Overview

helm upgrade <release-name> <chart-name>

helm upgrade jazzy-manta archaeopteryx

Upgrade increments the revision number.

To keep a resource from being uninstalled during an upgrade, see helm uninstall - Keep a Resource from Being Uninstalled.

Options

--reuse-values

When upgrading, reuse the last release's values and merge in any overrides from the command line via --set and -f. If --reset-values is specified, this is ignored.

This is useful when the initial deployment was done with a configuration overlay, and we don't want to specify the same configuration overlay on upgrade.

--reset-values

See --reuse-values above.
