kubectl warns that a field in a Deployment manifest is deprecated, yet the apply still succeeds today. What should the application developer do?
Select an answer to reveal the explanation.
Short Explanation
A deprecated field is a porch light the city says it will unscrew next season. The house still works tonight, but you schedule the rewiring—migrate the field—before the light disappears mid-winter.
Full Explanation
Deprecated fields may continue to function while warnings appear, but they are scheduled for removal. Application developers should migrate to the supported fields proactively. Suppressing warnings, breaking selectors, or abandoning Deployments for naked Pods does not solve API evolution.
