A city library upgrades its cert-manager Helm chart during a change window so the release tracks a newer chart and app version. Which Helm action best describes moving that installed release forward?
Select an answer to reveal the explanation.
Short Explanation
Picture the library’s catalog software getting a scheduled upgrade—you do not throw out the whole catalog card drawer. helm upgrade slides the same named release to a newer chart or app version during the window. Uninstalling or recreating from scratch is the wrong tool for a planned chart bump.
Full Explanation
Helm tracks each install as a named release with revision history. helm upgrade applies a newer chart version and/or values to that release in place, which is the normal path for advancing cluster addons such as cert-manager. Operators should prefer upgrade over destructive uninstall/reinstall when the goal is a version bump with retained release identity and history.
