It's for excluding files when building images, right?

Wait, I thought it was about ignoring volumes? Confused!

I agree, B is the correct answer. Makes sense!

I don't think it's about volumes or ports, so I would lean towards option B as well. It just makes sense to exclude files that aren't needed for the image.

I feel like I read something about it being related to the Docker image build process, but I can't recall if it was about excluding files or something else.

I remember practicing a question about Docker files, and I think the .dockerignore helps with optimizing builds by ignoring unnecessary files. Maybe it's option B?

I think the .dockerignore file is meant to exclude certain files from being sent to the Docker daemon, but I'm not completely sure which option that is.
