This Redmine 4 plugin stores file attachments on Amazon S3 instead of the local filesystem.
!!! Actually, I don't like this solution, but it works for me and it was fast implementation ...
-> Much more I would appreciate if Redmine switch to Active Storage which is part of Rails and works like a charm for locals storage end even for cloud storages.
clone the plugin into plugins and name it "amazon_s3"
copy the default configuration into your Redmine setup
cp plugins/amazon_s3/config/amazon_s3.example.yml config/amazon_s3.yml
update your dependencies
bundle
delete the .git directory of the plugin and commit it to your favorite version control system
rm -Rf plugins/redmine_s3/.git
