Thanks for the reply, @bluepuma77.
No, none of them are. That’s why I asked specifically about the dynamic configuration file provider.
If I use a separate file for each service, then if I need to tweak the configuration, I’d have to update hundreds of files, right?
Templating seems like the best option from a maintenance standpoint, but I still don’t understand how to add/remove services (just different domains really) in that scenario in an automated/dynamic way.
I guess my situation is similar to this one, except that I would need to be able to update many different domains dynamically. As I understand, environment variables are manually/statically configured, right?
