Because there are so many possible configuration combinations there are also a lot of docker-compose templates. The highlight here is on templates! They simply aren't supposed to be `docker-compose up -d -f docker-compose_v3_ubuntu_pgsql_latest.yaml`. You should instead copy the one you like and then tailor it to your needs.

```
Every time a container is created it gets a new id/hostname unless you set the `hostname: zabbix-agent` or add `ZBX_HOSTNAME=zabbix-agent` to the env variables. Then you can create an Zabbix host with `zabbix-agent` as item.
