Привет, я совершенно новичок в docker и nifi, и мне нужно настроить nifi в docker, но я получаю следующую ошибку.

Текст ошибки ниже или (скриншот терминала с ошибкой)

Основываясь на моих исследованиях, упоминается, что мне нужно обновить несколько свойств в файле nifi.properties, но я не уверен, как я могу установить их в образе докера. Пожалуйста, помогите.

Просто добавьте NIFI_SENSITIVE_PROPS_KEY переменную среды как переменную среды в файл nifis docker-copmose. Это может быть случайная строка, но убедитесь, что она содержит не менее 12 символов (в противном случае NiFi не сможет ее обработать).
