Docker-jitsi-meet config with an external working coturn server

Dear friends,

to work with my self-hosted jitsi instances at home from the restricted network at work i set up a little debian coturn virtual machine from hetzner. Configuring is a little tricky but first of all now it works with nextcloud talk and matrix voip on the same docker host in my private network. Jitsi of course needs the TURN integration to work properly from restricted networks.

Jitsi instances ( using 5870-stable ) works without any problems from unrestricted networks but whats the simplest way to integrate permanent my coturn server?

Thanks for any hints in advance!
