The Service selects nobody
A Service has no endpoints although Pods report Ready.
INITIAL ALERT
A Service has no endpoints although Pods report Ready.
You are primary on-call. Establish the failure domain, protect healthy capacity, and choose the safest next action.
Direct Pod requests succeed on the expected port.
The decisive evidence and solution remain locked inside the simulation.WHAT THIS TESTS
Production judgment across Kubernetes · Service.
Kubernetes status names the stage where work stopped. Reading scheduler events, controller state, and object relationships beats debugging an application that never started.
- 01Use Kubernetes state to choose the next check
- 02Trace workload, Service, and storage relationships
- 03Recover safely under rollout constraints
SIMULATION STRUCTURE
Four evidence layers. No answer shown here.

Alert

Baseline
Compare the failing path with a known-good condition.
Finding
Identify the evidence that separates plausible causes.
Change
Choose a controlled recovery and a durable prevention step.
