## What it is
KUARD (Kubernetes Up And Running Demo) is a demo web application written in Go with a React frontend, designed to accompany the 'Kubernetes Up and Running' book. It simulates workloads like RSA key generation and includes a simple queue server, making it useful for testing Kubernetes deployments, liveness probes, and scaling behaviors.

## Use cases
- demo app to practice kubernetes deployments
- test kubernetes liveness and readiness probes
- simulate batch worker workloads in a cluster
- learn kubernetes from the up and running book
- test container image builds and registry pushes
- experiment with kubernetes scaling and upgrades

## When to choose
- you are learning Kubernetes and need a realistic demo workload
- you need a sample app to test deployments, probes, and scaling
- you want a containerized demo app for workshops or tutorials

## When to avoid
- you need a production-ready web application
- you need a full-featured HTTP framework or microservice template
- you are not working with containers or Kubernetes

## Facets
- artifact type: application
- maturity: maintenance
- function: http-server, developer-tools, simulation
- domain: developer-tools, education
- platform: go
- tags: demo-app, kubernetes-training, sample-application, learning-resource, containerized, containers, devops, docker, kubernetes, linux, web-server
