behavior has been regularized in the case where a field is removed from the applied configuration. Removed fields which have no other owners are deleted from the live object, or reset to their default value if they have one. Safe ownership transfers, such as the transfer of a `replicas` field from a user to an HPA without resetting to the default value are documented in [Transferring Ownership](https://kubernetes.io/docs/reference/using-api/api-concepts/#transferring-ownership) ([#92661](https://githu...

    Então, é uma função geradora que transfere o trabalho de "geração" para alguma outra coisa interna.

    Fazendo dessa forma, podemos colocá-la em um bloco `with`, e assim garantir que o objeto semelhante a um arquivo é fechado quando a função termina.

    Entonces, es una función generadora que transfiere el trabajo de "generar" a algo más internamente.

    Al hacerlo de esta manera, podemos ponerlo en un bloque `with`, y de esa manera, asegurarnos de que el objeto similar a un archivo se cierre después de finalizar.
