Docker Image with InfluxDB, Grafana and Telegraf

The purpose of this docker image is to provide an image for arm64v8 (Raspberry Pi).

Description	Value
OS	arm32v7/arm64v8
InfluxDB	1.8.10
Grafana	9.3.6
Telegraf	1.25.1

Notes

This is a fork of the repository created by Daniel Gomes. As the last image was over 3 years old and uses 'ancient' versions of InfluxDB, Grafana and Telegraf I decided to take a shot and see if I could get this to more recent versions and still keep it working. And meanwhile learning a bit of creating/maintaining/modifying docker-images.

As to keep it working I might do this in small steps.

As I have only a Raspberry Pi I can only test the image on arm32v7 and arm64v8 after upgrading the Raspberry Pi OS to a 64bits OS.

Starting with Grafana version 8.5.0 I removed arm32v7-support as Grafana wouldn't work in my envioronment and I have unfortunately too less time to figure out why it won't work.

Quick Start

Raspberry Pi (arm32v7/arm64v8)

Start the container by running the following command:

docker run -d \
  --name influxdb-grafana \
  --restart unless-stopped \
  -p 3003:3003 \
  -p 8086:8086 \
  -v /path/for/influxdb_data:/var/lib/influxdb \
  -v /path/for/influxdb_log:/var/log/influxdb \
  -v /path/for/grafana_data:/var/lib/grafana \
  -v /path/for/grafana_log:/var/log/grafana \
  -v /path/for/telegraf_log:/var/log/telegraf \ 
  -e "GF_SECURITY_ADMIN_USER=<YOU_USERNAME_HERE>" \
  -e "GF_SECURITY_ADMIN_PASSWORD=<YOU_PASSWORD_HERE>" \
  -e "TZ=<YOUR_LOCAL_TIMEZONE_HERE>"
  pluim003/influxdb-grafana-telegraf:latest

Note: I added a bunch of extra volumes as I like to be able to view stuff directly on my Raspberry Pi. Feel free to modify the docker-run-command to your needs.

To stop the container launch:

docker stop influxdb-grafana

To start the container again launch:

docker start influxdb-grafana

To backup your Docker-volumes you can use the following script:

#!/bin/bash

CONTAINER=influxdb-grafana
RUNNING_CONTAINER=$(docker container ls -q --filter name=${CONTAINER}*)
CONTAINER_VOL1=/var/lib/grafana
CONTAINER_VOL2=/var/lib/influxdb
CONTAINER_VOL3=
BACKUP_DIR=<YOUR_BACKUP_DIRECTORY_HERE>/${CONTAINER}
TODAY=$(date +"%Y%m%d_%H%M")

if [ ! -d "${BACKUP_DIR}" ] ; then
   mkdir ${BACKUP_DIR}
fi

docker pause ${RUNNING_CONTAINER}

docker run --rm  --volumes-from ${CONTAINER} -v ${BACKUP_DIR}:/backup busybox tar cvpfz /backup/${CONTAINER}cfg_${TODAY}.tgz ${CONTAINER_VOL1} ${CONTAINER_VOL2} ${CONTAINER_VOL3}

docker unpause ${RUNNING_CONTAINER}

# check and delete backupfiles older dan 7 dagen

find ${BACKUP_DIR}/${CONTAINER}cfg*  -mtime +7 -exec ls -ltr  {} \;
find ${BACKUP_DIR}/${CONTAINER}cfg*.tgz -mtime +7 -exec rm {} \;
find ${BACKUP_DIR}/${CONTAINER}cfg*  -mtime +7 -exec ls -ltr  {} \;

Mapped Ports

Host	Container	Service
3003	3003	grafana
8086	8086	influxdb

SSH

docker exec -it influxdb-grafana bash

Grafana

Open http://localhost:3003

Username: <User defined in Environment Variable>
Password: <Password defined in Environment Variable>

Add data source on Grafana

1. Using the wizard click on Add data source
2. Choose a name for the source and flag it as Default
3. Choose InfluxDB as type
4. Fill URL with http://localhost:8086
5. Choose Server (Default) as access
6. Fill the database and the remaining fields and click Save & Test.

Basic auth and credentials must be left unflagged. Proxy is not required.

Now you are ready to add your first dashboard and launch some queries on a database.

InfluxDB Shell (CLI)

docker exec -it influxdb-grafana influx
