1. This is the generator function. It's a "generator function" because it contains `yield` statements inside.
2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.
3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function (`iterfile`).

2. Al usar un bloque `with`, nos aseguramos de que el objeto similar a un archivo se cierre después de que la función generadora termine. Así, después de que termina de enviar el response.
3. Este `yield from` le dice a la función que itere sobre esa cosa llamada `file_like`. Y luego, para cada parte iterada, yield esa parte como proveniente de esta función generadora (`iterfile`).

- For `kubectl`, `--server-side` now migrates ownership of all fields used by client-side-apply to the specified `--fieldmanager`. This prevents fields previously specified using kubectl from being able to live outside of server-side-apply's management and become undeleteable.
