K8s Games

Learn Kubernetes by playing. Deploy pods, fix CrashLoopBackOff, type real kubectl commands — all in a 3D sim that runs in your browser.

Get Started

Visit k8sgames.com and pick a mode. No install, no signup, no build step.

Just here to diagram? Go straight to k8sgames.com/draw — drag K8s resources onto a 3D canvas, draw connections, export YAML or PNG, and share via URL.

Or run locally:

git clone https://github.com/rohitg00/k8sgames.git
cd k8sgames
python3 -m http.server 8080
# Open http://localhost:8080

How to Play

1. Pick a game mode from the main menu
2. Click resources from the left palette to place them in your cluster
3. Drag resources to reposition them anywhere
4. Click any resource to inspect it (status, YAML, kubectl describe)
5. Right-click for actions (Scale, Delete, Logs, Restart)
6. Press / to open the kubectl command bar
7. Handle incidents as they appear — diagnose and fix like a real SRE
8. Press ? anytime for help

Game Modes

Mode	What You Do
Campaign	20 levels across 5 chapters. Learn pods, deployments, networking, storage, and production K8s
Chaos	Endless survival. Incidents escalate until your cluster breaks. How long can you last?
Sandbox	Free build. Design any cluster, get scored 0-100 by the Architecture Advisor
Challenges	10 timed scenarios. Deploy apps, fix outages, race the clock

K8s Draw (/draw)

A 3D Kubernetes architecture whiteboard. Like Excalidraw but for K8s.

• Drag-drop 21 resource types onto a 3D canvas
• Draw connection lines between resources
• Double-click to rename any resource
• Auto-layout organizes by tier (Nodes, Workloads, Networking, Storage, RBAC)
• Export as YAML (with correct apiVersions) or PNG
• Share diagrams via URL — one-click copy, open anywhere
• Edit properties: name, namespace, labels, replicas
• Right-click to delete, Del key for selected

No game logic, no incidents, no scoring — just diagramming.

What's In It

25 K8s resources — Pod, Deployment, ReplicaSet, StatefulSet, DaemonSet, Job, CronJob, Service, Ingress, NetworkPolicy, ConfigMap, Secret, PVC, PV, StorageClass, Node, Namespace, HPA, ResourceQuota, PodDisruptionBudget, ServiceAccount, Role, ClusterRole, RoleBinding, ClusterRoleBinding. Each has a unique 3D shape, color, and real K8s behavior.

29 incidents — OOMKilled, CrashLoopBackOff, ImagePullBackOff, node NotReady, DNS failures, PVC pending, API throttling, rollout stuck, certificate expiry, HPA flapping, and more. Investigate with kubectl describe/logs, then fix.

kubectl command bar — type real commands: get pods, describe deployment nginx, scale deployment nginx --replicas=3, logs pod-1, rollout status, drain node-1. Tab completion included.

Visual connections — animated lines show ownership chains (Deployment -> ReplicaSet -> Pod) and network routing (Service -> Pods) based on label selectors. Place a Service and pick which Deployment it connects to.

Edit resources — click Edit on any resource to modify labels, replicas, selectors, and service types. Quick-connect buttons let you wire a Service to an existing Deployment in one click.

Architecture Advisor — scores your cluster design across HA, security, scalability, cost, and 6 other categories.

40 achievements and a 30-level XP system from Novice to CKA-ready.

RBAC simulation — ServiceAccounts, Roles, ClusterRoles, RoleBindings, and ClusterRoleBindings with real rule definitions and wildcard detection.
