I just got a MacBook from work and I am using it to build docker images. Usually, the docker build shows the full log (i.e. ls -la
showing the cwd). Thats at least what I'm used to from my linux machine.
On the macbook however, it only shows a brief overview: (actual console output)

=> => naming to docker.io/library/customsql
Steps 7 and 15 are supposed to show me the results, but this is just omitted. (I know, its the cached result, but it didn't show up, when I changed the Dockerfile and rebuild the layer as well).
setting --progress=plain
didn't do any good. In fact it just changed the color from purple to white (HideThePainHarold.jpg).
Any help will be greatly appreciated.
Found the answer myself: apparently Docker build on OSX is automatically configured to use BuildKit, which disguises a lot of the default debug output.
I removed the option {"buildkit": true}
from daemon.json
config file and it works.
