Docker错误：在Windows上设备上没有剩余空间

Question

我正在Windows 7上使用Docker并尝试从云端下载镜像。在下载后解压时，我遇到了一个错误。以下是日志片段：

cba922442da5: Downloading 5.866 GB/5.866 GB
10d186ab9b98: Download complete

 Tools docker image has been downloaded or upgraded to the newer version success
fully if already exist

已经有几个与此问题相关的线程，我尝试了它们提供的解决方案，但它们都没有起作用。我尝试使用以下命令删除所有图像，但出现了证书错误。

Answer 1

开始清理未使用/停止的图像和容器。

$ docker ps -a
$ docker images -a
$ docker container prune
$ docker image prune

你也可以登录到boot2docker并检查文件系统的使用情况：

你也可以登录到boot2docker并检查文件系统的使用情况：

> boot2docker ssh
$ df -kh

另外，您可以考虑增加boot2docker的卷大小，尽管我没有在实时文档中找到它（只有此md）。
