Presto Helm Charts

License

Repository for Presto Helm charts.

Add Presto charts Helm repo

Use the following command to add Presto charts repository to Helm configuration:

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

Debugging chart templates

Use helm template --debug to render the chart templates locally, for example, to check correctness when Ingress is enabled:

$ helm template my-presto charts/presto --set ingress.enabled=true --debug

Use helm install --dry-run --debug to render the chart templates on a server side without creating resources. The command simulates installation, which is useful to check if the chart and configuration are valid for a specific Kubernetes cluster:

$ helm install my-presto charts/presto --set ingress.enabled=true --dry-run --debug

Running locally

Minikube can be used to deploy the chart and run Presto locally. The following commands start minikube instance and open Kubernetes cluster dashboard in the default web browser:

$ minikube start --cpus=4 --memory=8g --addons=ingress --addons=ingress-dns
$ minikube dashboard
