 - or, arguably better!, you remove the Zabbix Agent template from "Zabbix server" (while leaving the Zabbix server templates!) and create a new host "Zabbix agent" which you point to the zabbix-agent container and link the template there.
 
 ## why are there so many containers with Docker Compose?
-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. So for example if you choose Postgres as your DB copy the pgsql_latest to docker-compose.yml and just keep the services you need.

+## The agent container states "host [xxx] not found"

+```log
+ 22264:20210318:123205.124 no active checks on server [zabbix-server:10051]: host [722372e65167] not found
+```
+
+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.
