I am looking to install Grafana and InfluxDB on hass.io.
I know there is an all-in-one approach as documented here: https://home-assistant.io/blog/2017/04/25/influxdb-grafana-docker/
But I would prefer to install using the official dockerhub images for the 3rd part components:
These are updated more regularly than the AIO image, and also built on more space efficient base images.
I am comfortable to install via either approach directly in docker, but I would prefer to create hass.io addons for this.
So back to my original question: is there a correct way to use a pre-existing dockerhub image for a hass.io addon?
(as opposed to including a dockerfile in the addon to build an image)
