我有一个解决方案，其中包含作为类库的 protobuf 定义文件，以及引用 protobuf 定义文件的 gRPC 服务。它与根文件夹中的解决方案文件捆绑在一起。
如果我在 Windows 机器上构建项目，则没有问题：
$ dotnet build "GrpcService/GrpcService.csproj" -c Release -o build
MSBuild version 17.5.0+6f08c67f3 for .NET
Determining projects to restore...
Restored ...\DockerTest\GrpcService\GrpcService.csproj (in 131 ms).
GrpcService -> ...\DockerTest\build\GrpcService.dll
Build succeeded.
0 Warning(s)
0 Error(s)
Time Elapsed 00:00:01.14
构建后，我可以使用命令
dotnet .\build\GrpcService.dll之后，我尝试在 Docker 容器内构建我的解决方案。我创建了一个如下所示的 Dockerfile：
FROM mcr.microsoft.com/dotnet/sdk:7.0.203-alpine3.17 AS build
WORKDIR /src
COPY DockerTest.sln ./
COPY Test.Grpc/*.csproj ./Test.Grpc/
COPY GrpcService/*.csproj ./GrpcService/
RUN dotnet restore
COPY . .
RUN dotnet build "GrpcService/GrpcService.csproj" -c Release -o /app/publish/backend
当我尝试在 Docker 容器内构建项目时，构建失败，因为原型构建器找不到
/src/GrpcService/GrpcService.csproj$ docker build .

但是，如果我从 Dockerfile 中删除最后一条指令，创建一个容器并转储容器中的内容以查看其外观，该文件显然就在那里。
docker export -o dump.tar [container-id]那么到底出了什么问题？
我有一段时间遇到同样的问题，这似乎是 GRPC 方面的一个已知问题。这是关于它的Github 讨论。它提到了一种解决方法，即安装自定义
glibc
