hey nice work. I did the same thing but for Brightbox: https://github.com/brightbox/deploy-jitsi
realised I've not licensed it properly though! will sort that out tomorrow.
blogged about it here: https://www.brightbox.com/blog/2020/03/30/how-to-install-jit...
took me a while to sort out the fqdn config change, did you get that working?
