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.

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
