Creating an influxdb database

I’ve installed on my Synology nas Docker and within Docker I’ve installed the container ‘monitoringartist-grafana-xx12’ this gives me Grafana with all plugins pre installed.
Within my browser i can access Grafana and within Configuration chosen Influxdb. This brings up the panel ‘Data Sources / InfluxDB-1’ ?? and now i’m a bit stuck
(the image shows the panel)
I’m assuming the 8086 within the URL setting is fixed, it is what was originally shown but without my IP.
Within influxdb details what do i enter as the database detail ?
Is there anything else i should be entering or changing within this panel
Is here anything else i should have done ?
Yes i am a complete novice regards Grafana and influxdb
Thanks for any help you can give
