최신 Kubernetes Application Developer CKAD 무료샘플문제 (Q154-Q159):

질문 # 154
You are developing a new microservice that requires access to a database deployed in a different namespace. You want to configure a ServiceAccount and RoleBinding to provide the necessary permissions for the microservice to connect to the database.

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a ServiceAccount:
- Create a ServiceAccount in the namespace where our microservice is deployed:

2. Create a Role: - Create a Role in the namespace where the database is deployed, granting access to the database resources:

3. Create a ROIeBinding: - Create a RoleBinding in the database namespace to bind the Role to the ServiceAccount:

4. Apply the Configuration: - Apply the created ServiceAccount, Role, and Roledinding using 'kubectl apply -r commands: bash kubectl apply -f my-microservice-sa_yaml kubectl apply -f my-database-access-role-yaml kubectl apply -f my-database-access-rolebinding.yaml 5. Configure the Microservice: - Mount the ServiceAccount token as a secret within the microservice's pod:

6. Verify Permissions: - Access the database from the microservice pod to verify that the required permissions are granted.

질문 # 155
You are building a Kubernetes application that involves a microservice architecture with multiple pods for each service. One of your services requires a sidecar container to handle logging and monitoring. How would you design the pod structure and define the relationships between the application container and the sidecar container?

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Pod Specification:
- Create a pod definition file (e.g., 'pod.yaml').
- Include the 'apiVersion', 'kind', 'metadata' (name, labels), and 'spec' sections.
2. Define Application Container:
- Within the 'spec.containerS section, define the primary application container:
- 'name': Provide a descriptive name for the application container (e.g., 'app').
- Simage: Specify the Docker image for the application.
- 'ports': Define any ports that the application exposes.
- 'resources': (Optional) Specify resource requests and limits for the application container.
3. Define Sidecar Container.
- Add another container definition within the 'spec-containers' section for the sidecar:
- 'name': Provide a name for the sidecar container (e.g., Slogger').
- 'image': Specify the Docker image for the sidecar container (e.g., "busybox'
- 'command': Define the command to run within the sidecar. This might involve using a logging agent, monitoring tool, or any other custom script.
- 'volumeMountss: (Optional) If the sidecar needs access to shared data, mount volumes here.
4. Define Shared Volumes (Optional):
- If necessary, create a 'spec-volumes' section to define any shared volumes that both containers can access. This might include:
- 'emptyDir': For temporary data that only exists within the pod.
- 'persistentVolumeClaim': To use a persistent volume claim for shared data that persists beyond pod restarts.
5. Configure Container Relationships:
- Ensure that the 'name' of the application container and sidecar container is the same as the 'name' used in the 'volumeMounts' section.
Example YAML:

- The pod named 'my-app-pod' includes two containers: 'app' (the primary application) and 'logger' (the sidecar). - The 'loggers container uses a 'command' to simulate logging activity. - Both containers can access the 'logs' volume, which is an empty directory. Important Note: - The sidecar container should ideally be configured to interact with the application container. This might involve using shared volumes, environment variables, or inter-process communication mecnanisms to facilitate data exchange or Signal passing. - Remember to adapt the example to your specific application requirements, choosing the appropriate container images, commands, and volumes.]

질문 # 157
You have a microservice application that is deployed as a Deployment. You want to implement a mechanism to handle temporary network issues or other transient failures that may occur during the application's communication with external services. Explain how you can use readiness probes and liveness probes in combination with a restart policy to address these failures.

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Readiness Probes:
- Add a 'readinessProbe' to the container spec of your application pods.
- The probe should check the health and readiness of the application to receive incoming requests.
- This probe should be executed periodically.
- If the probe fails, the pod will be considered not ready and won't receive traffic.
- Example using a TCP socket check:

2. Define Liveness Probes: - Add a 'livenessProbe' to the container spec of your application pods- - This probe should check the health of the application pod itself. - It should be executed periodically to detect issues that might not affect readiness but indicate a problem with the application. - If the liveness probe fails for a specified number of consecutive attempts, the pod will be restarted. - Example using a HTTP endpoint cneck:

3. Set Restart Policy: - Ensure that the restart policy for the pod is set to 'Always' (the default) to automatically restart the pod upon failure detected by the liveness probe. 4. Implement Health Check Endpoints: - Implement the health check endpoints within your application (e.g., ' Ihealth' for the liveness probe, a simple TCP connection for the readiness probe) to allow probes to assess the nealth of the application and its dependencies. 5. Verify and Monitor: - Deploy the updated Deployment and simulate network failures or other transient issues. - Monitor the pods' health and observe that they are automatically restarted and marked as not ready when necessary, ensuring continued application availability despite temporary disruptions.

질문 # 158
You are building a container image for a Spring Boot application that connects to a MySQL database. The application requires specific environment variables, such as the database nostname, username, password, and port. How would you define these environment variables Within the Docker-file to ensure the application runs correctly in a Kubernetes cluster?

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
1. Define Environment Variables in Docker-file:
- Utilize the 'ENV' instruction within your Dockerfile to set the necessary environment variables.
- These variables will be accessible to your Spring Boot application during runtime.
- Example:
dockerfile

2. Build the Docker Image: - Construct your Docker image using the Docker-file. - Run the following command: 'docker build -t your-image-name 3. Deploy to Kubernetes: - Create a Deployment or Pod in Kubernetes that utilizes your built image. - Ensure the pod's environment variables align with the ones defined in your Dockerfile. - Example (Deployment YAML):

4. Verify Application Functionality: - Access your deployed application in the Kubernetes cluster. - Verify that it connects successfully to the database and operates as expected.
