Docker, Output is hidden

Question

Inside a dockerfile I had:

RUN python3 --version

While I see the command being executed when I build my docker image like this:

docker build -t dn ./

I'm not seeing an output. So I though about changing it to:

RUN echo python3 --version

But that didn't solve my problem, any suggestions?

Note: I don't want all commands to show output in terminal only the ones I specify.

Does the recommendation in [When using BuildKit with Docker, how do I see the output of RUN commands?](https://stackoverflow.com/questions/55756372/when-using-buildkit-with-docker-how-do-i-see-the-output-of-run-commands) (`docker build --progress=plain`) help? — David Maze, May 09 '22 at 11:21

Try setting the environment variable DOCKER_BUILDKIT=0 and then execute the docker build command again. DOCKER_BUILDKIT=0 docker build -t dn ./ as explained here https://makeoptim.com/en/tool/docker-build-not-output

Is there a more clean way of showing output to specific commands only rather than showing for all? – Omer May 09 '22 at 11:19
even though this doesn't answer my question I will accept as workaround.. – Omer May 09 '22 at 15:06
sorry i didn't see the note at the end of the question. – Ben May 10 '22 at 08:31
