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' !
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.
| 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 |
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"
