proxysql

A proxysql Helm chart for Kubernetes. Offers option to expose web interface through Ingress. Uses ServiceMonitor to collect metrics.

TL;DR;

helm repo add christianknell https://christianknell.github.io/helm-charts
helm repo update
helm install my-release christianknell/proxysql

Introduction

This chart bootstraps a ProxySQL deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

  • Kubernetes 1.19+

Installing the Chart

To install the chart with the release name my-release:

helm repo add christianknell https://christianknell.github.io/helm-charts
helm repo update
helm install my-release christianknell/proxysql

These commands deploy proxysql on the Kubernetes cluster in the default configuration. The Values section lists the values that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall the my-release deployment:

helm uninstall my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.
