A transit Service shows no ready backends even though Pods are running. The Service selector is app=scheduler but Pods are labeled app=sched. What is the likely result?
Select an answer to reveal the explanation.
Short Explanation
Selectors are exact name tags — sched isn't scheduler, so the Service directory stays empty.
Full Explanation
A Service populates Endpoints/EndpointSlices only for Pods whose labels satisfy the Service selector. A mismatch yields empty backends and connection failures despite healthy Pods. There is no prefix fuzzy match or automatic label rewrite for ordinary Services.
