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 .

Answer 1

The new logging style comes from the BuildKit features.

You can disable this in the Docker Desktop GUI:

1. select the Docker Engine tab
2. 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
