최신 Kubernetes Application Developer CKAD 무료샘플문제 (Q155-Q160):

질문 # 155
You have a Kubernetes cluster running a critical application With multiple pods. Recently, the application has started experiencing intermittent performance issues, with some pods exhibiting high CPU utilization and others remaining idle. You suspect a network issue might be the culprit. Describe the steps you would take to investigate this issue and determine the source of the network problem.

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Gather Logs and Metrics:
- Kubernetes Events: use 'kubectl get events' to see if any events related to pods, services, or network issues are being logged.
- Container Logs: Inspect the logs of the affected pods to see if any network-related errors are reported.
- Metrics: Utilize tools like Prometheus or Grafana to monitor metrics like:
- CPU Utilization: Identify pods With high CPIJ usage.
- Network 1/0: Monitor network traffic patterns and look for anomalies.
- Latency: Check for network delays pods and services-
- Network Monitoring Tools: TOOIS like Wireshark or tcpdump can be used to capture and analyze network traffic for deeper insignts.
2. Examine Network Connectivity:
- Ping Test Run 'pings commands to check the connectivity between pods, nodes, and external services.
- Connectivity Tests: Use 'kubectl exec' to access a pod and #fform 'curl' commands to verify connectivity to services and other pods.
3. Inspect Network Configuration:
- Network Policies: Review any network policies applied to the pods, namespaces, or the cluster.
- Service Definitions: Check tne 'service' definitions to ensure tney are correctly configured and routing traffic as intended.
- Network Plugins: If using a network Plugin like Calico or Flannel, review its configuration and logs for any issues.
- Network Namespaces: Verity if the pods are using the correct network namespaces.
4. Analyze Network Traffic:
- Traffic Flow IJse tools like 'kubectl describe service' to analyze how traffic flows through the services and pods.
- Network Tracing: Utilize tracing tools to map tne flow of requests through the network and identify potential bottlenecks.
- Network Bandwidth: Check if the network bandwidth is sufficient to handle the traffic load-
5. Isolate and Resolve the Issue:
- Restart Pods: Try restarting the affected pods to see if it resolves the issue.
- Update Network Configurations: Adjust network policies, service definitions, or plugin settings if required.
- Network Troubleshooting: Utilize the collected information and network analysis tools to pinpoint the root cause.
6. Implement a Solution:
- Network Optimization: Adjust network settings or configurations to improve performance.
- Scaling: Increase the number of pods or modify deployment strategies if necessary.
- Network Monitoring: Implement continuous monitoring and alerting for potential network issues.,

질문 # 156
Context

Task:
A pod within the Deployment named buffale-deployment and in namespace gorilla is logging errors.
1) Look at the logs identify errors messages.
Find errors, including User "system:serviceaccount:gorilla:default" cannot list resource "deployment" [...] in the namespace "gorilla"
2) Update the Deployment buffalo-deployment to resolve the errors in the logs of the Pod.
The buffalo-deployment 'S manifest can be found at -/prompt/escargot/buffalo-deployment.yaml

질문 # 157
You have a Deployment named 'wordpress-deployment' that runs 3 replicas of a WordPress container. The container image is pulled from a private registry with authentication credentials stored in a secret called 'registry-credentials' _ Implement a strategy to ensure that only one replica of the Deployment is updated at a time, and the update process is triggered automatically whenever a new image is pushed to the private registry with the tag 'wordpress:latest'

정답：

설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Secret for Registry Credentials:

- Replace with the base64 encoded content of your dockerconfigjson file containing the registry credentials. 2 Update the Deployment YAML:

- Replace 'your-registry-com' with your private registry address. - Ensure the 'imagePullSecrets' section references tne 'registry-credentials' secret. - Configure the 'strategy-type' to 'Rollingupdate', and 'strategy-rollingl-lpdate.maxunavailable' to ' 1 ' to allow only one replica to be unavailable during the update. - Set 'imagePullPolicy' to 'Always' to ensure the new image is pulled every time. 3. Apply the Updated YAML: bash kubectl apply -f wordpress-deploymentyaml 4. Verify the Deployment bash kubectl get deployments wordpress-deployment 5. Trigger the Automatic Update: - Push a new image with the tag 'wordpress:latest' to your private registry. 6. Monitor the Deployment - Use 'kubectl get pods -l app=wordpress' to monitor the pod updates during the rolling update process. 7. Check for Successful Update: - After the update is complete, run 'kubectl describe deployment wordpress-deployment' to verify that the 'updatedReplicaS matcnes the 'replicas' field. Now, whenever a new image tagged 'wordpress:latest' is pushed to your private registry, Kubernetes will automatically trigger a rolling update for the 'wordpress-deployment , updating one replica at a time while ensuring availability.,

질문 # 158
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 # 159

Given a container that writes a log file in format A and a container that converts log files from format A to format B, create a deployment that runs both containers such that the log files from the first container are converted by the second container, emitting logs in format B.
Task:
* Create a deployment named deployment-xyz in the default namespace, that:
*Includes a primary
lfccncf/busybox:1 container, named logger-dev
*includes a sidecar Ifccncf/fluentd:v0.12 container, named adapter-zen
*Mounts a shared volume /tmp/log on both containers, which does not persist when the pod is deleted
*Instructs the logger-dev
container to run the command

which should output logs to /tmp/log/input.log in plain text format, with example values:

* The adapter-zen sidecar container should read /tmp/log/input.log and output the data to /tmp/log/output.* in Fluentd JSON format. Note that no knowledge of Fluentd is required to complete this task: all you will need to achieve this is to create the ConfigMap from the spec file provided at /opt/KDMC00102/fluentd-configma p.yaml , and mount that ConfigMap to /fluentd/etc in the adapter-zen sidecar container See the solution below.
