Telegraf docker image for use with the Raspberry Pi.
Note - no Telegraf configuration is supplied, this must be mounted into the container.
First generate a configuration file. This example collects CPU/memory stats and exposes them for Prometheus to collect.
docker run --rm swestcott/rpi-telegraf telegraf --input-filter cpu:mem: --output-filter prometheus_client config > telegraf.conf
Then mount telegraf.conf into the container
docker run --rm --publish 9126:9126 --volume telegraf.conf:/etc/telegraf/telegraf.conf swestcott/pi3-telegraf:latest
curl -s http://localhost:9126/metrics
