在 Google 计算引擎实例内安装 Docker 以安装 dcos 集群

我一直在编写一个用于安装 DCOS mesos 集群的 ansible 脚本。我一直在按照 ansible 脚本中 DCOS 文档的高级安装部分中的步骤进行操作。当我的 ansible 脚本运行时，我得到了以下信息

bash dcos_installer.sh master

结果

Checking Docker is configured with a production storage driver:  WARNING: Usage of loopback devices is strongly discouraged for production use. Either use `--storage-opt dm.th

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.

我不知道如何修复的错误与存储驱动程序有关。我正在使用运行 centos 7 的 Google GCE 实例，它们不使用 LVM，因此我无法使用推荐的 devicemapper(direct-lvm) 存储驱动程序。

我的问题是，有没有办法使用 devicemapper 驱动程序，或者我是否使用其他存储驱动程序？

一旦我的脚本可以运行，我就会开源。

更新

Overlayfs 对我有用

答案1

我设法使用 overlayfs 解决了这个问题。我的 GCE 上的 DCOS 安装脚本可从以下位置获取https://github.com/dcos-labs/dcos-gce

谢谢。
