Overview

This guide provides a walkthrough on how to deploy a GreptimeDB cluster on Kubernetes.

Prerequisites

• Kubernetes >= 1.18

  NOTE

  You can use kind or Minikube to create a local Kubernetes cluster for testing.

• Helm v3: A package manager for Kubernetes.

• kubectl: A command-line tool for interacting with Kubernetes clusters.

Add Helm repository

Use the command below to add the GreptimeDB Helm chart repository.

helm repo add greptime https://greptimeteam.github.io/helm-charts/
helm repo update

You can find the maintained Helm charts in the GitHub repository.

Components

The deployment on Kubernetes involves the following components:

• GreptimeDB Operator: Assists engineers in managing GreptimeDB clusters effectively on Kubernetes.
• GreptimeDB Cluster: The main database cluster.
• etcd Cluster: etcd is a consistent and highly available key value store used for GreptimeDB cluster metadata storage.

Next Steps

To deploy GreptimeDB on Kubernetes, follow these steps:

• GreptimeDB Operator: This section guides you on installing the GreptimeDB Operator.
• Deploy GreptimeDB Cluster: This section provides instructions on how to deploy etcd cluster and GreptimeDB cluster on Kubernetes.
• Destroy Cluster: This section describes how to uninstall the GreptimeDB Operator and the GreptimeDB cluster.
