【问题描述】：

我在运行 Windows Server 2019 的开发测试实验室中使用 Azure DSVM。我正在尝试安装 Docker 并努力让我能够从 Azure ML 服务环境运行本地实验。

我想在 Docker 上构建一个定制的 Linux 容器——我相信通过阅读其他一些在线帖子在 Windows 上是可能的（由于各种原因，我不能使用 Linux 主机）。当我尝试创建包含WORKDIR ... 步骤的此类图像时，我收到“容器 ***** 在 CreateProcess 期间遇到错误：Windows 系统调用失败”错误。

我在 DSVM（标准 D2s_v3）上安装了 Docker，方法是在创建时添加“Docker”工件，然后运行以下命令来启用 Linux 容器：

$> Install-WindowsFeature -Name Hyper-V -IncludeManagementTools -Restart
$> [Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", "1", "Machine")

运行一个简单的 Linux 容器可以正常工作：

$> docker run --rm -it alpine:latest
/ # ls
bin    dev    etc    home   lib    media  mnt    opt    proc   root   run    sbin   srv    sys    tmp    usr    var
/ #

为了构建自定义镜像，我使用了一个简单的 Dockerfile，如下所示：

FROM alpine:latest

WORKDIR /abm

图片成功出现在build：

$> docker build --no-cache -t abm-alpine:workdir -f .\abm-alpine.Dockerfile .
Sending build context to Docker daemon  2.048kB
Step 1/2 : FROM alpine:latest
 ---> a187dde48cd2
Step 2/2 : WORKDIR /abm
 ---> 495f8ecb3a0e
Removing intermediate container 219e91296e47
Successfully built 495f8ecb3a0e

当我run 图片时，我收到以下错误：

$> docker run --rm -it abm-alpine:workdir

我尝试了各种日志（例如Get-WinEvent -LogName Microsoft-Windows-Hyper-V-Compute-Operational 和Get-EventLog -LogName Application -Source Docker），但看不到有关错误的任何其他信息。

谁能建议是否可以在 Windows DSVM 上创建基于 Linux 的自定义映像？如果是，谁能告诉我可能是什么问题或我可以采取的任何其他故障排除步骤？

谢谢！
