KubeInvaders - Chaos Engineering Tool for Kubernetes and Openshift
0 likes244 views
Kubeinvaders is a gamified chaos engineering tool for Kubernetes and Openshift. It tests how resilient clusters are to unexpected pod deletions by simulating alien pods that can be shot down. It collects metrics like pod restart times and is useful for tuning readiness probes. The presentation demonstrated how to install and configure Kubeinvaders, discussed its arcade mode for increasing difficulty, and showed a demo of it in action.

KubeInvaders - Chaos Engineering Tool for Kubernetes and Openshift
- 1. Gamified Chaos Engineering Tool For Kubernetes Eugenio Marzo - Service Manager & DevOps Engineer @ Sourcesense
- 2. ● Quick introduction to this talk ● Why is important chaos engineering against Kubernetes ● What is Kubeinvaders ● How to install ● Configuration and input keys ● Arcade Mode ● Demo Agenda
- 3. ➢ I am not a game developer. ➢ Kubeinvaders is a game! Please do not take me seriously. ➢ Yes I know… with few lines of Bash the result is the same (but it is not funny). Things you should know to attend this talk
- 4. https://principlesofchaos.org https://thenewstack.io/how-chaos-engineering-ca n-drive-kubernetes-reliability/ Chaos Engineering is the discipline of experimenting on a system in order to build confidence in the system capability to withstand turbulent conditions in production.
- 5. I love but this is a little bit boring...
- 6. This is better! But still boring...
- 7. … this is much better!
- 9. ● It is a gamified Chaos Engineering tool for Kubernetes and Openshift ● Aliens are PODs of a Kubernetes cluster ● It is useful to test how resilient a cluster is, in a funny way What is Kubeinvaders?
- 10. ● Test how your K8S clusters are resilients on unexpected PODs deletions ● Collect metrics like PODs restart time ● Tuning readiness probes Use cases
- 11. Pods are designed as relatively ephemeral, disposable entities. When a Pod gets created (directly by you, or indirectly by a Controller), it is scheduled to run on a Node in your cluster. The Pod remains on that Node until the process is terminated, the pod object is deleted, the Pod is evicted for lack of resources, or the Node fails. https://kubernetes.io/docs/concepts/workloads/pods/pod-overview/
- 12. People use Kubeinvaders for fun and demos...
- 14. Automatic pilot - key ‘a’
- 15. Manual pilot - key ‘m’ (default)
- 16. Get PODs name - key ‘i’
- 17. Help - key ‘h’
- 18. Jump between namespaces - key ‘n’ (my preferred feature…)
- 19. Install Kubeinvaders on Openshift
- 21. Configure Kubeinvaders on Openshift
- 22. Arcade Mode - Make the game more difficult it will be merged in the next release of Kubeinvaders and will be shown during the demo ENV Variable Default Value Description ALIENPROXIMITY 15 Reduce the value to increase distance between aliens HITSLIMIT 0 Seconds of CPU time to wait before shooting UPDATETIME 0.3 Seconds to wait before update PODs status
- 23. How Kubeinvaders is made Defold html5 Docker build html 5 bundle copy to image with Ngnix
- 24. KubeInvaders runs as a pod in your cluster POD
- 25. Network Flow BrowserClient Workstation Openshift Router / Ingress POD Kubernetes API Server
