 ## all containers running but "Zabbix server" host item not reachable in UI
+
 Thats because the default "Zabbix server" item in Zabbix is looking for "localhost" which isn't working in containers as it's normal.
 So to solve that problem you can:
+
 - simple change "localhost" to "zabbix-agent" which points to the, hopefully also started, Zabbix Agent container.
-- 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.
