In Bazel, you are not supposed to fetch external data during a build action. Instead, we have repository rules and MODULE extensions that are allowed to fetch data from the internet and execute arbitrary code.

This session describes how to implement those rules to access data from authenticated HTTP endpoints making optimal use of Bazel’s downloader, the repository cache, and the new credential helper mechanism in the process. All while saving disk space and time.

You wouldn’t let your friends use wget in a genrule and make the build non-deterministic, right?
