What KubeInvaders is

KubeInvaders is a free, open-source tool for learning about Kubernetes resilience through interactive disruption exercises. Users attack pods or nodes and observe how the cluster responds, with examples covering pod recovery, scheduling, node pressure, namespace isolation, and recovery time. Its container includes a simulated Kubernetes cluster powered by KWOK, where nodes and pods are simulated and nothing real is deleted.

For exercises on a real cluster, KubeInvaders can connect through the web console or container environment variables. The connection uses an API endpoint, ServiceAccount token, and namespaces, with a CA certificate available as an option. It runs as a container with Docker or Podman and can be run from a workstation or self-hosted against a Kubernetes cluster. The interface includes automatic chaos experiments, shuffle, namespace switching, pod-name visibility controls, and zoom.

Documentation lists URL monitoring during chaos sessions, along with Prometheus metrics and a Grafana dashboard. The project describes uses in Kubernetes teaching, resilience testing, and technology conference demonstrations. It is licensed under Apache 2.0. Its current README says official Helm chart support has been discontinued, though the legacy chart can be used as a starting point.

Who it suits

KubeInvaders suits developers learning how Kubernetes deployments behave under disruption, as well as teams teaching Kubernetes or demonstrating resilience. It is also intended for resilience testing, provided users configure access to the cluster they want to exercise.

What it does well

Includes a KWOK-powered simulated cluster that does not delete real resources.
Supports exercises against a real cluster using a ServiceAccount token.
Documents URL monitoring, Prometheus metrics, and a Grafana dashboard.
Interface includes automatic experiments and namespace switching.
Licensed under Apache 2.0 and free to use.

What to know first

The latest release says Helm installation support has been discontinued.
A missing, invalid, or expired token prevents Kubernetes API calls.

Limits

The included demo simulates nodes and pods, so it does not delete real resources. Official Helm installation support has been discontinued; the legacy chart may be used as a starting point.

Getting started

Open the KubeInvaders website.
Run the container with Docker or Podman.
Use the included KWOK-powered demo, or configure access to a real Kubernetes cluster.
For a real cluster, provide the API endpoint, ServiceAccount token, namespaces, and optionally a CA certificate.
Configure Kubernetes service-account and RBAC access, then run an exercise and observe the cluster.

Verdict

Pick KubeInvaders for interactive Kubernetes learning or resilience exercises, especially when you want a simulated mode before connecting a real cluster. Look elsewhere if official Helm installation support is essential, or take care with cluster credentials and TLS configuration when connecting to a real environment.

Questions

Is KubeInvaders free and open source?

Yes. It is free and licensed under Apache 2.0.

Can I try it without disrupting a real cluster?

Yes. Its container includes a simulated Kubernetes cluster powered by KWOK, where nodes and pods are simulated and nothing real is deleted.
