How do I set-up my PR4100 to self-host my website?

Does anyone know How do I set-up my PR4100 to self-host my website?

I have docker installed and on OS5 and I wanted to follow a guide like this. But I wanted to know if there was a PR4100 specific guides around.

I’m going to use Cloudflare, so it is less dangerous as the IP address is not exposed.

The main assistance I need is installing ubuntu server 20.04. I want to retain the My Cloud OS 5 and have an ubuntu server running on a partition or something. So how do I set this up?
