Docker cli use older logging?

Question

I just installed docker desktop on my windows box, but I uses the new output style, i'd like to switch back to the old style, having trouble finding the exact command or profile part to change.

What I have

docker build .

The new logging style comes from the BuildKit features.

You can disable this in the Docker Desktop GUI:

select the Docker Engine tab
set "features"{ "buildkit" : false }

Then if you want to use the logging features again, you can run with DOCKER_BUILDKIT=1. I believe you can run with DOCKER_BUILDKIT=0 if you want to selectively disable but haven't tested that yet.

Of course, be aware that you'll lose out on the following features that BuildKit adds to Docker:

Docker images created with BuildKit can be pushed to Docker Hub just like Docker images created with legacy build
the Dockerfile format that works on legacy build will also work with BuildKit builds
The new --secret command line option allows the user to pass secret information for building new images with a specified Dockerfile
