Full Description

rpi-telegraf

Telegraf is an agent for collecting metrics and writing them to InfluxDB or other outputs. This build is for the Raspberry Pi using Alpine Linux base. The Dockerfile is at https://github.com/bradsjm/Dockerfiles/tree/master/rpi-telegraf

Telegraf is an open source agent written in Go for collecting metrics and data on the system it's running on or from other services. Telegraf writes data it collects to InfluxDB in the correct format.

Using the default configuration

The default configuration requires a running InfluxDB instance as an output plugin. Ensure that InfluxDB is running on port 8086 before starting the Telegraf container.

Minimal example to start an InfluxDB container:

$ docker run -d --name influxdb -p 8083:8083 -p 8086:8086 bradsjm/rpi-influxdb

Starting Telegraf using the default config, which connects to InfluxDB at http://localhost:8086/:

$ docker run --net=container:influxdb bradsjm/rpi-telegraf

Using a custom config file

First, generate a sample configuration and save it as telegraf.conf on the host:

$ docker run --rm bradsjm/rpi-telegraf -sample-config > telegraf.conf

Once you've customized telegraf.conf, you can run the Telegraf container with it mounted in the expected location:

$ docker run -v $PWD/telegraf.conf:/etc/telegraf/telegraf.conf:ro bradsjm/rpi-telegraf

Modify $PWD to the directory where you want to store the configuration file.
