deploy .net 6 mvc project to app engine flex evn-CodePudding

ı wanna deploy a project to google cloud app engine but encountered a problem.

First, I created a folder in app engine ssh and created a net6 project in this folder, then "dotnet restore" this project. I restored it with code. Then I published it with the code "dotnet publish -c Release". Then I added the Dockerfile and app.yaml files that I showed into the publish file. Also, my launchSettings.json file is as follows. Although I do all these configurations and run the "gcloud app deploy" code under the publish folder, I get the log image as below and after saying "gcloud app browse" I get the "502 Bad Gateway" nginx error on the page I go to. What is the reason of this.

This is how I modified the dockerfile. The application worked. As far as I understand, the port was not working because I did not export it.

FROM mcr.microsoft.com/dotnet/aspnet:6.0
ADD / /app
EXPOSE 8080
ENV ASPNETCORE_URLS=http://*:8080
WORKDIR /app
ENTRYPOINT [ "dotnet", "giveawayproject.dll"]
