I’m working on my first dockerfile from Visual Studio 2022. This is an .net core 2.1 MVC project. I started with the dockerfile created by VS. The files and folders are created seemingly fine in the container. But I get a runtime error:
Could not find a part of the path ‘/app/Connfolder/Connfile.xml’
Here’s the dockerfile:
FROM mcr.microsoft.com/dotnet/aspnet:2.1 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
FROM mcr.microsoft.com/dotnet/sdk:2.1 AS build
WORKDIR /src
COPY . .
COPY /bin/Release/netcoreapp2.1/Library.dll .
COPY [“List.csproj”, “.”]
RUN dotnet restore “./List.csproj”
COPY . .
WORKDIR “/src/.”
RUN dotnet build “List.csproj” -c Release -o /app/build
FROM build AS publish
RUN dotnet publish “List.csproj” -c Release -o /app/publish /p:UseAppHost=false
FROM base AS final
WORKDIR /app
COPY /Conn/Conn.xml /app/Connfolder/Connfile.xml
COPY --from=publish /app/publish .
ENTRYPOINT [“dotnet”, “List.dll”]
Please advice what’s wrong. Thanks.
