用於安裝 dcos 集群的 google 計算引擎實例中的 Docker 安裝

我一直在研究用於安裝 DCOS mesos 集群的 ansible 腳本。我一直在遵循我的 ansible 腳本中 DCOS 文件的高級安裝部分中的步驟。當我的 ansible 腳本執行時，我得到以下資訊

bash dcos_installer.sh master

結果

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.

我不知道如何修復的錯誤與儲存驅動程序有關。我正在使用執行 centos 7 的 Google GCE 實例，它們不使用 LVM，因此我無法使用推薦的 devicemapper(direct-lvm) 儲存驅動程序。

我的問題是，有沒有辦法使用 devicemapper 驅動程序，還是使用其他儲存驅動程序？

一旦它工作，我將開源我的腳本。

更新

Overlayfs 為我工作

我設法使用overlayfs解決了這個問題。我在 GCE 上的 DCOS 安裝腳本可在https://github.com/dcos-labs/dcos-gce獲得

謝謝。
