How to make this work on raspian?

[TinajaLabs]

Installing graphite/grafana on a raspberry pi that's running Raspian stretch. I keep getting an error about:

fatal: [tinaja-gr]: FAILED! => {"changed": false, "msg": "Could not find the requested service graphite-api: host"}

I suppose I need to modify this role to include tasks for systemd, right?

I figure I need to create a template for the systemd graphite-api.service, change the configure.yml file to include a systemd started/enable section, add a new handler?

Anything else? Can someone outline the tasks, please?

Thank you,
Chris.
