Installation

Pre-requisites

A Raspberry Pi with a serial OBD reader, or with a Bluetooth reader connected to /dev/rfcomm0. See these instructions for help.

Manual Installation on Kubernetes

kubectly apply -f https://raw.githubusercontent.com/zaneclaes/tiny-cluster/master/kubernetes/obd-monitor.yaml

And then label the nodes which you wish to deploy on (replacing [NODE_NAME] with your node):

kubectl label nodes [NODE_NAME] tiny-cluster/node-pi-obd-monitor=true

Run with Docker

Assuming the device resides at /dev/rfcomm0, the command will be something like this:

docker run --rm --name obd-monitor --mount "type=bind,source=/dev/rfcomm0,target=/dev/rfcomm0" --privileged=true inzania/node-pi-obd-monitor:latest
