无法构建：获取https://registry-1.docker.io/v2/microsoft/aspnetcore/manifests/1.1：未授权：用户名或密码不正确

Question

我的aspnetcore docker项目构建，但是当我单击Docker按钮（或按F5）运行时，我得到了

Severity    Code    Description Project File    Line    Suppression State
Error   MSB4018 The "PrepareForLaunch" task failed unexpectedly.
Microsoft.DotNet.Docker.CommandLineClientException: Creating network "dockercompose1627893588_default" with the default driver

我有C：使用Docker设置共享。我正在使用linux容器

Dockerfile是

FROM microsoft/aspnetcore:1.1
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "PsWebApi.dll"]

我已升级到最新的nuget包。

Answer 1

用于登录dockerhub的user id和相应的email在这种情况下实际上是两个不同的东西。

一个人需要id，用户名，而不是email来获得images。

---

解决

通过做一个改变两者之间

> docker logout

然后在命令行上

> docker login

并使用您的id登录。

请注意，在您使用电子邮件登录后，可以在docker站点上找到id。

系统将提示您输入凭据。同样，对于该用户名，请不要使用电子邮件地址。

Answer 2

我在最新的ASP.NET Core模板中也遇到了同样的问题。以下修复对我有用。

• 打开Package Manager Console窗口。
• 运行命令docker logout。

然后再次运行/调试（F5）应用程序。

一方面需要注意的是，您需要在Docker中切换到Windows容器。否则你会看到另一个错误：image operating system "windows" cannot be used on this platform。
