How to exclude files with specific extensions from deployment?

[Troy]

In my article content/chapter-1/ there are three files, e.g. file.png, file.txt and file.mp3.

In my index.md there is only a link to file.png. That’s why I want only file.png to be deployed. How can I achieve this?

I just found the solution in the docs:

[deployment]
[[deployment.targets]]
include = "**.html" # would only include files with ".html" suffix
exclude = "**.{jpg, png}" # would exclude files with ".jpg" or ".png" suffix
