Gamified chaos engineering tool for Kubernetes. It is like Space Invaders but the aliens are PODs
KubeInvaders has been developed using Defold (https://www.defold.com/).
Through KubeInvaders you can stress Kubernetes 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. |
| h | Show special keys. |
| q | Hide help for special keys. |
| i | Show pod's name. Move the ship towards an alien. |
| r | Refresh log of a pod when spaceship is over the alien. |
Move the spaceship over a white alien
# Set target_namespace and ingress.hostname!
git clone https://github.com/lucky-sideburn/KubeInvaders.git
kubectl create namespace kubeinvaders
helm install kubeinvaders --set-string target_namespace="namespace1\,namespace2" \
--namespace kubeinvaders ./helm-charts/kubeinvaders \
--set ingress.hostName=kubeinvaders.io
Set the following variables in Kubernetes Deployment or Openshift DeploymentConfig
| ENV Var | Description |
|---|---|
| ALIENPROXIMITY (default 15) | Reduce the value to increase distance between aliens |
| HITSLIMIT (default 0) | Seconds of CPU time to wait before shooting |
| UPDATETIME (default 1) | Seconds to wait before update PODs status (you can set also 0.x Es: 0.5) |
The easy way to install KubeInvader is run it on you workstation.
Create .KubeInv.json file on your home. This is an example:
{
"token": ".....",
"endpoint": "https://rancher.accolli.it:6443",
"namespace": "namespace1,namespace2"
}
To Install KubeInvaders on your Openshift Cluster clone this repo and launch the following commands:
oc create clusterrole kubeinvaders-role --verb=watch,get,delete,list --resource=pods,pods/log
TARGET_NAMESPACE=foobar,awesome-namespace
## 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"
oc new-project kubeinvaders --display-name='KubeInvaders'
oc create sa kubeinvaders -n kubeinvaders
oc adm policy add-cluster-role-to-user kubeinvaders-role -z kubeinvaders -n kubeinvaders
KUBEINVADERS_SECRET=$(oc get secret -n kubeinvaders --field-selector=type==kubernetes.io/service-account-token | grep 'kubeinvaders-token' | awk '{ print $1}' | head -n 1)
oc process -f openshift/KubeInvaders.yaml -p ROUTE_HOST=$ROUTE_HOST -p TARGET_NAMESPACE=$TARGET_NAMESPACE -p KUBEINVADERS_SECRET=$KUBEINVADERS_SECRET | oc create -f -How the configuration of KubeInvaders DeploymentConfig should be (remember to use your TARGET_NAMESPACE and ROUTE_HOST)
