Deploying Druid On KIND

• In this tutorial, we are going to deploy an Apache Druid cluster on KIND.
• This tutorial can easily run on your local machine.

Prerequisites

To follow this tutorial you will need:

• The KIND CLI installed.
• The KUBECTL CLI installed.
• Docker up and Running.

Install Kind Cluster

Create kind cluster on your machine.

kind create cluster --name druid

Install Druid Operator

• Add Helm Repo

helm repo add datainfra https://charts.datainfra.io
helm repo update

• Install Operator

# Install Druid operator using Helm
helm -n druid-operator-system upgrade -i --create-namespace cluster-druid-operator datainfra/druid-operator

Apply Druid Customer Resource

• This druid CR runs druid without zookeeper, using druid k8s extension.

• MM less deployment.

• Derby for metadata.

• Minio for deepstorage.

• Run make helm-minio-install . This will deploy minio using minio operator.

• Once the minio pod is up and running in druid namespace, apply the druid CR.

• kubectl apply -f tutorials/druid-on-kind/druid-mmless.yaml -n druid

Here's a view of the druid namespace.
