Prometheus Mysql Exporter

• Installs prometheus mysql exporter

TL;DR;

$ helm install stable/prometheus-mysql-exporter

Introduction

This chart bootstraps a prometheus mysql exporter deployment on a Kubernetes cluster using the Helm package manager. The exporter can connect to mysql directly or using the Cloud SQL Proxy.

Installing the Chart

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

$ helm install --name my-release stable/prometheus-mysql-exporter --set datasource="username:password@(db:3306)/"

The command deploys a mysql exporter on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

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

Configuration

The following table lists the configurable parameters of the mysql exporter chart and their default values.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set mysql.user="username",mysql.password="password",mysql.host="localhost",mysql.port="3306"  \
    stable/prometheus-mysql-exporter

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/prometheus-mysql-exporter
