Grafana Loki Installation Deploy on Kubernetes Install Loki

Install the 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 cluster within a Kubernetes cluster.

If object storage is configured, this chart configures Loki to run read and write targets in a scalable mode, 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:
         s3: <WHAT SHOULD GO HERE?>
         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
