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 应用程序。我在 Windows PC 上，但是 visual studio 部署环境设置为 Linux 和 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 (运行ning) 中。但是，在尝试将其发布到 Docker Hub 时，出现以下错误。

你能帮我看看我的 PC 上缺少哪个部分吗（它是 azure windows 10 VM）？

注意： 我也可以运行 linux 容器，没有任何问题。另外 Ubuntu 20 是从 Windows 商店安装的。

Answer 1

我有同样的问题，我可以通过使用以下命令将 docker 上下文切换回默认值（它被设置为桌面-linux）来解决：

docker context use default

Answer 2

在文件中

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

更改桌面-linux

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

currentContext 有 desktop-linux，我只是放了“default”

Answer 3

为 Windows 3.4.0 恢复到 Docker 对我有用。

在此处下载： https://docs.docker.com/docker-for-windows/release-notes/#docker-desktop-340

这里讨论了这个错误： https://github.com/docker/for-win/issues/11530 https://developercommunity.visualstudio.com/t/unable-to-publish-to-acr-running-the-dockerexe-tag/1464650 https://developercommunity.visualstudio.com/t/current-context-desktop-linux-is-not-found-on-the/1463380
