  • For latest version set VERSION=v1.2.1
  • Or pick a version from here

Integrate with Kube-Prometheus Monitoring

If you have Kube-Prometheus installed in your cluster, you can have it monitor your dragonfly deployment by enbaling the serviceMonitor and prometheusRule in your values file. See an example below.

  1. serviceMonitor:
  2.   enabled: true
  4. prometheusRule:
  5.   enabled: true
  6.   spec:
  7.     - alert: DragonflyMissing
  8.       expr: absent(dragonfly_uptime_in_seconds) == 1
  9.       for: 0m
  10.       labels:
  11.         severity: critical
  12.       annotations:
  13.         summary: Dragonfly is missing
