- A
kubectl exec web-pod-7d4f8 -c app -- logs
Why wrong: kubectl exec is for running commands inside a container, not for fetching logs.
- B
kubectl log web-pod-7d4f8 --container app
Why wrong: The command is 'kubectl logs', not 'kubectl log'.
- C
kubectl logs web-pod-7d4f8 -c app
This is the correct command to view logs of a specific container in a pod.
- D
kubectl logs web-pod-7d4f8 app
Why wrong: The correct syntax requires the -c flag before the container name: 'kubectl logs web-pod-7d4f8 -c app'.
Question 475 of 997

This KCNA practice question tests your understanding of kubernetes fundamentals. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: kubectl logs. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
✓
kubectl logs web-pod-7d4f8 -c app
Option C is correct because the `kubectl logs` command is the standard way to retrieve container logs in Kubernetes. The `-c` flag specifies the container name within the pod, which is necessary when a pod contains multiple containers. Here, the container is named 'app' inside the pod 'web-pod-7d4f8', so `kubectl logs web-pod-7d4f8 -c app` correctly fetches its logs.

Common exam traps
Common exam trap: answer the scenario, not the keyword
In the KCNA exam, candidates often confuse 'kubectl logs' with 'kubectl exec' or use incorrect flag syntax (e.g., '--container' vs '-c'). Option C is the only correct syntax because 'kubectl logs' requires the pod name and optionally '-c' for container name.

Detailed technical explanation
How to think about this question
Under the hood, `kubectl logs` communicates with the kubelet on the node hosting the pod via the API server, requesting the container's log stream from its log file (typically stored at `/var/log/pods/<namespace>_<pod-name>_<uid>/<container-name>/0.log`). The `-c` flag is essential in multi-container pods because the kubelet needs to identify which container's stdout/stderr stream to retrieve. In real-world scenarios, if you omit `-c` in a multi-container pod, kubectl will return an error prompting you to specify a container name, which is a common pitfall for candidates.
