You could use SSHFS or NFS to do this:

For relying on this in production, NFS would be better than SSHFS. That said, unless you’re very experienced with server administration, I actually don’t recommend either. You’re much better off sticking with technologies you understand and are familiar with debugging when things go wrong. For example, use a web server running on the central server and serve files to your other servers over HTTP/HTTPS.

Thanks @jsamuel,

I thought about micro-services, but at present it’s just not feasible for me to do it due to the amount of work this would require. Some of the resources include javascript files, which don’t like sharing over the http/s.

@sebssd That makes sense, there’s always the time constraint.
