질문 # 65
Exhibit:
Context
A web application requires a specific version of redis to be used as a cache.
Task
Create a pod with the following characteristics, and leave it running when complete:
* The pod must run in the web namespace.
The namespace has already been created
* The name of the pod should be cache
* Use the Ifccncf/redis image with the 3.2 tag
* Expose port 6379
정답：B
질문 # 66
Refer to Exhibit.
Task:
Create a Deployment named expose in the existing ckad00014 namespace running 6 replicas of a Pod.
Specify a single container using the ifccncf/nginx: 1.13.7 image Add an environment variable named NGINX_PORT with the value 8001 to the container then expose port 8001

질문 # 67
You are building a Kubernetes application that manages a fleet of autonomous vehicles. Each vehicle is represented by a custom resource called 'Vehicle'. You need to implement a CRD that defines the 'Vehicle' resource, including its required fields (like 'location', and 'status'), and ensures that the 'status' field can only be updated by the controller managing the vehicles.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Vehicle Custom Resource Definition (CRD):
- Create a YAML file named 'vehicle-crd-yaml with the following content:
2. create the CRD: - Apply the CRD definition using 'kubectl apply -f vehicle.crd.yaml'. 3. Validate the CRD: - Verity that the CRD is created successfully by running kubectl get crd vehicles-example.com'. 4. Create a Vehicle Resource: - Create a YAML file named 'vehicle-yamr with the following content:
5. Create the Vehicle Resource: - Apply the vehicle resource definition using 'kubectl apply -f vehicle-yamr 6. Verify the Vehicle Resource: - Ensure that the vehicle resource is created successfully by running 'kubectl get vehicles -n default 7. Update the 'status' Field: - Attempt to update tne 'status' field directly using 'kubectl patch vehicle vehicle-I -n default -p '{"spec": {"status": "driving"))" - Observe that the update fails because the 'status' field is considered immutable and can only be updated by the controller managing the vehicles. 8. Implement a Controller: - Create a controller that reads the 'Vehicles resources, updates the 'status' field based on the vehicle's state, and handles any errors. This controller should have read-only access to the 'spec' field and write access to the 'status' field. 9. Deploy the Controller: - Deploy the controller as a Deployment or a StatefulSet in Kubernetes- 10. IJpdate the 'status' Field through the Controller. - Trigger the controller to update the 'status' field of the 'vehicle-1' resource. - Verot that the 'status' field is updated successfully without violating the immutability rule. Key Points: - The CRD defines the 'Vehicle' resource schema and its required fields. - The 'status' field is marked as immutable to prevent direct updates by users- -A controller is responsible for updating the 'status' field based on the vehicle's state and ensuring data integrity. - This setup ensures that the 'status' field is always consistent and updated by the designated controller, maintaining data integrity and preventing accidental modifications.,
질문 # 68
You are building a Kubernetes application tnat requires persistent storage for its dat a. The application needs to be able to access the data even if the pod is restarted or deleted. You have a PersistentVolumeClaim (PVC) defined for this purpose.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a PersistentVolume (PV):
- Define a PV with a suitable storage class, access modes (ReadWriteOnce), and a capacity that meets your application's storage requirements.
- Example:
2. Create a PersistentVolumeClaim (PVC): - Define a PVC with the desired storage class and access modes. - Specify the desired storage capacity. - Example:
3. Create a Deployment With the PVC: - In the Deployment YAML, define a volume mount that uses the PVC you created_ - Specify the volume mount path within the container. - Example:
4. Create the Deployment: - Apply the Deployment YAML using 'kubectl apply -f my-app-deployment.yamr 5. Verify the Deployment - Check the status of the Deployment using 'kubectl get deployments my-app' - Verify that the Pod is running and using the PersistentVolumeClaim. - You can also check the pod's logs for confirmation that the data is stored in the mounted volume.
질문 # 69
You have a Deployment for a stateless application that involves several containers. You want to expose this application as a single service using a Service resource- You also want to configure the Service to use a specific label selector to target the correct pods and to ensure that the Service uses a round-robin load balancing strategy for distributing traffic across the pods. Explain how you can create the Service resource and configure it to acnjeve this.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Service:
- Create a Service resource that defines how the pods of your application will be accessed externallv
- Specify a unique name for the Service and define the port mapping-
- Example:
2. Set Selector: - Use the 'selector field to specify the label that the Service should use to identify the pods it should target - Ensure that the pods of your Deployment are labeled with the specified 'app: myapp' label. 3. Configure Load Balancing: - The default load balancing strategy for Kubernetes Services is round-robin, which distributes traffic evenly across the available pods. - No additional configuration is needed for this strategyc 4. Deploy and Test: - Apply the Service YAML file. - Test the Service by accessing it from outside the cluster. - Ensure that the traffic is distributed evenly across the pods using the round-robin strategy. 5. Optional: External Access: - If you want to expose the Service to the internet, you can set the Service 'type' to 'Load8alancer'. This will create a LoadBalancer resource (often an external IP address) that routes traffic to the Service.
