Possible .dockerignore misconfiguration

[tomokinakamaru]

(I am posting this here because I was not sure if it is actually a bug or not.)

As part of my research, I am analyzing how developers configure .dockerignore in popular repositories.

During my analysis, I noticed that /.dockerignore might have been written under the assumption that .dockerignore and .gitignore follow the same pattern semantics, while they actually differ.¹ In particular, the following pattern drew my attention:

cards-database/.dockerignore

Line 8 in 70c9252

.DS_Store

According to Docker's specification, this pattern matches .DS_Store only in the top-level directory. (To ignore .DS_Store in any directory, the .dockerignore file needs to list **/.DS_Store)

Was this pattern written intentionally? If not, I'd be happy to submit a pull request to adjust it.

And if possible, could one of the maintainers tell me whether he/she were aware of the difference between .dockerignore and .gitignore? (I would like to know whether the differences are generally well recognized, or if they tend to slip developers' minds.)

Thank you for maintaining this repository!

It is completly because I though .gitignore & .dockerignore work the same, you can create a PR if you want to !
