potiuk opened a new pull request #15593: URL: https://github.com/apache/airflow/pull/15593
When building images for production we are using docker-context-files where we build packages to install. However if those context files are not cleaned up, they unnecessary increase size and time needed to build image and they invalidate the COPY . layer of the image. This PR checks if docker-context-files folder contains just readme when Breeze build-image command is run (for cases where images are not built from docker-context-files). Inversely it also checks that there are some files in case the image is built with --install-from-docker-context-files switch. This PR also ads a --cleanup-docker-context-files switch to clean-up the folder automatically. The error mesages also help the user instructing the user what to do. <!-- Thank you for contributing!
