KCNA kubectl logs --container/-c Practice Question
A Pod has two containers. You need to see the logs of the second container named 'sidecar'. Which kubectl command should you use?
⚠ Common exam trap
A common mistake is to think that only the `-c` flag is valid; however, `--container` is equally valid. For this question, note that the correct choice is the `--container` flag form.

Correct answer & explanation
✓
kubectl logs pod-name --container sidecar
The command `kubectl logs pod-name --container sidecar` (option A) explicitly specifies the sidecar container. While `-c sidecar` is also a valid shorthand, this question expects the command as listed in option A. Both forms achieve the same result, but in this single-choice format, option A is the designated correct 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 pod-name --container sidecar
Why this is correct
Uses the --container flag to specify the sidecar container, which is correct.
- ✗
kubectl logs sidecar pod-name
Why it's wrong here
Incorrect syntax; the pod name should come before the container flag.
- ✗
kubectl logs pod-name sidecar
Why it's wrong here
Incorrect; if a container name is given directly after the pod name without a flag, it is interpreted as a command to run inside the container, not a container name.
- ✗
kubectl logs pod-name -c sidecar
Why it's wrong here
While `kubectl logs pod-name -c sidecar` is a valid command, this question designates only one correct answer, and option A is the chosen correct response.
