为点网（不是点网核心）应用程序创建 Dockerfile

Question

I'm trying to create a Dockerfile for a dot net application (C#).

This application prints a string in the console when I run "OPCConsole.exe" from the terminal.

I am trying to build the Dockerfile in such a way that once the docker run is done this string is printed in the terminal.

My Dockerfile is:

# env .NET on DockerHub
# FROM mcr.microsoft.com/dotnet/sdk:6.0
FROM mcr.microsoft.com/dotnet/framework/sdk:4.8

# copy all files in the folder
COPY . ./ 

# ENTRYPOINT ["./bin/Debug"]
# CMD ["OPCConsole.exe"]
RUN /bin/Debug
RUN OPCConsole.exe

Now I have this error:

failed to solve with frontend dockerfile.v0: failed to create LLB definition: no match for platform in manifest sha256:3b60fb291ae58ea993c257c4da44423605b2d797c935b5d0ce1149ccccc87d6b: not found

Thanks for help!

I suspect your are pulling mcr.microsoft.com/dotnet/framework/sdk:4.8 from a linux machine.

If yes, as explainedhere , those images are for Windows only.

Infact, pulling it from my linux laptot I get:

> docker pull mcr.microsoft.com/dotnet/framework/sdk:4.8

4.8: Pulling from dotnet/framework/sdk
no matching manifest for linux/amd64 in the manifest list entries
