Grandes coisas com recipientes: Grafana on Synology - Diskstation

Grafana é uma aplicação de código aberto multiplataforma para exibir graficamente dados de várias fontes de dados como InfluxDB, MySQL, PostgreSQL ou Prometheus. Hoje eu mostro como instalar um serviço Grafana no Synology DiskStation.

Passo 1: Preparar a Sinologia

Primeiro, o login do SSH deve ser ativado no DiskStation. Para fazer isso, vá para o “Painel de Controle” > “Terminal

Então você pode entrar via “SSH”, a porta especificada e a senha do administrador (usuários do Windows usam Putty ou WinSCP).

Eu inicio sessão via Terminal, winSCP ou Putty e deixo esta consola aberta para mais tarde.

Passo 2: Criar pasta Grafana

Eu crio um novo diretório chamado “grafana” no diretório Docker.

Com o comando “cd” procuro o directório Grafana:

–

Terminal

$ cd /volume1/docker/grafana/

Então eu crio um arquivo “grafana.yml” no diretório Grafana com este conteúdo:

version: "2"
services:
  grafana:
    image: grafana/grafana
    container_name: grafana_server_grafana
    restart: always
    ports:
      - 3000:3000
    networks:
      - grafana
    environment:
      - GF_SERVER_CERT_FILE=/etc/ssl/server.crt
      - GF_SERVER_CERT_KEY=/etc/ssl/server.key
      - GF_SERVER_PROTOCOL=https
      - GF_SERVER_HTTP_PORT=3000
    volumes:
      - ./grafana:/var/lib/grafana
      - ./ssl:/etc/ssl

  influxdb:
    image: influxdb
    container_name: grafana_server_influxdb
    restart: always
    ports:
      - 8086:8086
    networks:
      - grafana
    volumes:
      - ./influxdb:/var/lib/influxdb
      - ./ssl:/etc/ssl
    environment:
      - INFLUXDB_DB=telegraf
      - INFLUXDB_USER=telegraf
      - INFLUXDB_USER_PASSWORD=influxdb-password
      - INFLUXDB_ADMIN_ENABLED=true
      - INFLUXDB_ADMIN_USER=admin
      - INFLUXDB_ADMIN_PASSWORD=influxdb-password
      - INFLUXDB_HTTP_HTTPS_ENABLED=true
      - INFLUXDB_HTTP_HTTPS_CERTIFICATE=/etc/ssl/server.crt
      - INFLUXDB_HTTP_HTTPS_PRIVATE_KEY=/etc/ssl/server.key
      - INFLUXDB_HTTP_AUTH_ENABLED=true

  telegraf:
    image: telegraf
    container_name: grafana_server_telegraf
    restart: always
    environment:
      HOST_PROC: /rootfs/proc
      HOST_SYS: /rootfs/sys
      HOST_ETC: /rootfs/etc
    volumes:
     - ./telegraf.conf:/etc/telegraf/telegraf.conf:ro
     - /var/run/docker.sock:/var/run/docker.sock:ro
     - /sys:/rootfs/sys:ro
     - /proc:/rootfs/proc:ro
     - /etc:/rootfs/etc:ro

networks:
  grafana:

Eu crio mais duas subpastas para os dados:

–

Terminal

$ mkdir grafana
$ mkdir influxdb
$ chown -R 472:472 grafana

Como eu quero usar SSL para Grafana e a interface associada, um certificado ainda precisa ser criado:

–

Terminal

$ mkdir ssl
$ openssl genrsa -aes256 -passout pass:your-password -out ssl/server.pass.key 4096
$ openssl rsa -passin pass:your-password -in ssl/server.pass.key -out ssl/server.key
$ openssl req -new -key ssl/server.key -out ssl/server.csr
$ rm ssl/server.pass.key
$ openssl x509 -req -sha256 -days 365 -in ssl/server.csr -signkey ssl/server.key -out ssl/server.crt

Veja:

Finalmente, eu crio um arquivo “telegraf.conf” com este conteúdo:

  metric_buffer_limit = 10000

Agora inicie o servidor Grafana com esta chamada Compose:

–

Terminal

$ sudo docker-compose -f grafana.yml up

Passo 3: Configuração

Agora posso chamar o servidor, configurar o banco de dados, criar painel de controle e conectar mais dados de medição.
