Loki Stack Helm Chart

Artifact Hub

This chart provides a batteries-included logging stack for Kubernetes:

  • Loki for log storage and querying
  • Grafana Alloy for cluster-wide log collection (Grafana’s replacement for deprecated Promtail and other collectors)
  • Optional kube-prometheus-stack for Grafana + Prometheus

Why?​

  • Upstream changes: The legacy loki-stack approach and Promtail are deprecated upstream; this chart exists to keep an easy-to-install stack using current Loki with Alloy.
  • Cluster-wide container logs: By default in this chart, Alloy is configured to collect all Kubernetes container logs from /var/log/pods/*/*/*.log across the cluster and forward them to Loki with useful labels (namespace/pod/container).
