Install the Helm Chart

This Helm Chart installation runs the Grafana Loki cluster within a Kubernetes cluster.

If object storge is configured, this chart configures Loki to run read and write targets in a scalable, highly available architecture (3 replicas of each) designed to work with AWS S3 object storage. It will also configure meta-monitoring of metrics and logs.

It is not possible to run the scalable mode with the filesystem storage.

Before you begin:

  • Helm 3 or above. See Installing Helm.
  • A running Kubernetes cluster.
  • A Prometheus operator installation in case meta-monitoring should be used.

To deploy Loki in scalable mode:

  1. Add Grafana's chart repository to Helm:

    helm repo add grafana https://grafana.github.io/helm-charts

  2. Update the chart repository:

    helm repo update

  3. Configure the object storage:

    • Create the configuration file values.yaml:

      storage:
  bucketNames:
    chunks: chunks
    ruler: ruler
    admin: admin
  type: s3
  s3:
    endpoint: <endpoint>
    region: <AWS region>
    secretAccessKey: <AWS secret access key>
    accessKeyId: <AWS access key ID>
    s3ForcePathStyle: false
    insecure: false

      Consult the Reference for configuring other storage providers.

    • Define the AWS S3 credentials in the file.

  4. Upgrade the Loki deployment with this command.

    helm upgrade --values values.yaml loki grafana/loki
