Helm

Use Helm to Deply a Presto Cluster

The Presto community also provides the helm chart to install Presto cluster on a Kubernetes cluster. Here is how you can leverage it to create a Presto cluster containing the same settings for this workshop.

Prerequisite

In order to use Presto helm chart, make sure the following tools are available

• Helm
• A Kubernetes cluster
• kubectl

Instructions

1. Add the Presto Helm Chart Repository:

   Helm chart repository is a location where packaged charts can be stored and shared. Use the following command to add Presto charts repository to Helm client configuration:

   helm repo add presto https://prestodb.github.io/presto-helm-charts
   

2. Create a namespace for the Presto cluster

   Use a dedicate namespace to deploy the Presto cluster. In this case, the namespace is called presto

   kubectl create ns presto
   

3. Deploy MongoDB and MySQL

   kubectl apply -n presto -k helm/kustomize
   

4. Populate the Data into MongoDB and MySQL

   kubectl exec -n presto -ti svc/presto-mongo mongosh < data/mongo.sql
   kubectl exec -n presto -ti svc/presto-mysql -- mysql -u root -ppresto < data/mysql.sql
   

5. Install a Presto Chart

   Install a Presto Helm chart and it will provision a Presto cluster using the settings from the helm/values.yaml

   helm install presto presto/presto -f helm/values.yml -n presto
