k8sgames
k8sgames is a browser-based 3D simulation game that teaches Kubernetes concepts through interactive play. Users deploy pods, fix failures, and run real kubectl commands without installation, plus a diagramming tool for designing cluster architectures.

What k8sgames is
A vanilla JavaScript (Three.js r152) application delivering a 25-resource K8s simulator with 29 incident types, real kubectl command execution, RBAC simulation, and a YAML export/import architecture diagrammer. Runs entirely client-side; no backend or build step required.

Best use cases
Implementation considerations
- Browser-based delivery: requires no server infrastructure; users visit k8sgames.com or clone and run `python3 -m http.server`. Verify browser compatibility (WebGL for Three.js) across target user devices.
- No persistence layer: game state is in-browser memory only. Local save/restore is not documented; closing the tab loses progress unless YAML is manually exported.
- kubectl command bar is a UI simulation, not a real kubectl client. Commands are parsed and simulated; they do not connect to actual clusters.
- RBAC and incident simulation are rule-based, not cryptographically enforced. Suitable for learning but not for security policy testing.
- 90+ JavaScript files, ~50K lines. Maintenance and updates depend on a single maintainer (rohitg00). Code review and contribution process not documented.
When to avoid it — and what to weigh
- Need production cluster simulation with multi-node networking — k8sgames is a learning visualization, not a realistic multi-node scheduler. It does not simulate actual etcd, API server, kubelet behavior, or network I/O.
- Require offline-first or air-gapped deployment — Project is designed as a web app (k8sgames.com). Local http.server mode works but lacks any documented sync, persistence, or enterprise deployment model.
- Need integration with existing CI/CD or cluster tools — k8sgames is an isolated educational sandbox with no API, webhooks, or adapters to real clusters, registries, or deployment pipelines.
- Seeking formal training certification or compliance tracking — Achievement system exists (40 achievements, 30-level XP), but there is no LMS integration, completion certificates, audit logs, or SCORM export.

k8sgames is a client-side simulation with no backend or user authentication. Incidents and kubectl commands are simulated in-browser; no real cluster access or sensitive data is exposed. RBAC simulation is for learning purposes only and does not enforce cryptographic policy. If deployed in an organization, confirm that browser sandbox restrictions (CORS, CSP, WebGL) meet security posture requirements. No known CVEs documented; however, dependency security (Three.js r152) should be verified independently.
Alternatives to consider
Katacoda / Killercoda
Interactive terminal-based Kubernetes labs with real clusters. More hands-on but requires account setup and internet connectivity per scenario.
Minikube + kubectl CLI
Local Kubernetes cluster for learning. Lowest-level hands-on experience but steeper learning curve; no gamification or visual scaffolding.
Kubernetes 'kind' (in Docker) + custom exercises
Lightweight multi-node cluster in containers; allows real kubectl and debugging. Requires Docker and CLI skills; no built-in curriculum.
