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


Install to Kubernetes with Helm (v3+)

Artifact HUB

helm repo add kubeinvaders

kubectl create namespace kubeinvaders

helm install kubeinvaders --set-string target_namespace="namespace1\,namespace2" \
-n kubeinvaders kubeinvaders/kubeinvaders --set --set image.tag=v1.9


At the top you will find some metrics as described below:

Alt Text

Current Replicas State Delay is a metric that show how much time the cluster takes to coming back at the desired state of pods replicas.

This is a control-plane you can use to switch off & on various features.

Press + or - buttons to increase or decrease the game screen.

Chaos Containers for masters and workers nodes

  • Select from the menu "Show Current Chaos Container for nodes" for watching which container start when you fire against a worker node (not an alien, they are pods).

  • Select from the menu "Set Custom Chaos Container for nodes" for using your preferred image or configuration against nodes.

Known problems

  • It seems that KubeInvaders does not work with EKS because of problems with ServiceAccount. Work in progress!

Prometheus Metrics

KubeInvaders exposes metrics for Prometheus through the standard endpoint /metrics

This is an example of Prometheus configuration

- job_name: kubeinvaders
  - targets:
    - kubeinvaders.kubeinvaders.svc.cluster.local:8080

Example of metrics

Metric Description
chaos_jobs_node_count{node=workernode01} Total number of chaos jobs executed per node
chaos_node_jobs_total Total number of chaos jobs executed against all worker nodes
deleted_pods_total 16 Total number of deleted pods
deleted_namespace_pods_count{namespace=myawesomenamespace} Total number of deleted pods per namespace
