[Feature request] Allow UNIX socket support for InfluxDB

[simonvanderveldt]

InfluxDB supports exposing its HTTP service over a UNIX domain socket, see https://docs.influxdata.com/influxdb/v1.3/administration/config/#unix-socket-enabled-false

It would be nice if grafana would support this. It would allow running Grafana against a local InfluxDB server without opening up InfluxDB to the outside.
Also it would allow Grafana to be used in a container without opening InfluxDB to the outside. And, even better, Grafana wouldn't need to know the IP address of the host it's running in because the socket can be mounted as a volume.

Seems quite useful feature. I will try to submit PR for this.
Thanks @simonvanderveldt

Any update on this?

let me take another look and post my findings.

Any update @akshaychhajed?

According to Go docs net supports Unix sockets out of box so it should only be matter of updating settings validation to allow unix:// and properly configuring Dial().

Dial("unix", "/run/influxdb/influxdb.sock")

It would allow Grafana to be used in a container without opening InfluxDB to the outside.

Without this feature I think this is still possible.
I believe you can accomplish easiest by using a docker-compose file.

Create a influxdb and grafana service definitions. For the influxdb entry use the expose attribute to expose the api server's port (e.g. 8086) to the other services (in this case grafana).

Then in your Grafana's data source the URL would be http://influxdb:8086 where the word influxdb equates to the name of your influxdb service defined in the docker-compose file.

@torkelo @bergquist no one is assigned to this issue/feature. Can one of you review or assign reviewer? (PR #15747 )

thanks @SamuelToh . That would work too.
This feature would not be limited to influxdb though.
It can support any datasource serving http over unix-socket.
It would provide more flexibility.

Looking forward to this feature 👍

the current version of influxdb is 2.0.something, and there does not seem to be an option to use unix sockets, or at least i could not find it. is anyone using unix sockets with influx2?
