdate' to enable a rolling update strategy.
- Configure 'strategy.rollingupdate.maxonavailable: I ' to allow only one pod to be unavailable during the update process.
- Set 'strategy-rollingUpdate.maxSurge: O' to restrict the number of pods added during the update to zero.


質問 # 234
You nave a microservice tnat iS constantly updated With new features and bug fixes. You want to deploy new versions of this service in a way that minimizes downtime and avoids disrupting the existing application. Explain how you can use Kubernetes features to achieve this goal.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Use a Deployment:
- Create a 'Deployment' object to manage your microservice.
- Specify the desired number of replicas and the container image.
- Use a 'rollinglJpdate' strategy to control the update process.

2. Control Rollout Pace: - Use the maxSurge' and 'maxlJnavailable' parameters to control the number of pods that can be unavailable or created during the update process. - For example, 'maxi-Inavailable: ensures that no pods are unavailable during tne update, while 'maxSurge: 1' allows for one extra pod to be created during the update. 3. Trigger Automatic Updates: - Use a 'Deployment's 'spec-template-spec-imagePullPolicy' to trigger updates automatically when a new image is available. - Set imagePullPolicy: Always' to force a pull of the image each time the deployment is updated. 4. Monitor Rollout Progress: - Use kubectl get pods -l app=my-microservice' to monitor the rollout progress. - You can also use tne 'kubectl rollout status deployment/my-microservice' command to get detailed information about the rollout. 5. Use Liveness and Readiness Probes: - Define liveness and readiness probes to ensure that containers are healthy and ready to serve traffic. - The 'Deployment' will automatically restart unhealthy containers, while readiness probes will ensure that new pods are only considered ready for traffic once they are healtny. 6. Traffic Routing: - Use a 'Service' to expose your 'Deployment' to external clients. - Configure the 'Service' to use a 'LoadBalancer' or 'NodePort' to make the service accessible from outside the cluster. Note: This approach ensures a smooth rollout with minimal downtime. New pods are created with the new image, and traffic is gradually shifted to the updated pods while the old pods are gracefully terminated. The liveness and readiness probes ensure that only healthy pods receive traffic, and the automatic updates triggered by 'imagePullPolicy: Always' keep the service up-to-date.


質問 # 235
You are deploying a web application that uses a separate database pod. The database pod is managed by a StatefulSet, and the web application pods need to access the database using tne database pod'S nostname. Explain how you can configure the web application pods to access the database pod using the hostname provided by the StatefulSet.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Configure the StatefulSet:
- Define the database pod within a StatefulSet.
- Ensure that the StatefulSet assigns a unique hostname to each pod, making it accessible by name-
- Example:

2. Configure the Deployment: - Denne the web application pod Within a Deployment. - Use the 'hostAliaseS field in the Deployment's 'spec.template.spec.containers' to map the database pod's hostname to its IP address. - Example:

3. Access Database by Hostname: - Within tne web application's code, you can now access the database using the hostname "database-service" without needing to know the database pod's actual IP address. - Kubernetes will automatically resolve the hostname to the correct IP address based on the hostAliases configuration. 4. Deploy and Test: - Deploy the StatefulSet and Deployment. - Test the web application to ensure that it can connect to the database using the provided hostname. 5. Important - The ' hostAliases' approach is typically used for cases where the database pod's hostname is consistent and predictable. - It might not be suitable for scenarios involving dynamic pod scaling or where the database pod's hostname changes frequently. - In those scenarios, consider using a Service and Service discovery mechanism to connect to the database.


質問 # 236
You are building a microservice application that consists of three components: a frontend service, a backend service, and a database service_ Each service is deployed as a separate pod in a Kubernetes cluster_ You need to implement health checks for each service to ensure that the application remains healthy and available. The frontend service should be able to reach both the backend service and the database service successfully. How would you implement health checks using Kustomize and ensure that the trontend service can only access the backend service and the database service within the cluster?

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Service Resources: Create separate Kubernetes Service resources for each component (frontend, backend, and database) using Kustomize.

2. Implement Health Checks: Add liveness and readiness probes to the containers in each pod's deployment configuration. This will ensure that the pods are continuously monitored for their health.

3. Configure Network Policy: Create a Network Policy to restrict communication between pods. This policy will allow the frontend service to communicate With the backend service and the database service, but prevent it from accessing other pods in the cluster.

4. Apply Configurations: Apply the Kustomize configurations using 'kuactl apply -k .s. This Will create the services, deployments, and network policy in your Kubernetes cluster. 5. Test Health Checks: Verify the health checks are working correctly by checking the pod status and using 'kubectl exec -it' to interact With the pods. You can also use tools like 'kubectl describe deployment' to see tne results of the probes. - If the health checks are not working, troubleshoot the issues by Checking logs, inspecting pod events, and ensuring the probes are configured correctly in the deployments. - You can also use 'kubectl logs to check for any error messages related to network connectivity or the health checks. - If you are experiencing network policy issues, ensure that the policy is correctly applied, and that there are no conflicts with other policies. 6. Monitor Application Health: use Kubernetes monitoring tools to track the health of your microservices and ensure that any issues are detected and resolved promptly. Tools like Prometheus and Grafana can be used to monitor the liveness and readiness probes, as well as other metrics related to your application's health. - Health Checks: The liveness and readiness probes in the deployments allow Kubernetes to continuously monitor the health of the pods- If a probe fails, Kubernetes Will restan the pod or mark it as unhealthy, preventing traffic from being routed to tne pod. - Network Policy: The Network Policy restricts communication between pods. In this example, it ensures that the frontend service can only communicate with the backend service and the database service. - Kustomize: Kustomize helps to simplify tne management of Kubernetes configurations. You can define common configurations and override them for specific deployments or environments using Kustomize. Note: Make sure to adapt the port numbers and labels in the configurations to match your application's setup. You may also need to adjust the initial delay, period, timeout, and failure thresholds for the probes based on the requirements ot your services. ,
