Which command is used to retrieve logs from a container in a Pod?

The command used to retrieve logs from a container in a Pod is "kubectl logs." This command allows you to view the logs generated by a specific container within a Pod, which is essential for troubleshooting and monitoring the behavior of applications running in Kubernetes.

By using "kubectl logs," you can access the standard output and standard error streams from the container, providing valuable insights into the application’s operations, errors, and events. You can specify the Pod name and, if there are multiple containers within the Pod, you can also indicate which container's logs to retrieve.

Other commands serve different purposes. For instance, "kubectl describe" provides detailed information about a resource, such as a Pod’s configuration and status, but does not show logs. Meanwhile, "kubectl exec" is used to execute commands inside a running container, which is useful for debugging but not specifically for retrieving logs. Lastly, "kubectl attach" allows you to attach to a running container's standard input, output, and error streams, but it does not provide accumulated logs like "kubectl logs" does. Thus, "kubectl logs" is the most appropriate command for the task of retrieving logs from a container within a Pod.
