Deploy sdelements chat app in 2.0

As like the documentation in version 1.6 I want to deploy chat application in version 2.0 from UI itlself. I am new to rancher and figured out services in 1.6 is eqivalent to workloads in 2.0. So my question is now in 2.0 how can I link the two workloads database and web similar like in version 1.6 and with the loadbalancer expose it to my localhost browser to access the chat app. Has anyone done this from UI please let me know.

Thank you
