Docker Hub
https://hub.docker.com/r/arm32v7/influxdb/#!08.01.2010 · The builds were very bare-bones, containing the influx and influxd binaries without any default configuration or helper scripts. By default, the influxd process stored data under /root/.influxdbv2. Starting with v2.0.4, we've restored our DockerHub build. This build defaults to storing data in /var/lib/influxdb2.
