Loki

Installing Loki Stack

  1. First add Loki’s chart repository to helm 
    1
    helm repo add grafana https://grafana.github.io/helm-charts
  2. Then update the chart repository 
    1
    helm repo update

This command will:

  • install grafana
  • install prometheus
  • install loki
  • enable persistence for your stack and create a PVC 
    1
    helm upgrade --install loki grafana/loki-stack  --set grafana.enabled=true,prometheus.enabled=true,prometheus.alertmanager.persistentVolume.enabled=false,prometheus.server.persistentVolume.enabled=false,loki.persistence.enabled=true,loki.persistence.storageClassName=longhorn,loki.persistence.size=5Gi

    To configure your StorageClass, you should specify loki.persistence.storageClassName=longhorn. In this instance, I am utilizing longhorn as the Kubernetes loghorn Provisioner.
