Установка Docker внутри экземпляра вычислительного движка Google для установки кластер DCOS

Я работал над скриптом ansible для установки мезокластера DCOS. Я выполнял шаги, описанные в разделе расширенной установки документации DCOS в моем скрипте ansible. Я получаю следующее, когда мой сценарий ansible запускает

bash dcos_installer.sh master

FAIL (devicemapper, /dev/loop0)
Docker is configured to use the devicemapper storage driver with a loopback
device behind it. This is highly recommended against by Docker and the
community at large for production use[0][1]. See the docker documentation on
selecting an alternate storage driver, or use alternate storage than loopback
for the devicemapper driver.

Ошибки, которые я не знаю, как исправить, связаны с драйвером хранилища. Я использую экземпляры Google GCE под управлением centos 7, они не используют LVM, поэтому я не могу использовать рекомендуемый драйвер хранилища devicemapper (direct-lvm).

У меня вопрос: есть ли способ использовать драйвер devicemapper или я использую другой драйвер хранилища?

Я открою исходный код своего скрипта, как только он заработает.

Overlayfs у меня сработал
