是否有可能在docker容器内使用c#运行dotnet cli命令?

Question

我正在尝试使用c#在docker容器内脚手架一个新的dotnet Web Api项目，但得到一个错误An error occurred trying to start process 'dotnet.exe' with working directory '/app'. No such file or directory.

var process = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "dotnet",
Arguments = "new webapi -n WebApi"            
}

};
process.Start();

下面是Dockerfile

RUN dotnet build "WebApplication1.csproj" -c Release -o /app/build

RUN dotnet publish "WebApplication1.csproj" -c Release -o /app/publish
FROM base 
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "WebApplication1.dll"]

是否有办法在docker容器内引用dotnet.exe ?

Answer 1

原来我使用的是运行时作为基础映像，而不是SDK。这是更新后的Dockerfile。

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /app
EXPOSE 80
EXPOSE 443
COPY . .
RUN dotnet restore "WebApplication1.csproj"
RUN dotnet publish "WebApplication1.csproj" -c Release -o /app/publish
WORKDIR /app/publish
ENTRYPOINT ["dotnet", "WebApplication1.dll"]
