azure - 在 docker 文件内发布时出现容器错误

Question

我正在使用 ubuntu-latest 代理在 Azure Devops 中使用 .NET7- 构建 docker 镜像。之前的所有层直到发布都成功。但是，在发布 dll 时，我收到以下错误。

/root/.nuget/packages/microsoft.net.build.containers/0.4.0/build/Microsoft.NET.Build.Containers.targets(195,5): error CONTAINER1012: The local daem on is not available, but pushing to a local daemon was requested. Please start the daemon and try again.

这是 docker 文件

FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
WORKDIR /source
COPY ["src/TestAPI/TestAPI.csproj", "src/TestAPI/"]
RUN dotnet restore "src/TestAPI/TestAPI.csproj"
COPY . .
WORKDIR "/source/src/TestAPI"
RUN dotnet build "TestAPI.csproj" -c Release

FROM build AS publish
WORKDIR /source/src/TestAPI
RUN dotnet publish "TestAPI.csproj" -c Release -o /app/publish

这是来自 Azure Devops 的错误

MSBuild version 17.6.1+8ffc3fe3d for .NET Determining projects to restore... All projects are up-to-date for restore. TestAPI -> /source/src/TestAPI/bin/Release/net7.0/TestAPI.dll TestAPI -> /app/publish/ Building image 'testwebapi' with tags 1.1.0 on top of base image mcr.microsoft.com:443/dotnet/aspnet:7.0 /root/.nuget/packages/microsoft.net.build.containers/0.4.0/build/Microsoft.NET.Build.Containers.targets(195,5): error CONTAINER1012: The local daemon is not available, but pushing to a local daemon was requested.

            command: build
            Dockerfile: $(dockerfilePath)
            tags: $(tag)

Answer 1

我可以解决这个问题。这个问题是我们正在尝试测试 .NET7 中引入的新功能，我们可以在没有 docker 文件的情况下构建 docker 镜像，该功能已启用，而且我还有用于在 Azure devops 中构建的 docker 文件，但在某个地方存在互操作问题。我已在解决方案级别的 Directory.build.props 文件中更改了此设置。

 <PropertyGroup>
      <!--<PublishProfile>DefaultContainer</PublishProfile>
      <ContainerImageTags>1.1.0</ContainerImageTags>-->
    </PropertyGroup>

评论了这两个，它开始工作。
