Who has articles on deploying wifi on aruba instants?

Question

System administration

Who has at least the experience of building wifi on aruba? maybe some useful links? or vids? I didn't find anything on the Internet. The scheme is as follows: there is an ubuntu server, it has a hotspot, nat, iptables, dhcp-server, routing will go through it, then control switch. access ports and aruba points in them. I would be grateful for any useful information and links, guides, mana. Thanks
