Linux Foundation Certified Kubernetes Application Developer Exam 認定 CKAD 試験問題 (Q166-Q171):

質問 # 166
You are running a Kubernetes cluster that manages a critical web application. Your application uses a custom resource called 'Database' to represent database instances. You want to ensure that only authorized users within your organization can create and manage these database instances. How would you implement this using ServiceAccounts and Role-Based Access Control (RBAC)?

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ServiceAccount:
- Create a ServiceAccount specifically for managing database instances. This ServiceAccount will be assigned to the users authorized to work with databases.

- Apply the ServiceAccount to your cluster using 'kubectl apply -f serviceAccount.yamI' 2. Create a Role: - Define a Role to specify the permissions that the 'database-manager' ServiceAccount should have. This Role will allow the ServiceAccount to create, update, delete, and list 'Database custom resources.

- Apply the Role using 'kubectl apply -f role.yamr 3. Bind the Role to the ServiceAccount - Use a RoleBinding to link the 'database-managers ServiceAccount to the 'database-manager-roles

- Apply the RoleBinding using 'kubectl apply -f roleBinding.yaml' 4. Use the ServiceAccount: - When users need to manage database instances, they should authenticate to the Kubernetes cluster using credentials associated with the 'database-manager ServiceAccount This will grant them the permissions defined in the Role. - Example: - 'kubectl create database my-database Important Notes: - Replace "'your-group"' and '"your-namespace"' with the actual values for your custom resource and namespace, respectively. - You might need to create a ClusterRole instead of a Role if you want the permissions to apply across all namespaces in your cluster. - This example assumes you've already defined the CustomResourceDefinition (CRD) for the 'Database' resource.]

質問 # 167
You are building a microservice called 'order-service' that handles order processing. You need to configure a Securitycontext for the 'order-service' container tnat ensures it can access the network to communicate With other services and access specific hostPath volumes, but it should not have root privileges.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Securitycontext:
- Create a 'securityContext' section within the 'spec.template.spec.containers' block for your 'order-service' container.
- Set 'runAslJser' to a non-root IJID (e.g., 1001) to prevent running as the root user-
- Set 'allowPrivilegeEscalation' to 'false' to prevent the container from escalating its privileges.
- Set 'capabilities' to an empty array (so') to disable any additional capabilities.

2. Mount HostPath Volumes: - Define 'volumeMountS for the required hostPath volumes. - Specify the mount path within the container C Idata' and 'Iconfig' in this example) and the volume name. - Define corresponding 'volumes with the 'hostPath' type, specifying the source path on the host and the volume name. 3. Create the Deployment: - Apply the Deployment YAML file using 'kubectl apply -f order-service-deployment-yaml' - The 'securitycontext' restricts the container's access to the host system's resources and prevents privilege escalation. - Setting 'runAsUserS to a non-root I-IID ensures that tne container runs as a non-root user - 'allowPriviIegeEscalation' prevents the container from elevating its privileges, even if it has the necessary capabilities. - The 'capabilities' section allows you to explicitly detine WhiCh capabilities the container snould nave. In this case, an empty array disables all additional capabilities, restricting the container's potential actions. - The 'volumeMounts' define how hostPath volumes are mounted within the container, providing access to specific directories on the host system. This configuration ensures that the 'order-service' container can access specific hostPath volumes and the network for communication with other services without running as root and without any additional capabilities, enhancing security.

Task
Create a new deployment for running.nginx with the following parameters;
* Run the deployment in the kdpd00201 namespace. The namespace has already been created
* Name the deployment frontend and configure with 4 replicas
* Configure the pod with a container image of lfccncf/nginx:1.13.7
* Set an environment variable of NGINX__PORT=8080 and also expose that port for the container above See the solution below.

質問 # 169
You are working on a Kubernetes application that requires ephemeral storage. The application data needs to be stored within the pod's container and should be deleted when the pod is deleted. How can you achieve this using ephemeral storage in Kubernetes?

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Deployment with an EmptyDir Volume:
- Define an 'EmptyDirs volume in tne Deployment YAML.
- Specify the volume mount path Within the container.
- Example:

2. Create the Deployment: - Apply the Deployment YAML using 'kubectl apply -f my-app-deployment-yamr 3. Verify the Deployment - Check the status of the Deployment using ' kubectl get deployments my-app' - Verify that the Pod is running and using the EmptyDir volume. 4. Test Ephemeral Storage Behavior: - Write data to the Aldata' directory within the container - Delete the pod. - Create a new pod from the same Deployment. - The data written to tne "data' directory will no longer be present in the new pod, as the volume is ephemeral and is deleted when the pod is deleted.

質問 # 170
You have a Kubernetes Job that runs a Python script for data processing. The script takes 30 minutes to complete, and you need to ensure that the Job is retried up to 3 times if it fails. Additionally, you want the Job to complete within a maximum of 45 minutes. Create a Job YAML file with appropriate configuration.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Job YAML file:

2. Apply the Job YAML file: bash kubectl apply -f data-processing-job.yaml 3. Monitor the Job: bash kubectl get jobs -w This will show the status of the Job, including its completion status and retries, if any. 4. Examine the Job's Pods: bash kubectl get pods -l job-name-data-processing-job You can use the 'kubectl logs command to cneck tne logs of tne POdS created by tne Job to investigate any potential failures. - 'backoffLimit: 3': This specifies that the Job can be retried up to 3 times in case of failures. - 'activeDeadlineSeconds: 2700': This sets the maximum duration for the Job to run (2700 seconds, which is equal to 45 minutes). If the Job exceeds this time limit, it will be automatically terminated. - 'restartPolicy: Never: This ensures that Pods created by the Job will not be restarted automatically. - 'command: ["python", "data_processing_script.py'T: This defines the command to execute inside the container. - 'resources-requests': This defines the minimum resource requirements for the container, including CPU and memory. - 'resources-limits: This can be used to define maximum resource limits for the container. This setup will attempt to run the data processing script If it fails, it will be retried up to 3 times, with an increasing delay between each retry. The Job will be terminated after 45 minutes if it does not complete successfully.,
