Installation

Install using Helm

Install single binary Loki

Open source

Install the Single Binary Helm Chart

You can use Grafana Cloud to avoid installing, maintaining, and scaling your own instance of Grafana Loki. Create a free account to get started, which includes free forever access to 10k metrics, 50GB logs, 50GB traces, 500VUh k6 testing & more.

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, 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

Helm 3 or above. See Installing Helm.
A running Kubernetes cluster

To deploy Loki in monolithic mode:

Add Grafana’s chart repository to Helm:

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

Update the chart repository:
bash
```
helm repo update
```

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:
    type: 's3'
    s3:
      endpoint: foo.aws.com
      bucketnames: loki-chunks
      secret_access_key: supersecret
      access_key_id: secret
singleBinary:
  replicas: 3

Deploy the Loki cluster using one of these commands.
- Deploy with the defined configuration:
  bash
```
helm install --values values.yaml loki grafana/loki
```
- Deploy with the defined configuration in a custom Kubernetes cluster namespace:
  bash
```
helm install --values values.yaml loki --namespace=loki grafana/loki
```
