docker - 无法构建 : Get 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

我确实有 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

user id和对应的email用来登录dockerhub的其实是两个不同的东西在这种情况下。

需要id，用户名，而不是email来获取images。

解决

通过在两者之间进行切换

> docker 注销

然后在命令行上

> docker 登录

并使用您的 id 登录。

请注意，id 可以在您使用电子邮件登录后在 docker 网站上找到。

系统将提示您输入凭据。同样，对于该用户名，不要使用电子邮件地址。
