The Noisy Neighbor Ate the Node
Incident Narrative
Token Goblin, explicitly non-human, plugs dozens of glowing appliances into one apartment until the entire building’s lights dim and neighboring pod rooms lose power.
“One tenant. Whole node.”
🔬Architectural Diagnosis & Root Cause Analysis
One workload consumes shared node resources without effective isolation.
One workload consumes shared node resources without effective isolation.
Use requests, limits, QoS and placement controls to contain resource contention.
“SYSTEM VERDICT: Use requests, limits, QoS and placement controls to contain resource contention.”

Kubernetes Apartment · Episode 1 · resource requests / limits
Every Pod Wanted the Penthouse
In an isometric apartment building, every tiny pod-tenant points at an oversized penthouse-sized room; the building fills immediately even though most tenants use one chair.
Kubernetes Apartment · Episode 2 · autoscaling signals / HPA
HPA Added Ten Roommates Because One Coughed
One pod-tenant coughs once; the apartment instantly duplicates ten new roommates into adjacent rooms, all turning on lights while the original cough stops.
Kubernetes Apartment · Episode 3 · liveness vs readiness probes
The Liveness Probe Evicted the Healthy Tenant
A healthy pod-tenant is briefly busy behind a closed bathroom door; an impatient building probe immediately throws his suitcase into the hall and replaces him, repeating the cycle.
Kubernetes Apartment · Episode 5 · persistent storage / stateful workloads
The Pod Moved Out; Its Data Didn’t
A pod-tenant happily moves from one apartment room to another carrying nothing; his filing cabinet remains bolted to the old room, and he reaches the new room with empty hands.
Kubernetes Apartment · Episode 6 · scheduling / resource governance
The Scheduler Finally Set House Rules
The chaotic isometric apartment begins with pods crowding random rooms; a scheduler board introduces sensible room capacities and placement zones, and tenants redistribute into a stable balanced layout.
