最新的 Kubernetes Application Developer CKAD 免費考試真題 (Q34-Q39):

問題 #34
You need to implement a strategy to manage and control the access of pods to specific resources in your Kubernetes cluster. Explain how you would use PodSecurityPolicies to enforce fine-grained access control.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create a PodSecurityPolicy:
- Create a new YAML file (e.g., 'pod-security-policy.yaml') to define your PodSecurityPolicy.
- Specify the name of the PodSecurityPolicy and the namespace where it will be applied.
- Define the security policies for the PodSecurityPolicy. You can use the 'kubectl create -f pod-security- policy.yamP command to apply the PodSecurityPolicy.

3. Apply the PodSecurityPolicy to Deployments: - Update the 'podSecurityContext' field in your Deployment YAML to specify the PodSecurityPolicy.

4. Verify the PodSecurityPolicy: - Use the 'kubectl get podsecuritypolicy' command to list the applied PodSecurityPolicies and confirm their status. 5. Test the Restrictions: - Try to create pods that violate the rules defined in the PodSecurityPolicy. - Verify that the PodSecurityPolicy is effectively preventing the creation of pods that do not meet the defined security policies.,

問題 #35
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

問題 #36
You are designing a container image for a Java application that utilizes a specific version of Maven. Explain how you would include this Maven version Within tne Docketflle to ensure consistent builds across different environments.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Select Base Image:
- Choose a base image that provides the necessary Java runtime environment (like OpenJDK) and a suitable operating system (e.g., Debian, Ubuntu).
- Example:
dockerflle
FROM openjdk: 11 -jre-slim-buster
2. Install Maven (Specific Version):
- Utilize the instruction to download and install the required Maven version using 'wget' and commands.
- Example:
dockefflle
RUN wget -nv https://apache.org/dyn/closer.lua/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz
&& tar -xzf apache-maven-3.8.6-bin.tar.gz -C lusr/local
&& In -s /usr/local/apache-maven-3.8.6/bin/mvn /usr/bin/mvn
&& rm apache-maven-3.8.6-bin.tar.gz
3. Copy Application Code:
- Copy your Java application code and its 'pom.xmr file to the Docker image-
- Example:
dockerfile
COPY
4. Build Java Application:
- Utilize the 'RUN' instruction to build your Java application using the 'mvn' command.
- Example:
dockeffile
RUN mvn clean package
5. Define Entrypoint (Optional):
- If your application requires specific entrypoint commands, define them in your Docker-file.
- Example:
dockefflle
ENTRYPOINT ["java", "-jar", "target/your-app.jar"]
6. Build and Deploy:
- Build tne Docker image using 'docker build'
- Deploy the image to Kubernetes.
- This ensures that the specific Maven version is used when building your application.

問題 #37
You have a Deployment named 'api-deployment' that runs an API server. The API server handles sensitive data and must have strong security measures. You want to ensure that all pods within the Deployment are running with a specific security context that limits their capabilities. Describe the steps to configure a Securitycontext in the Deployment to enforce these security restrictions.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the SecurityContext:
- Add a 'securityContext' section to the container definition Within the Deployment's template.
- Define the desired security restrictions Within the 'securityContext sectiom
- 'runAsLJser': Specifies the user ID under which the container should run.
- 'runAsGroup': Defines the group ID for the container.
- 'tsGroup': Sets the supplemental group ID for the container, giving access to specific files and directories.
- 'readOnlyRootFilesystem': Specifies whether the container should have read-only access to the root filesystem.
- 'capabilities': Configures the allowed capabilities for the container, limiting its privileges.

2. Apply the Deployment: - Use 'kubectl apply -f api-deployment_yamr to update the Deployment with the security context configuration. 3. Verify the Security Context: - Examine the pod details using 'kubectl describe pod -I app=api-server' to confirm that the SecurityContext is applied to the containers. 4. Test Security Measures: - Run tests to ensure the security context is effectively limiting the capabilities of the API server pods.

問題 #38
You are running a microservices application on Kubernetes, and you need to restrict the communication between your services to specific ports. For example, your 'frontend' service should only be allowed to communicate with the 'backend' service on port 8080. How would you configure this using NetworkPolicy in Kubernetes?

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the NetworkPolicy:
- Create a new YAML file (e.g., 'frontend-network-policy.yaml') to define the network policy.
- Specify the name of the NetworkPolicy and the namespace where it will be applied.
- Include the following elements within the 'spec' section:
- 'podSelector' to target the 'frontend' pods.
- 'ingress' section to define inbound traffic rules.
- 'egress' section to define outbound traffic rules.

2. Apply the NetworkPolicy: - Apply the NetworkPolicy to your cluster using the following command: bash kubectl apply -f frontend-network-policy.yaml 3. Verify the NetworkPolicy: - Use the 'kubectl get networkpolicy' command to list the applied NetworkPolicies and confirm the status. 4. Test the Restrictions: - From a 'frontend' pod, attempt to connect to the 'backend' service on port 8080. - Attempt to connect to other services or ports on the backend or external networks. - Verify that the communication restrictions defined in the NetworkPolicy are working as expected.
