How to run the docker image? (getting .NET framework mistmatch)

[gjermystreeva]

Hi @rogeralsing - I'd like to trial using the tracelens project.

Unfortunately I've tried running up the amd64 docker image and currently am getting error below.

Am I missing something / using the wrong version? Is there a different image I should be referencing.

Note currently I'm using docker.io/rogeralsing/tracelens:amd64

Thanks for any assistance.

Hey @gjermystreeva . let me get back to you on this tomorrow. I've been fiddling with multi-target builds so I think that should start working soon. e.g. you don't have to choose a platform.

Ok thanks, but just to confirm all I'm initially trying to do is run up the docker image docker.io/rogeralsing/tracelens:amd64. I did try installing missing .net within it but then on running seemed to be looking for a localhost postgres endpoint. If there is a different image to try I will give better feedback.

Image seems to be using ASP.NET 7 as base, although 8.0 Preview 4 seems to be required. As a workaround I built my own image using 8.0 Preview 4 as base and just copied the app from tracelens image

Here's the Dockerfile if anyone's interested.

FROM mcr.microsoft.com/dotnet/aspnet:8.0.0-preview.4 AS base
WORKDIR /app
EXPOSE 5001
EXPOSE 4317

FROM docker.io/rogeralsing/tracelens:amd64 AS build
WORKDIR /app

FROM base AS final
ENV ASPNETCORE_URLS=http://*:5001;http://*:4317
WORKDIR /app
COPY --from=build /app/ .
ENTRYPOINT ["dotnet", "TraceLens.Server.dll"]

I'm however now also stuck on the same Postgres stage as @gjermystreeva. Any documentation on how to set this up?

I'm a bit stuck upgrading everything here. I have managed to get a cross platform build, so you will be able to just run :latest tag instead of picking a platform.

But while upgrading, there are some code issues I need to resolve first. stay tuned

[rogeralsing]

I´ve published a new docker compose file and fresh builds for the cross platform support.
