Which file upload service to use in Docker?

Question

Data storage

What to take to upload files to wrap in Docker and run on a subdomain of the site? I'm tired of writing my upload every time. If there is integration with Keycloak, then it is generally ideal. Authorization on the site through it just.
Surely someone here uses similar solutions. Share your experience, please. The question is not "how to use", but "with what less hemorrhoids."
I am not considering third-party file storage services yet. I want my own, so as not to depend))
