Prometheus Mysql Exporter
DEPRECATED and moved to https://github.com/prometheus-community/helm-charts
- 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 mysql.user="username",mysql.pass="password",mysql.host="example.com",mysql.port="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.
