在 Docker Hub 上发布 .Net Core Web 应用程序时出错

Question

我正在学习 docker 和容器。我正在尝试通过 Visual Studio 2019 在 Docker Hub 上发布我的 .Net Core 3.1 Web App。我在 Windows PC 上，但 Visual Studio 部署环境设置为 Linux，Docker 也设置为 Linux。我也安装了 WSL2（Linux 2 的 Windows 子系统）。此外，Web 应用程序运行良好，同时我可以看到容器和图像已成功创建到 Docker 仪表板（正在运行）中。但是，在尝试将其发布到 Docker Hub 时，出现以下错误。

你能帮我找出我的电脑（它是 azure windows 10 VM）上缺少哪个部分吗？

注意：我也可以毫无问题地运行 linux 容器。Ubuntu 20 也是从 Windows 商店安装的。

在文件中

file:///C:/Users/UserName/AppData/Local/Temp/c69e796a148440f18675b80111e06796/config.json

换桌面-linux

{
  "auths": {},
  "credsStore": "desktop",
  "currentContext": "default",
  "stackOrchestrator": "swarm",
  "HttpHeaders": {
    "X-Meta-Source-Client": "vs/web/publish"
  }
}

currentContext 有桌面 Linux，我只是把“默认”
