Quick and Dirty build of a Telegraf-based Docker Image to store raw data from MQTT into InfluxDB.
This repository will become much simpler when this pull request is merged into Telegraf, until then:

Build

docker build -t dersimn/mqtt2influxdb .

(or use the pre-build image on Docker Hub)

Run

Configure environment variables according to your needs:

MQTT_HOST="mqtt"
MQTT_PORT="1883"
INFLUXDB_URL="http://influxdb:8086"
INFLUXDB_DB_NAME="raw_mqtt"
INFLUXDB_MEASUREMENT_NAME="string_data"

Example:

docker run -d --restart=always --name=mqtt2influxdb -e "MQTT_HOST=10.1.1.50" -e "INFLUXDB_URL=http://10.1.1.50:8086" dersimn/mqtt2influxdb
