EYou can't configure ZITADEL directly in the compose file like this. You have to mount the ZITADEL config to the container. See an example for this (also with a custom domain) here https://zitadel.com/docs/self-hosting/deploy/loadbalancing-example
With this example configuration, you create a near production environment for ZITADEL with Docker Compose.
FYou can extend the env from the zitadel container directly
like ZITADEL_EXTERNALDOMAIN=auth...
On a second note, the TLS setting you provide is only meant to be used if you use TLS from your proxy to ZITADEL or directly to ZITADEL
Most times you use the TLS Mode External its being used as disabled (if enabled you need to provide the zert material)
