observability-stack-template

main

This repo is a minimized example of deploying observability stack to k8s.

Prerequisites

The following dependencies needs to be installed on the local machine to work with template:

Current list of components

  • Grafana
  • Loki
  • Prometheus
  • Promtail
  • Echo server app for demo purposes
  • Python demo app for demo purposes

Quickstart

To quickly deploy all componets for observability stack template, the startup script can be used:

✍️  Usage: ./scripts/start.sh <command>
	Please specify a command to run.
	Example: ./scripts/start.sh apply - to create minikube cluster and install observabilitty stack dependecies + demo apps.
	Example: ./scripts/start.sh destroy - to destroy created components.

To deploy all componets, invoke apply command:

> ./scripts/start.sh apply
✍️  Starting script...
✍️  Checking dependencies.
✅ All needed dependencies are installed.
✍️  This will create minikube cluster and install obesrvability stack. Do you wish to proceed? [y/n]

To cleanup all deployed components and minikube cluster, invoke destroy command:

> ./scripts/start.sh destroy
✍️  Starting script...
✍️  Checking dependencies.
✅ All needed dependencies are installed.
✍️  This will delete minikube cluster and uninstall obesrvability stack. Do you wish to proceed? [y/n]

NOTE:
✍️ Script does not shutdown the minikube cluster and does not uninstall helm resources automatically!

Manual operations

It's possible to omit startup script and operate with observability stack via plain minikube and terraform commands. Please use following guides for that:

Also it's possible to deploy only part of observability stack components by overriding variables declared in variables file.
Please use the following guide to get more context on terraform variables:
