Raspberry Pi (ARM 32bit) compatible Docker base image with InfluxDB, an open source database written in Go specifically to handle time series data with high availability and high performance requirements.

Running your InfluxDB image

Start your image binding the external port 8086 of your containers:

docker run -d -p 8086:8086 sumglobal/rpi-influxdb

Docker containers are easy to delete. If you are serious about keeping InfluxDB data persistently, then consider adding a volume mapping to the containers /data folder:

docker run -d --volume=/var/influxdb:/data -p 8086:8086 sumglobal/rpi-influxdb

Configuring your InfluxDB

You can use the RESTful API to talk to InfluxDB on port 8086. Use the new influx cli tool to configure the database. While the container is running, you launch the tool with the following command:

docker exec -it <influxdb-container-name> /usr/bin/influx

which will open up the influx shell

Initially create Database

Use -e PRE_CREATE_DB="db1;db2;db3" to create database named "db1", "db2", and "db3" on the first time the container starts automatically. Each database name is separated by ;. For example:

docker run -d -p 8086:8086 -e ADMIN_USER="root" -e INFLUXDB_INIT_PWD="somepassword" -e PRE_CREATE_DB="db1;db2;db3" sumglobal/rpi-influxdb:latest

Alternatively, create a database and user with the InfluxDB shell:

  > CREATE DATABASE db1
  > SHOW DATABASES
  name: databases
  ---------------
  name
  db1
  > USE db1
  > CREATE USER root WITH PASSWORD 'somepassword' WITH ALL PRIVILEGES
  > GRANT ALL PRIVILEGES ON db1 TO root
  > SHOW USERS
  user  admin
  root  true
