Collabora docker - set domain name of container

Hello,

I installed docker and the Collabora image.
But I have some problems with SSL. If I go to https://office-collabora/hosting/discovery this is the xml what I get:




(extract).

as you can imagine, I can’t get a Let’s encrypt cert for this IP. How can I change this IP from 192.168.1.23 to the required office.mytld.com?

Regards,

Max
