Linux Foundation Certified Kubernetes Application Developer Exam 認定 CKAD 試験問題 (Q62-Q67):

質問 # 62
You are tasked with deploying an application with a deployment named 'web-app' that requires a specific SecurityContext to run. The application should be able to access a specific hostPath volume mounted at '/data' and should be able to run as a non-root user with a specific UID. You need to define the Securitycontext in your Deployment configuration to ensure the application runs with the required privileges and access.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Securitycontext in the Deployment YAML:
- Create a 'securityContext' section within the 'spec-template.spec.containerss block for your application container
- Set the 'runAsLJser' field to the desired non-root IJID (e.g., 1000).
- Specify 'allowPrivilegeEscalatiom false' to prevent the container from escalating its privileges beyond the defined CJID.
- Add a 'hostPatm volume mount with 'readOnly: false' to allow the application to read and write to the mounted directory.
- Define a 'volume' with the 'hostPath' type, specifying the source path (e.g., ',/data') and the path within the container where it should be mounted.

2. Create the Deployment: - Apply the Deployment YAML file using 'kubectl apply -f web-app-deployment.yamr 3. Verify the Deployment - Check the status of the Deployment using 'kubectl get deployments web-app'. You should see a running pod with the specified Securitycontext. - Use kubectl describe pod' to inspect the details of the pod and verify that the Securitycontext is applied correctly. 4. Test the Application: - Ensure that your application can access and modify the '/data' volume with the specified user ID (1000). - The 'securitycontext' allows you to define security settings for the application container, such as user ID and privilege escalation- - 'runAsIJsers specifies the IJID under which the container should run. - 'allowPrivilegeEscalation' controls whether the container can elevate its privileges beyond the specified IJID. - 'hostPath' volume mounts allow containers to access directories on the host system. - 'readOnly' determines whether the volume mount iS read-only or read-write. - Ensure your container image has the necessary permissions to access the hostPath volume within the specified UID.

質問 # 63
Refer to Exhibit.

Context
A project that you are working on has a requirement for persistent data to be available.
Task
To facilitate this, perform the following tasks:
* Create a file on node sk8s-node-0 at /opt/KDSP00101/data/index.html with the content Acct=Finance
* Create a PersistentVolume named task-pv-volume using hostPath and allocate 1Gi to it, specifying that the volume is at /opt/KDSP00101/data on the cluster's node. The configuration should specify the access mode of ReadWriteOnce . It should define the StorageClass name exam for the PersistentVolume , which will be used to bind PersistentVolumeClaim requests to this PersistenetVolume.
* Create a PefsissentVolumeClaim named task-pv-claim that requests a volume of at least 100Mi and specifies an access mode of ReadWriteOnce
* Create a pod that uses the PersistentVolmeClaim as a volume with a label app: my-storage-app mounting the resulting volume to a mountPath /usr/share/nginx/html inside the pod

質問 # 64
Context

Task:
1) First update the Deployment cka00017-deployment in the ckad00017 namespace:
To run 2 replicas of the pod
Add the following label on the pod:
Role userUI
2) Next, Create a NodePort Service named cherry in the ckad00017 nmespace exposing the ckad00017-deployment Deployment on TCP port 8888

質問 # 65
You have a Deployment named 'my-app-deployment' that runs 3 replicas of a Spring Boot application. This application needs to access a PostgreSQL database hosted on your Kubernetes cluster. You need to create a Custom Resource Definition (CRD) to define a new resource called 'Database' to represent the PostgreSQL database instances within your cluster. This CRD should include fields for specifying the database name, username, password, and the host where the database is deployed. Further, you need to configure the 'my- app-deployment' to use the 'Database' resource to connect to the PostgreSQL instance dynamically.

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the CRD:
- Create a YAML file named 'database.crd.yaml' to define the "Database' resource:

2. the CRD: - Apply tre 'database.cre.yaml' using 'kubectl "ply -f database.crd.ya'mr 3. Create A Database Instance: - 'eate YAML file 'd:tabaseyarnl' to define a database instance

4. Apply the Database Instance: - Apply the 'database.yaml' using 'kubectl apply -f database.yamr 5. IJpdate the Deployment - Update the Amy-app-deployment.yaml' to use the 'Database' resource:

6. Apply the Updated Deployment: - Apply the updated 'my-app-deployment.yamr using 'kubectl apply -f my-app-deployment.yamr 7. Verify the Configuration: - Use 'kubectl get databases to check the database instance. - Use 'kubectl describe pod -l app=my-app' to verify that the pods are using the values from the 'Database' resource tor connecting to the PostgreSQL database. This approach demonstrates how to utilize CRDs to define custom resources in Kubernetes and how to connect applications dynamically to these resources. The CRO ensures proper definition of the database resource, while the deployment utilizes the 'fieldRef mechanism to access and retrieve database connection details directly from the CRD, enabling dynamic configuration and simplification of application setup.,

質問 # 66
You have a Deployment named 'web-app-deployments that runs a web application in a containerized environment. The application is designed for high availability and scalability, but you need to ensure that no more than two pods are ever terminated simultaneously during a rolling update process. This is to minimize the impact on service availability during the update. How would you implement this rolling update strategy using Deployment resources?

正解：

解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Update the Deployment YAML:
- Modify the 'strategy.roIIinglJpdate' section of the Deployment YAML to configure the rolling update behavior.
- Set 'maxunavailable: 1 ' to allow only one pod to be unavailable at a time during the update.
- Set 'maxSurge: 1 ' to permit only one additional pod to be created beyond the desired replica count during the update.

2. Apply the Updated Deployment: - Use ' kubectl apply -f web-app-deployment-yamr to update the Deployment. 3. Monitor the Rolling Update: - Observe the pod updates using 'kubectl get pods -I app=web-app' - You will see that during the rolling update, only one pod is terminated, while one new pod is created, ensuring that no more than two pods are ever terminated at the same time. 4. Verify the Update: - Once the rolling update is complete, check the 'updatedReplicaS field in the Deployment description Ckubectl describe deployment web-app- deployment) to verify that it matches the 'replicas' field.
