What is the function of the `kubectl exec` command?

The kubectl exec command is specifically designed to execute commands within a running container of a Pod. This command allows users to interactively run commands in the context of a container, providing direct access to the container's environment. It's particularly useful for debugging or managing applications, as it enables administrators and developers to run shell commands, scripts, or any specific binaries directly within the container.

The ability to execute commands can help troubleshoot issues directly in the environment where they occur, without needing to modify the container image or redeploy the application. This functionality also allows for real-time adjustments, checks, and validations of the application's state.

In contrast, stopping running Pods gracefully, retrieving logs, or deploying new applications are distinct operations that are managed by different kubectl commands. Each of these operations has its own dedicated command syntax and use cases, underscoring the unique role of kubectl exec in interacting with live container processes.
