Alpine 3.10 image's shell doesn't know globstar. After reading some article and feeds written by GNU and stackoverflow, I replace ** with {*, */*, */*/*, */*/*/*, */*/*/*/*, */*/*/*/*/*} in CI scripts to meet the temporary requirement sadly :/

Why would GNU write anything about this? This thing about alpine is, that its non-gnu.

Firstly alpine doesn't have GNU utils. That's its thing.

Secondly it generally is bad practices to blindly use the globstar like that. (and the workaround also isn't great)

If you want a list of files that match a certain pattern use the find command.
