A Helm upgrade breaks the city’s permit search UI. Which action restores the prior successful release revision?
Select an answer to reveal the explanation.
Short Explanation
Bad upgrade? Hit the release time machine. helm rollback puts the release back on an earlier revision so the app returns to the last good chart/values state.
Full Explanation
Helm stores release revisions; helm rollback moves a release back to a specified prior revision and reconciles resources accordingly. That is the supported recovery after a bad upgrade. helm repo update refreshes chart indexes, deleting secrets destroys credentials/history rather than cleanly rolling back, and helm create only scaffolds a local chart.
