最新的 Kubernetes Application Developer CKAD 免費考試真題 (Q102-Q107):

問題 #102
You are building a container image for a Python application that requires several external libraries. You want to ensure that the image is as small as possible while still containing all necessary dependencies. What strategy should you use to optimize the image size? Explain your approach and provide a code example.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
I). Use a multi-stage Dockerfile: This allows you to have separate build and runtime stages. The build stage can include all necessary tools and dependencies for building the application, while the runtime stage only includes the essential components needed to run the application.

2. Minimize the base image: Choose a base image With only the necessary operating system components, tools, and libraries. I-Ising a slim image variant like 'python:3.9-slim' reduces the image Size significantly. 3. Use a lightweight package manager: Employ a lightweight package manager like 'pip' for installing Python dependencies. This helps keep the image lean 4. Optimize dependencies: Analyze your 'requirements.txt' file and remove any unnecessary dependencies or packages. This is crucial for reducing the overall size of the image. 5. Use caching wisely: In the 'Dockerfile', leverage caching by placing 'COPY commands for your application code before 'RUN' commands. This prevents unnecessary rebuilds of the image when only the application code changes. 6. Consider dependency bundling: If your application relies on specific library versions, consider using a tool like 'pip-tools' to lock down dependencies. This avoids issues where updates to external libraries introduce compatibility problems. 7. Remove unnecessary files: After building your image, inspect the image layers and identify any unneeded files. Remove these files using 'docker image prune' to further reduce image size.

問題 #103

Context
You are asked to prepare a Canary deployment for testing a new application release.
Task:
A Service named krill-Service in the goshark namespace points to 5 pod created by the Deployment named current-krill-deployment

1) Create an identical Deployment named canary-kill-deployment, in the same namespace.
2) Modify the Deployment so that:
-A maximum number of 10 pods run in the goshawk namespace.
-40% of the krill-service 's traffic goes to the canary-krill-deployment pod(s)

問題 #104
You are developing a multi-container application that includes a web server, a database, and a message broker. You want to ensure that the database and message broker start before the web server to avoid dependency issues. How can you design your deployment to achieve this?

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define Pod with Containers:
- Create a 'Pod' definition with three containers: 'web-server', 'database' , and 'message-broker
- Include the appropriate image names for each container.

2. Implement Init Containers: - Define ' initcontainers' within the 'Pod' spec to run containers before the main application containers. - Use 'initContainers' to set up the database and message broker:

3. Apply the Pod Definition: - Apply the 'Pod' definition using 'kubectl apply -f multi-container-app.yamr 4. Verify Container Startup Order: - Check the pod logs using 'kubectl logs -f multi-container-app'. You will observe the init containers ('database-init and 'message-broker-init') starting first, followed by the main containers ('web-server', 'database' , and 'message-broker'). Note: In this example, the 'database-init and 'message-broker-init containers simply print a message. You can replace these with actual initialization scripts or commands relevant to your specific database and message broker services.

問題 #105
You have a Deployment named 'database-deployment' that runs a PostgreSQL database container. You want to enforce the following security restrictions:
- The container should only be allowed to run with the I-IID 1000.
- The container should be able to access a specific hostPath volume mounted at '/db-data' for storing database data.
- The container should not be allowed to escalate privileges.
- The container should only have the 'NET BIND SERVICE capability, allowing it to listen on specific ports.
You need to define a SecurityContext in the Deployment configuration to enforce these 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
- Create a 'securitycontext' section within the 'spec-template-spec-containers' block for your 'database-deployment container-
- Set 'runAsIJsers to '1000' to enforce running as UID 1000.
- Set 'allowPrivilegeEscalation' to 'false' to disable privilege escalation-
- In the 'capabilities' sectiom
- Set 'drop' to an array containing all capabilities except 'NET BIND_SERVICE'
- Set 'add' to an array containing 'NET BIND SERVICE
- Define a 'volumeMount' to mount the '/db-data' hostPath volume.
Solution (Step by Step) :
1. Define the SecurityContext:
- Create a 'securityContext' section within the block for your 'database-deployment container.
- Set 'runAslJser' to "1000' to enforce running as UID 1000.
- Set 'allowPriviIegeEscaIation' to 'false' to disable privilege escalation.
- In the 'capabilities' section:
- Set 'drop' to an array containing all capabilities except 'NET BIND SERVICE
- Set 'add' to an array containing
- Define a 'volumeMount' to mount the '/db-data' hostPath volume.

2. Create the Deployment: - Apply the Deployment YAML file using 'kubectl apply -f database-deployment.yaml. - The 'securityContext' restricts the container's benavior and capabilities. - Setting 'runAslJser' to '1000' forces the container to run as the specified UID. - 'allowPrivilegeEscalation' set to 'false' prevents tne container from gaining higner privileges. - The 'capabilities' section controls specific capabilities. 'drop' removes unwanted capabilities, while 'add' grants specific capabilities. In this case, the container is allowed to use the capability, enabling it to bind to specific ports. - The 'volumeMount defines the mount point for the hostPath volume, providing access to the specified directory tor database data. This configuration ensures that the 'database-deployment container runs with the specific IJID, cannot escalate privileges, and only has the 'NET BIND SERVICE' capability, while accessing the hostPath volume for database data. This provides a secure environment for your database container.,

問題 #106
You are deploying a new application named 'cnat-app' that requires 5 replicas. You want to implement a rolling update strategy that ensures only one pod is unavailable at any given time, while also allowing for the creation of two new pods simultaneously. This will help to ensure that the application remains available during the update process.

答案：

解題說明：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Update the Deployment YAML.
- Update the 'replicas' to 5.
- Define 'maxunavailable: and 'maxSurge: 2' in the 'strategy.roIIingUpdate' section.
- Configure a 'strategy-type' to 'Rollingupdate' to trigger a rolling update when the deployment is updated.
- Add a 'spec-template-spec-imagePullPolicy: Always' to ensure that the new image is pulled even if it exists in the pod's local cache.

2. Create the Deployment: - Apply the updated YAML file using 'kubectl apply -f chat-app-deployment.yamr 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments chat-app-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'example/chat-app:latest' Docker Hub repository. 5. Monitor the Deployment - Use ' kubectl get pods -l app=chat-app' to monitor the pod updates during the rolling update process. You will observe that one pod is terminated at a time, while two new pods with the updated image are created- 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment chat-app-deployment to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
