使用Grafana來視覺化Prometheus蒐集到的metrics

Setup

Grafana Container (use docker-compose)

如果不想手動設定帳密可以把環境變數移除，那就會使用預設帳密admin

grafana:
  image: grafana/grafana:8.1.5
  restart: unless-stopped
  volumes:
    - ./grafana/data:/var/lib/grafana
    - ./grafana/provisioning:/etc/grafana/provisioning
  environment:
    - GF_SECURITY_ADMIN_USER=admin
    - GF_SECURITY_ADMIN_PASSWORD__FILE=/run/secrets/admin_password
    - GF_USERS_ALLOW_SIGN_UP=false
  ports:
    - 3000:3000
  secrets:
    - source: gf_admin_password
      target: admin_password
secrets:
  gf_admin_password:
    file: ./grafana/secrets/admin_password

用檔案來存密碼會比直接將密碼寫在yaml檔內更安全一點，如果喜歡直接把密碼用環境變數儲存或是直接寫到yaml檔內的話，可以把yaml檔改寫成
