KubeInvaders

Chaos Engineering Tool for Kubernetes and Openshift

KubeInvaders is a game and it 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.

Actually this is an alpha release and it has been tested only with Openshift 3.9

How KubeInvaders Works

Install KubeInvaders on Openshift

If you deploy KubeInvaders on Openshift please configure corsAllowedOrigins in your /etc/origin/master/master-config.yaml

 corsAllowedOrigins:
   - (?i)//kubeinvaders.org(:|\z)

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

TARGET_NAMESPACE=foobar
ENDPOINT=https://ocmaster39:8443
ROUTE_URL=kubeinvaders.org
oc new-project kubeinvaders --display-name='KubeInvaders'
oc create sa kubeinvaders -n kubeinvaders
oc create sa kubeinvaders -n $TARGET_NAMESPACE
oc adm policy add-role-to-user edit -z kubeinvaders -n $TARGET_NAMESPACE

TOKEN=$(oc describe secret -n $TARGET_NAMESPACE $(oc describe sa kubeinvaders -n $TARGET_NAMESPACE | grep Tokens | awk '{ print $2}') | grep 'token:'| awk '{ print $2}')
oc process -f openshift/KubeInvaders.yaml -p ROUTE_URL=$ROUTE_URL -p TARGET_NAMESPACE=$TARGET_NAMESPACE -p ENDPOINT=$ENDPOINT TOKEN=$TOKEN | oc create -f -

Donwload KubeInvaders - External to Openshift (macOS or Linux clients)

Please check the releases page.

How Configure KubeInvaders - Running on Openshift

Change the following variables inside the kubeinvaders DeploymentConfig

• TARGET_NAMESPACE
• ENDPOINT
• TOKEN

How Configure KubeInvaders - Local execution

create the file $HOME/.KubeInv.json (the token should have permission for list and delete pods into the namespace).
