I'm trying to start the kibana service on a CentOS 7 system but the ${HOSTNAME} environment variable isn't being recognized by the service:

server.name: {HOSTNAME} server.host: {HOSTNAME}

When I start the service via systemctl, the service fails and the following lines appears in journalctl:

kibana[23654]: FATAL CLI ERROR Error: Unknown environment variable referenced in conf  
ig : HOSTNAME

Is there an issue with how I am entering the data in the yml file or something I need to do on my system?

Could you share the relevant portion of your kibana.yml config file?
