ziggy

Ziggy is an Helm chart for deploying ziggy app. It's a special app created in order to demoing stuff on K8s:

• Health check
• Readiness
• CPU intensive workloads (eg HPA)
• Memory leaked apps

How it works

Overview

There is two containers:

• spaceboy: a simple handler:
  • "/" -> return Pod hostname
  • "/healthz" -> return http 200 during 120s (by default), then http 503
  • "/ready" -> return http 503 during 30s (by deault), then http 200
• spaceoddity:
  • can simulate a CPU intensive app
  • or an app with a memroy leak (these to settings are exclisives)

How to use it

There is a configMap with default options:

configmap:
  # args for spaceboy container, eg "-healthz 120", "-ready 60"
  spaceboy:
    key: spaceboy-args
    value: ["-healthz 300"]
  # args for spaceoddity container, eg "-cpu 300", "-mem"
  spaceoddity:
    key: spaceoddity-args
    value: ["-cpu 0"]

Just overwrite the options you need:

If you need to change readiness dealay to 60 seconds:

$ healm install ziggy --set configmap.spaceboy.value="-ready 60"

If you have to simulate a memory leak during 5 minutes:

$ healm install ziggy --set configmap.spaceoddity.value="-mem 300"
