Prometheus Operator

Description

The Prometheus Operator provides a cluster monitoring solution using Prometheus, which is an open source monitoring system and alerting toolkit.

This repository contains a Juju Charm for deploying the monitoring component of Prometheus in a Kubernetes cluster. The alerting component of prometheus is offered through a separate Charm.

Setup

A typical setup using snaps, for deployments to a microk8s cluster can be done using the following commands

sudo snap install microk8s --classic
microk8s.enable dns storage registry dashboard
sudo snap install juju --classic
juju bootstrap microk8s microk8s
juju create-storage-pool operator-storage kubernetes storage-class=microk8s-hostpath

Build

Install the charmcraft tool

sudo snap install charmcraft

Build the charm in this git repository

charmcraft build

Usage

Create a Juju model for your monitoring operators

juju add-model lma

Deploy Prometheus using its default configuration.

juju deploy ./prometheus.charm

View the Prometheus dashboard

  1. Use juju status to determine IP of the Prometheus unit
  2. Navigate to http://<IP-Address>:9090 using your browser

If required, remove the deployed monitoring model completely

juju destroy-model -y lma --no-wait --force --destroy-storage
