Question

查看从托管Linux预览到托管VS2017的构建定义的代理程序池更改，我们的构建因以下错误而开始失败。请让我知道是否有人知道解决方案吗？

FROM nginx

最新：从库/ nginx中提取

清单清单条目中找不到未知的匹配清单

[错误] C：\ Program Files \ Docker \ docker.exe失败，返回码：1

托管的VS2017为您提供了一个在Windows Server 2016上运行的VM，并且如果您检查清单中的“ nginx” docker映像，如下所示-

docker manifest inspect nginx
{
   "schemaVersion": 2,
   "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
   "manifests": [
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "size": 948,
         "digest": "sha256:5b49c8e2c890fbb0a35f6050ed3c5109c5bb47b9e774264f4f3aa85bb69e2033",
         "platform": {

            "os": "linux"
         }
      },
      {

         "size": 948,
         "digest": "sha256:eb5069e1c31931141bc0bf662c3cc9bf066301fc6e32c5496698e3ded105bf57",
         "platform": {
            "architecture": "arm",
            "os": "linux",
            "variant": "v7"
         }
      },
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",

            "architecture": "arm64",
            "os": "linux",

         }
      },
      {

         "platform": {
            "architecture": "386",
            "os": "linux"
         }
      },
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "size": 948,
         "digest": "sha256:342ddde788738b726daf52577c2a67ad255ea907c10514b4989a68775d2be7c3",
         "platform": {
            "architecture": "ppc64le",
            "os": "linux"
         }
      },
      {
         "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
         "size": 948,
         "digest": "sha256:23e1d058ec0a775cb7c803a3acdabcce3c05fd4e0f199e8ffd18e8ff2a6a019a",
         "platform": {
            "architecture": "s390x",
            "os": "linux"
         }
      }
   ]
}

受支持的操作系统仅为Linux（在各自的体系结构上）。

因此您要么必须使用基于Windows的父映像来开发自定义nginx映像，然后将其在Dockerfile中用于上述构建。

这是在Microsoft / windowsservercore：ltsc2016之上构建的示例nginx图像
