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 Dockerfile:
# 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?
