Grafana Mimir Helm Chart

This Helm chart deploys a standalone instance of Grafana Mimir, configured to run in non-distributed mode. It provides flexibility for users to customize their Grafana Mimir instance by allowing custom configurations through the config field in the values.yaml file.

Features

• Customizable Configuration: Add your own Grafana Mimir settings using the config field in values.yaml.
• StatefulSet Deployment: Ensures stability and persistent identity for each Grafana Mimir pod.

Prerequisites

• Kubernetes 1.20+
• Helm 3.0+

Installation

Clone the repository. To install the chart:

helm install <release-name> . -f values.yaml [-f custom-values.yaml]

Uninstallation

To uninstall the chart:

helm uninstall <release-name>

Configuration

The following table lists the configurable parameters of the chart and their default values:

Parameter	Description	Default
replicaCount	Number of replicas for the StatefulSet	1
image.repository	Grafana Mimir image repository	grafana/mimir
image.tag	Grafana Mimir image tag	latest
image.pullPolicy	Image pull policy	IfNotPresent
config	Custom Grafana Mimir configuration	{}
resources	Resource requests and limits	{}
service.type	Kubernetes service type	ClusterIP
service.port	Port for accessing Grafana Mimir	8080

To override these values, create a custom-values.yaml file and provide your own settings:

replicaCount: 1
config:
  retention:
    retentionPeriod: 1d

Then install the chart with your custom values:

helm install <release-name> . -f values.yaml -f custom-values.yaml

Config file is mounted at /etc/mimir.yaml.

StatefulSet Deployment

This chart uses a StatefulSet instead of a Deployment to ensure consistent identity and persistent storage for each Grafana Mimir pod. This is essential for stable operation in standalone mode.

Example

Here's an example values.yaml file to deploy Grafana Mimir with custom settings:

replicaCount: 1
config:
  retention:
    retentionPeriod: 1d
resources:
  requests:
    memory: "2Gi"
    cpu: "1"
  limits:
    memory: "4Gi"
    cpu: "2"
service:
  type: LoadBalancer
