Я пытаюсь оценить производительность одного из моих серверов go, работающих внутри модуля. Однако появляется сообщение об ошибке слишком много открытых файлов. Есть ли возможность установить ulimit в кубернетах?

Когда я использовал locust для проверки производительности сервера, я получил следующую ошибку.
