pitrou opened a new issue, #43969: URL: https://github.com/apache/arrow/issues/43969
### Describe the enhancement requested The `.dockerignore` file governs which files are sent in the "build context" of a Docker image, which in turn [impacts Docker caching](https://docs.docker.com/build/cache/optimize/). Our `.dockerignore` file seems to have a lot of stale entries. Also, some of them seem dubious (why include `dev/archery/setup.py` if you don't include Archery's source tree, for example?). ### Component(s) Continuous Integration, Developer Tools -- This is an automated message from the Apache Git Service.
