En esta página se describe cómo sondear de forma programática los recursos de operación de larga duración devueltos por los métodos de las APIs de Service Infrastructure que tardan mucho tiempo en completarse, como service.rollouts.create.
Una vez que se haya completado una operación, el campo done se establecerá en true.
Para sondear una operación, invoca repetidamente el método operations.get con un tiempo de espera recomendado de 10 segundos hasta que se complete la operación:
