Linux Foundation Certified Kubernetes Application Developer Exam 認定 CKAD 試験問題 (Q108-Q113):
質問 # 108
You are developing a container image for a .NET Core application tnat requires a specific version of tne .NET Core SDK to be installed. How would you ensure that the correct SDK version is available within your Docker image during the build process?
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Choose .NET SDK Base Image:
- Select a base image that includes the desired .NET Core SDK version from Docker Hub.
- Example (for .NET core 3.1 SDK):
dockerfile
FROM mcr-microsoft.com/dotneVsdk:3.1
2. Copy Application Code:
- Copy your .NET Core application code into the Docker image.
- Example:
dockerfile
COPY
3. Build the Application:
- Use the 'RIJN' instruction to build your .NET Core application using the 'dotnet publish' command.
- Example:
dockerfile
RUN dotnet publish -c Release -o /app
4. Define Runtime Image (Optional):
- Create a second stage Dockerfile that uses a smaller base image, copying only the published application files.
- This optimizes the final image size.
- Example:
dockerfile
FROM mcr-microsoft.com/dotnet/aspnet:3.1
COPY -from=build /app /app
WORKDIR /app
ENTRYPOINT ["dotnet", "your-app.dll"]
5. Build and Deploy:
- Use 'docker build' to construct the final Docker image.
- Deploy this image to your Kubernetes cluster.
質問 # 109
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.
正解：
解説：
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.
質問 # 110
Refer to Exhibit.
Set Configuration Context:
[student@node-1] $ | kubectl
Config use-context k8s
Context
You sometimes need to observe a pod's logs, and write those logs to a file for further analysis.
Task
Please complete the following;
* Deploy the counter pod to the cluster using the provided YAMLspec file at /opt/KDOB00201/counter.yaml
* Retrieve all currently available application logs from the running pod and store them in the file /opt/KDOB0020l/log_Output.txt, which has already been created
正解：
解説：
Solution:
To deploy the counter pod to the cluster using the provided YAML spec file, you can use the kubectl apply command. The apply command creates and updates resources in a cluster.
kubectl apply -f /opt/KDOB00201/counter.yaml
This command will create the pod in the cluster. You can use the kubectl get pods command to check the status of the pod and ensure that it is running.
kubectl get pods
To retrieve all currently available application logs from the running pod and store them in the file /opt/KDOB0020l/log_Output.txt, you can use the kubectl logs command. The logs command retrieves logs from a container in a pod.
kubectl logs -f <pod-name> > /opt/KDOB0020l/log_Output.txt
Replace <pod-name> with the name of the pod.
You can also use -f option to stream the logs.
kubectl logs -f <pod-name> > /opt/KDOB0020l/log_Output.txt &
This command will retrieve the logs from the pod and write them to the /opt/KDOB0020l/log_Output.txt file.
Please note that the above command will retrieve all logs from the pod, including previous logs. If you want to retrieve only the new logs that are generated after running the command, you can add the --since flag to the kubectl logs command and specify a duration, for example --since=24h for logs generated in the last 24 hours.
Also, please note that, if the pod has multiple containers, you need to specify the container name using -c option.
kubectl logs -f <pod-name> -c <container-name> > /opt/KDOB0020l/log_Output.txt The above command will redirect the logs of the specified container to the file.
質問 # 111
You have a Deployment running a container image for a web application. The application's configuration files are currently stored within the image itself. you want to move the configuration files to a ConfigMap so that they can be updated independently or the application image. Describe the steps involved in modifying the Deployment and creating a ConfigMap to achieve this separation.
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ConfigMap:
- Create a ConfigMap using 'kubectl create configmap' with the configuration files. For example:
kubectl create configmap webapp-config -from-literal=config.json='{"port": 8080, "database_url": "mongodb://localhost27017"}'
- Replace 'config_json' with the name of your configuration file and the JSON content with your actual configuration values.
2. Modify the Deployment:
- Modify your Deployment YAML file to mount the ConfigMap as a volume. Here's an example:
- Modify your application code to read configuration files from '/etctwebapp/config' 3. Apply the Changes: - Apply the updated Deployment using 'kubectl apply -f deployment_yamr 4. Verify the Update: - Check the logs of the pods using 'kubectl logs -f You should see the application loading configuration values from the ConfigMap. 5. Update the Configuration: - You can now update the configuration files within the ConfigMap without rebuilding the image. For example.
- This will update the ConfigMap and trigger a rolling update of the Deployment, effectively updating the application configuration without rebuilding the image.
質問 # 112
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
正解：A
