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

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

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.
