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 apache-druid https://apache.github.io/druid-operator
helm repo update
  • Install Operator
# Install Druid operator using Helm
helm -n druid-operator-system upgrade -i --create-namespace cluster-druid-operator apache-druid/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.
