Hello.
The command "docker build . -t letskube:local" terminates with:

=> ERROR [build-env 6/6] RUN dotnet publish -c Release -o output 11.4s

This was useful: https://stackoverflow.com/questions/60746280/building-dockerfile-in-asp-net-core-project-fails-when-running-dotnet-publish-c

I solved by creating a new clone from github and launching "docker build" without having firstly executed "dotnet run"

Also, works once you add ".dockerignore" file in the root directory with the content:

bin/
obj/
out/

then running docker build . -t [ACR-NAME]:[TAG] worked for me :)
