KubeInvaders

KubeInvaders is a gamified chaos engineering tool for Kubernetes Clusters. It is like Space Invaders but the pods are alien ships

jump between namespaces pressing 'n' !

Description

KubeInvaders has been written with Defold (https://www.defold.com/).

Through KubeInvaders you can stress your Openshift cluster in a fun way and check how it is resilient.

Special Input Keys

Input	Action
n	Change namespace (you should define namespaces list. Ex: TARGET_NAMESPACE=foo1,foo2,foo3).
a	Switch to automatic mode.
m	Switch to manual mode.
h	Show special keys.
q	Hide help for special keys.
i	Show pod's name. Move the ship towards an alien.

Install KubeInvaders on Openshift

To Install KubeInvaders on your Openshift Cluster clone this repo and launch the following commands:

TARGET_NAMESPACE=foobar
## You can define multiple namespaces ex: TARGET_NAMESPACE=foobar,foobar2

# Choose route host for your kubeinvaders instance.
ROUTE_HOST=kubeinvaders.org

# Please add your source ip IP_WHITELIST. This will add haproxy.router.openshift.io/ip_whitelist in KubeInvaders route
# https://docs.openshift.com/container-platform/3.9/architecture/networking/routes.html#whitelist
IP_WHITELIST="93.44.96.4"
