Install on Kubernetes with Helm Chart

Prerequisites​

  • This manual uses Helm to deploy Dragonfly on a Kuberenetes cluster. See Install Helm
  • A Kuberenetes cluster (See Kind or Minikube if you want to experiment locally)
  • For latest version set VERSION=v1.3.0
  • Or pick a version from here

Install a standalone master​

helm upgrade --install dragonfly oci://ghcr.io/dragonflydb/dragonfly/helm/dragonfly --version $VERSION

Install a standalone master with snapshot taken every minute​

Create or add to your myvals.yaml values file

storage:
  enabled: true
  requests: 128Mi # Set as desired

extraArgs:
  - --dbfilename=dump.rdb
  - --save_schedule=*:* # HH:MM glob format

  runAsUser: 1000

helm upgrade -f myvals.yaml --install dragonfly oci://ghcr.io/dragonflydb/dragonfly/helm/dragonfly --version $VERSION

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.

serviceMonitor:
  enabled: true

prometheusRule:
  enabled: true
  spec:
    - alert: DragonflyMissing
      expr: absent(dragonfly_uptime_in_seconds) == 1
      for: 0m
      labels:
        severity: critical
      annotations:
        summary: Dragonfly is missing
        description: "Dragonfly is missing"
