You want to view the logs of a pod named 'web-pod' that has two containers: 'nginx' and 'sidecar'. Which command correctly retrieves the logs from the 'nginx' container?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
kubectl logs web-pod -c nginx
The correct command uses the proper syntax: `kubectl logs <pod-name> -c <container-name>`. Option B follows this syntax correctly. Option A places the container flag before the pod name, which is invalid. Option C omits the -c flag, which is required when the pod has multiple containers. Option D uses the long form --container, which is valid but the question expects the short form as seen in B. Therefore, B is the best answer.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

kubectl logs -c nginx web-pod
Why it's wrong here
Missing -f flag for streaming; also syntax is unconventional but container flag is present.

Why this is correct
Correctly specifies the container with -c, but lacks -f flag to stream logs.
- ✗
kubectl logs web-pod nginx
Why it's wrong here
Incorrect syntax; container must be specified with -c flag.

kubectl logs web-pod --container nginx
Why it's wrong here
Correctly uses --container, but missing -f flag for streaming.
