Install the monolithic Helm chart

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

If you set the singleBinary.replicas value to 1, this chart configures Loki to run the all target in a [monolithic mode]({{< relref "../../../../get-started/deployment-modes#monolithic-mode" >}}), designed to work with a filesystem storage. It will also configure meta-monitoring of metrics and logs. If you set the singleBinary.replicas value to 2 or more, this chart configures Loki to run a single binary in a replicated, highly available mode. When running replicas of a single binary, you must configure object storage.

Before you begin: Software Requirements

To deploy Loki in monolithic 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. Create the configuration file values.yaml:

    • If running a single replica of Loki, configure the filesystem storage:

      loki:
  commonConfig:
    replication_factor: 1
  storage:
    type: 'filesystem'
singleBinary:
  replicas: 1

    • If running Loki with a replication factor greater than 1, set the desired number replicas and provide object storage credentials:

      loki:
  commonConfig:
    replication_factor: 3
  storage:
    bucketNames:
      chunks: loki-chunks
      ruler: loki-ruler
      admin: loki-admin
    type: 's3'
    s3:
      endpoint: foo.aws.com
      secretAccessKey: supersecret
      accessKeyId: secret
singleBinary:
  replicas: 3

  4. Deploy the Loki cluster using one of these commands.

    • Deploy with the defined configuration:

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

    • Deploy with the defined configuration in a custom Kubernetes cluster namespace:

      helm install --values values.yaml loki --namespace=loki grafana/loki
