docker 使用 Linux 容器为 Windows 导入 Docker 没有 space 留在设备错误上，存储驱动程序：overlay2

Question

我正在导入一个 15 GB 的大型数据库图像（我可以毫无问题地导入 9.5 GB 的图像。）使用 Linux 容器 Docker for Windows。我正在使用 Windows 10 Pro 1803, build 17134.1006.

错误：

PS C:\WINDOWS\system32> docker import "C:\Users\oscar\Desktop\MSSQL.tar" mssql
Error response from daemon: Error processing tar file(exit status 1): write /var/opt/mssql/data/TestDatabase.mdf: no space left on device

我已按照此处的建议删除了所有悬空卷和未使用的图像：

在阅读存储驱动程序时，我遇到了 devicemapper 和其他驱动程序的一些限制。

https://docs.docker.com/engine/reference/commandline/dockerd/#options-per-storage-driver

对于devicemapper：

Specifies the size to use when creating the base device, which limits the size of images and containers. The default value is 10G. Note, thin devices are inherently “sparse”, so a 10G device which is mostly empty doesn’t use 10 GB of space on the pool. However, the filesystem will use more space for the empty case the larger the device is.

https://docs.docker.com/engine/reference/commandline/dockerd/#dmbasesize

我找不到 overlay2 的任何图像限制，默认情况下只有 20 GB 的容器限制。

Specifies the size to use when creating the sandbox which is used for containers. Defaults to 20G.

我尝试运行示例命令，但出现错误。 dockerd 未映射到命令。

C:\>dockerd --storage-opt size=40G
'dockerd' is not recognized as an internal or external command,
operable program or batch file.

https://docs.docker.com/engine/reference/commandline/dockerd/#size

既然它无论如何都应该工作，我不确定我是否走在正确的道路上。

存储 space 应该不是问题：

Answer 1

我应该学习阅读...阅读它作为 55.29 GB 未使用。在 Docker -> Settings -> Advanced 中增加 Disk image max size 后，一切都开始工作了。
