Environment Variables

Environment Variable	Description
`DOCKER_GUID`	Group ID number for the `docker` user group
`DOCKER_INFLUXDB_INIT_ORG`	Organization name for InfluxDB
`INFLUX_WRITE_TOKEN`	InfluxDB write token
`INFLUX_HOST`	Hostname or IP address of the InfluxDB instance
`LOKI_HOST`	Hostname or IP address of the Loki instance

Setup

Set the DOCKER_GUID so the container has permission to access the socket. This ensures that the telegraf container will have read access on the Docker socket.

export DOCKER_GUID=$(getent group docker | awk -F ':' '{print $3}')
