I am using the latest version of Docker Desktop on Windows (Docker Engine version v19.03.13).
After the last update, the output of
docker build . has changed! It is now harder to debug what is going on.
Here is my
# set base image as the dotnet 3.1 SDK. FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env # set the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD # instructions that follows the WORKDIR instruction. WORKDIR /app # debug purposes - see where we are RUN pwd # our current working directory within the container is /app # we now copy all the files (from local machine) to /app (in the container). COPY . ./ # debug purposes - list files in current folder RUN ls -la # run unit tests within the solution. RUN dotnet test Phoneden.sln # again, on the container (we are in /app folder) # we now publish the project into a folder called 'out'. RUN dotnet publish Phoneden.Web/Phoneden.Web.csproj -c Release -o out # debug purposes - list files in current folder RUN ls -la # set base image as the dotnet 3.1 runtime. FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS runtime # telling the application what port to run on. ENV ASPNETCORE_URLS=http://*:5005 # set the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD # instructions that follows the WORKDIR instruction. WORKDIR /app # copy the contents of /app/out in the `build-env` and paste it in the # `/app` directory of the new runtime container. COPY --from=build-env /app/Phoneden.Web/out . # set the entry point into the application. ENTRYPOINT ["dotnet", "Phoneden.Web.dll", "-seed"]
When I run
docker build --no-cache . I get the following:
jwan@home-desktop MSYS /c/code/phoneden (upgrade/net-3.1) $ docker build --no-cache .

As you can see, it is not listing the result of the debug commands I added.
How can I get the output to be verbose like it was before the update?
