Grafana – mit Docker Compose und Traefik installieren

Hier zeige ich euch, wie ihr in ein paar Minuten ein cooles Dashboard bekommt, welches euch diverse Sachen über euren Server anzeigt. Traefik dient uns hier als Reverse Proxy und stellt später den Dienst verschlüsselt per TLS bereit.

Wer Traefik noch nicht installiert hat, findet hier eine Anleitung, wie ihr dies schnell tun könnt.

Als Grundlage meiner Anleitung dient dient diese Anleitung. Ich habe diese jedoch etwas erweitert und an Traefik angepasst.

So kann später dann euer Dashboard aussehen:

Dazu werden wir gleich folgende Tools installieren

• Prometheus
• node-exporter
• cadvisor
• grafana

1. Ordner anlegen

Zuerst legen wir uns passende Ordner-Strukturen an.

mkdir -p /opt/containers/grafana/{grafana,prometheus}

Nun ändern wir noch die Berechtigungen.

chown 1000:1000 /opt/containers/grafana/grafana

2. Docker Compose anlegen

Hier legen wir die Docker Compose an.

cd /opt/containers/grafana/
nano docker-compose.yml

---
version: '3'

services:
  mon_prometheus:
    image: prom/prometheus:latest
    container_name: mon_prometheus
    restart: unless-stopped
    volumes:
      - $PWD/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml
    depends_on:
      - mon_node-exporter
      - mon_cadvisor
    networks:
      - default

  mon_node-exporter:
    image: prom/node-exporter:latest
    container_name: mon_node-exporter
    restart: unless-stopped
    volumes:
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /:/rootfs:ro
    command:
      - '--path.procfs=/host/proc'
      - '--path.sysfs=/host/sys'
      - '--path.rootfs=/rootfs'
      - '--collector.filesystem.ignored-mount-points="^(/rootfs|/host|)/(sys|proc|dev|host|etc)($$|/)"'
      - '--collector.filesystem.ignored-fs-types="^(sys|proc|auto|cgroup|devpts|ns|au|fuse\.lxc|mqueue)(fs|)$$"'
    networks:
      - default

  mon_cadvisor:
    image: gcr.io/cadvisor/cadvisor
    container_name: mon_cadvisor
    restart: unless-stopped
    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:rw
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
    networks:
      - default

  mon_grafana:
    image: grafana/grafana:latest
    container_name: mon_grafana
    restart: unless-stopped
    volumes:
      - /opt/containers/grafana/grafana:/var/lib/grafana
    user: "1000" # USER ID des Docker Users anpassen
    depends_on:
      - mon_prometheus
    networks:
      - default

    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.grafana.entrypoints=http"
      - "traefik.http.routers.grafana.rule=Host(`grafana.euredomain.de`)"  ## Hier eure Domain eingeben ##
      - "traefik.http.middlewares.grafana-https-redirect.redirectscheme.scheme=https"
      - "traefik.http.routers.grafana.middlewares=grafana-https-redirect"
      - "traefik.http.routers.grafana-secure.entrypoints=https"
      - "traefik.http.routers.grafana-secure.rule=Host(`grafana.euredomain.de`)" ## Hier eure Domain eingeben ##
      - "traefik.http.routers.grafana-secure.tls=true"
      - "traefik.http.routers.grafana-secure.tls.certresolver=http"
      - "traefik.http.routers.grafana-secure.service=grafana"
      - "traefik.http.services.grafana.loadbalancer.server.port=3000"
      - "traefik.docker.network=proxy"
      - "traefik.http.routers.grafana-secure.middlewares=secHeaders@file"

    networks:
      - proxy
      - default

networks:
  proxy:
    external: true

Notwendige Anpassungen:

1. 2x eure URL eingeben bei Traefik

3. prometheus.yml anlegen

Nun legen wir noch eine Konfigurationsdatei für Prometheus an.

nano /opt/containers/grafana/prometheus/prometheus.yml

global:
  scrape_interval: 15s
  evaluation_interval: 15s
rule_files:
scrape_configs:
  - job_name: 'node-exporter'
    static_configs:
      - targets: ['mon_node-exporter:9100']

  - job_name: 'cadvisor'
    static_configs:
      - targets: ['mon_cadvisor:8080']

4. Grafana starten

Wie gewohnt starten wir nun Grafana mittels folgendem Befehl:

docker-compose -f /opt/containers/grafana/docker-compose.yml up -d

5. Grafana Konfigurieren

5.1 Einloggen

Nun geht ihr auf “grafana.euredomain.de” und solltet folgendes sehen:

Die Zugangsdaten lauten:

• Name: admin
• Passwort: admin

Wenn ihr euch einloggt, werdet ihr aufgefordert das Kennwort zu ändern.

Nun solltet ihr folgendes sehen.

5.2 Mit Prometheus Datenbank verbinden

Nun klickt ihr auf “Add data source”.

Hier wählt ihr “Prometheus” aus.

Hier gebt ihr nun unter “URL” folgendes ein:

http://mon_prometheus:9090

Nun scrollt ihr nach unten und klickt auf “Save & Test”. Wenn alles ok ist, dann sollte es bei euch so aussehen.

5.3 Dashboard hinzufügen

Ihr könnt euch nun ein Dashboard selbst zusammenbauen oder eins kostenlos von der Grafana Community beziehen.

Wenn ihr mein Dashboard haben wollt, so müsst ihr folgendes tun.

Klickt auf das “+” links oben und wählt “Import” aus.

Hier kopiert ihr nun folgenden Code in das Feld. Ihr könnt den Code komplett markieren und dann kopieren.
