# Nomadic Zabbix Server v6.2
I have been using [Docker-Compose to deploy the Zabbix Server environment](https://github.com/mpolinowski/zabbix-server-compose). But I would like to move this into my Nomad/Consul cluster. Following is the "translation" of the [docker-compose file](https://github.com/mpolinowski/zabbix-server-compose/blob/master/docker-compose.yml) into a Nomad job.
> There is still __one shortcut__ in here - I have not yet setup Consul to help me connecting all my service (_TODO_). So I am running this with `network_mode=host` and connect all components over _127.0.0.1_.
