how to put static resources on my self-built server

I use the docker image on dockerhub to deploy my service. But getting static resource through cdnjs.cloudflare.com is relatively slow for me. So Is there an easy way to put static resources on my self-built server?

atm you could modify the urls here:

pastebin/src/plugins.rs

Line 15 in a8e8476

let base_css_imports = vec![

but it's not configurable from the CLI

Thanks for your help!
