Config docker server: zabbix.conf.d or env variables?

[ZabbixSeeker]

What's the best practice to ship configuration with zabbix docker -- and to store host-persistent zabbix configuration for a docker project?

mount a file in /etc/zabbix-server/zabbix.conf.d/, or include a file with env variables in the docker project file?

seems like /etc/zabbix-server/zabbix.conf.d/ isn't enabled by default - so that cannot be best practice.

I would provide environment variables in a Docker compose.
Don't know, if this is "best" practice.
